Tourists Are Trashing the World’s Tallest Mountain, So China Has Banned Them From Its Base Camp
This picture taken on May 21, 2018 shows discarded climbing equipment and rubbish scattered around Camp 4 of Mount Everest. Decades of commercial mountaineering have turned Mount Everest into the world's highest rubbish dump as an increasing number of big-spending climbers pay little attention to the ugly footprint they leave behind.

China has closed its Everest base camp to tourists because of a buildup of trash on the world's tallest mountain.
The move comes as the Tibet Autonomous Region Sports Bureau said it had collected 8.4 metric tons (approximately 9.3 U.S. tons) of waste, including garbage and human waste, from the core area of the mountain last climbing season, ABC reported.
"[N]o unit or individuals are allowed entry into the core area of the Mount Qomolangma National Nature Reserve," notices posted by the local government in Dingri County, Tibet, read.
Qomolangma is what Everest is called in Tibet. While ABC News reported that the notices first appeared in December of 2018, the story has only been widely reported internationally in recent days, according to The Huffington Post.
Qomolangma National Nature Reserve Deputy Director Gesang Droma told ABC News that researchers and mountain climbers would still be able to access the mountain from the Chinese side with permits. The People's Daily said that only 300 permits would be granted this year. Tourists who want to view the north face of the mountain can still do so from the Rongbuk Monastery about a mile away from the base camp, Droma said.
The trashing of Everest has emerged as a growing problem in recent years, with some news outlets referring to it as the "world's highest garbage dump."
Both Nepal and China have previously implemented policies trying to encourage climbers to clean up after themselves. Nepal charges teams a $4,000 trash deposit that is returned if they bring down at least eight kilograms (approximately 17.6 pounds) of garbage. China fines climbers if they do not return with the same amount. Despite this, only half of climbers in 2018 brought down the minimum amount of trash, according to a video posted by The South China Morning Post.
Most climbers choose to climb Everest from Nepal. Of the 648 summits in 2017, only 217 left from the Tibetan base camp, ABC News reported. However, the Tibetan base camp is popular especially with Chinese tourists because it is accessible via car.

The gruesome images of whales and deer dying after mistaking plastic for food has helped put into perspective just how severe the plastic waste crisis is. Now, a new study finds that it is not just land and sea animals eating our plastic trash. It turns out that birds are eating hundreds of bits of plastic every day through the food they eat.
<p>The scientists from Cardiff University, the University of Exeter and the Greenpeace Research Laboratories found that birds along Britain's rivers are eating hundreds of fragments of microplastics daily because the worms and insects they feast on have also swallowed the plastics, making this the first study to show how plastic pollution makes its way up the food chain, as the <a href="https://www.bbc.com/news/science-environment-52762120" target="_blank">BBC</a> reported. The study was published in the journal <em>Global Change Biology</em>.</p><p>Previous research has noted that half of the insects in the rivers of south Wales contain microplastic fragments.</p>
<p>"The fact that so many river insects are contaminated makes it inevitable that fish, birds and other predators will pick up these polluted prey — but this is the first time that this type of transfer through food webs has been shown clearly in free-living river animals," said Joseph D'Souza, one of the study's researchers, to the <a href="https://www.bbc.com/news/science-environment-52762120" target="_blank">BBC</a>.</p><p>The Cardiff University researchers analyzed at plastic pollutants found in a bird known as a dipper, which wades or dives into rivers in search of underwater insects. They looked at droppings and regurgitated pellets from the birds and found microplastic fragments in roughly half of 166 samples taken from adults and nestlings at 14 of 15 sites studied.</p><p>"These iconic birds, the dippers, are ingesting hundreds of pieces of plastic every day," said Steve Ormerod, a professor at Cardiff University's Water Research Institute to the <a href="https://www.bbc.com/news/science-environment-52762120" target="_blank">BBC</a>. "They're also feeding this material to their chicks."</p><p>"In almost 40 years of researching rivers and dippers, I never imagined that one day our work would reveal these spectacular birds to be at risk from the ingestion of plastics — a measure of how this pollution problem has crept upon us," said Ormerod, as <a href="https://inews.co.uk/news/environment/british-birds-rivers-insects-microplastics-dippers-2861787" target="_blank">iNews</a> in the UK reported.<br></p>
<p>Similarly, another <a href="https://pubmed.ncbi.nlm.nih.gov/32388295/" target="_blank">study</a> published in the journal <em>Environmental Pollution</em> recently found that birds of prey in Florida swallow tiny bits of plastic debris at a rate of hundreds a day, particularly microplastic fragments made of polyester, polypropylene and nylon, as <a href="https://www.sustainability-times.com/environmental-protection/birds-of-prey-swallow-plenty-of-plastic-research-finds/" target="_blank">Sustainability Times</a> reported.</p><p>In that study, the researchers examined dozens of birds of prey, including hawks, ospreys and owls retrieved from the Audubon Center for Birds of Prey in Florida. From the 63 birds examined, representing eight different species, all were found to have microplastics in their GI tract, according to the <a href="https://pubmed.ncbi.nlm.nih.gov/32388295/" target="_blank">study</a>.</p><p>"Birds of prey are top predators in the ecosystem and by changing the population or health status of the top predator, it completely alters all of the animals, organisms and habitats below them on the food web," said Julia Carlin, the study's lead author, in a University of Central Florida <a href="https://www.ucf.edu/news/ucf-study-finds-microplastics-in-floridas-birds-of-prey-for-1st-time/" target="_blank">press release</a>.</p>

Plastic waste from the nearby city of Ushuaia is polluting nests and being found in penguins' stomachs and excrement. Deutsche Welle
Tierra del Fuego is at the southernmost tip of South America and is sometimes known as the "end of the world." This windswept part of Argentina is home to seven penguin colonies which breed, nest and feed in the area.
<p>Yet even here, the evidence of human encroachment on nature is clear.</p><p>Plastic waste from the nearby city of Ushuaia is <a href="https://www.dw.com/en/is-marine-plastic-pollution-a-threat-to-human-health/a-39161868" target="_blank">polluting</a> nests and being found in penguins' stomachs and excrement. And warmer waters mean adults must search longer for food, leaving their little ones more exposed to predators. Increasing tourism is also threatening the ecosystem.</p><p>Biologist Andrea Raya Rey has been studying the region's penguins for more than 20 years. She and others from the Austral Center for Scientific Research (CADIC) are working to protect the beloved flightless birds.</p>

Coastal Antarctica has seen has a curious phenomenon over the last few years. The green snow that hugs parts of its shores has started to spread farther inland. And it's all caused by the climate crisis.
<p>A <a href="https://www.nature.com/articles/s41467-020-16018-w" target="_blank">new study</a> published in the journal <em>Nature Communications</em> on Wednesday found that the green glow in the snow is actually caused by a microscopic <a href="http://www.ecowatch.com/tag/algae">algae</a> blooming on the surface of the snow, according to <a href="https://www.cbsnews.com/news/green-snow-algae-antarctica-spreading-climate-change/" target="_blank">CBS News</a>.</p><p>The researchers from the University of Cambridge in the UK and the <a href="https://www.bas.ac.uk/media-post/climate-change-will-turn-coastal-antarctica-green/" target="_blank">British Antarctic Survey</a> say the algae will spread as the planet heats up because warming temperatures are creating more of the slushy conditions that the algae need in order to thrive, according to <a href="https://www.theguardian.com/world/2020/may/20/climate-change-turning-parts-antarctica-green-say-scientists-algae" target="_blank">The Guardian</a>.</p><p>Where the algae are at their most dense, their bright green shine alters the appearance of the snow and is actually visible from space. The scientists also say that as the algae spreads, it will invite in other species that will feast on it as a potent source of nutrition, as <a href="https://www.theguardian.com/world/2020/may/20/climate-change-turning-parts-antarctica-green-say-scientists-algae" target="_blank">The Guardian</a> reported.</p>
<p>To conduct the study, the researchers looked at satellite data gathered between 2017 and 2019 and combined it with on-the-ground measurements over two summers in Antarctica. That process allowed the scientists to map the microscopic algae as they bloomed across the snow of the Antarctic Peninsula, according to <a href="https://www.cnn.com/2020/05/21/world/green-snow-antarctica-climate-change-intl-scli-scn/index.html" target="_blank">CNN</a>. The data was gleaned from images collected by the European Space Agency satellites with measurements from Antarctica's Ryder Bay, Adelaide Island, the Fildes Peninsula and King George Island.</p><p>What is reported is actually a conservative estimate since the data only included green algae. The satellite is only capable of picking up green, which means the data ignored the red and orange algae that accompany it.</p>
<p>"We now have a baseline of where the algal blooms are and we can see whether the blooms will start increasing as the models suggest in the future," said Matt Davey of the University of Cambridge's Department of Plant Sciences to <a href="https://www.reuters.com/article/us-climate-change-antarctica/climate-change-turning-antarcticas-snow-green-idUSKBN22W16F" target="_blank">Reuters</a>.</p><p>Even though mosses and lichens are the dominant plant species in Antarctica, the new mapping identified 1,679 separate algal blooms that are a key component in the continent's ability to capture carbon dioxide from the atmosphere, as <a href="https://www.reuters.com/article/us-climate-change-antarctica/climate-change-turning-antarcticas-snow-green-idUSKBN22W16F" target="_blank">Reuters</a> reported.</p><p>"The algal blooms in Antarctica are equivalent to about the amount of carbon that's being omitted by 875,000 average UK petrol car journeys," Davey said to <a href="https://www.reuters.com/article/us-climate-change-antarctica/climate-change-turning-antarcticas-snow-green-idUSKBN22W16F" target="_blank">Reuters</a>. "That seems a lot but in terms of the global carbon budget, it's insignificant. It does take up carbon from the atmosphere but it won't make any serious dent in the amount of carbon dioxide being put in the atmosphere at the moment."</p>
<p>The green snow appears along the Antarctic coast, which are "warmer" areas. There, the average temperatures reach just above freezing in the summer.</p><p>The researchers found that the distribution of green snow algae is strongly influenced by marine birds and mammals, because their excrement serves as an effective fertilizer. Over 60 percent of blooms were found near penguin colonies, and others were found near birds' nesting sites, according to <a href="https://www.cbsnews.com/news/green-snow-algae-antarctica-spreading-climate-change/" target="_blank">CBS News</a>.</p><p>"This is a significant advance in our understanding of land-based life on Antarctica, and how it might change in the coming years as the climate warms," said Davey in a <a href="https://www.cam.ac.uk/stories/antarctica-turning-green" target="_blank">press release</a>.</p><p>In order to flourish, the algae need a ready supply of water, which they should have an ample amount of as the planet heats up and snow on the Antarctica Peninsula melts.</p>
<p>"As Antarctica warms, we predict the overall mass of snow algae will increase, as the spread to higher ground will significantly outweigh the loss of small island patches of algae," said co-lead author Dr. Andrew Gray, of the University of Cambridge and the University of Edinburgh, as <a href="https://www.cbsnews.com/news/green-snow-algae-antarctica-spreading-climate-change/" target="_blank">CBS News</a> reported.</p><p>And the algae will help more snow melt.</p><p>"It's very dark — a green snow algal bloom will reflect about 45 percent of light hitting it whereas fresh snow will reflect about 80 percent of the light hitting it, so it will increase the rate of snow melt in a localized area," said Gray to <a href="https://www.cnn.com/2020/05/21/world/green-snow-antarctica-climate-change-intl-scli-scn/index.html" target="_blank">CNN</a>.</p>

Biodiversity – the diversity within species, between species and of ecosystems – is declining globally, faster than at any other time in human history. Csondy / Getty Images
By Marie Quinney
Biodiversity is critically important – to your health, to your safety and, probably, to your business or livelihood.
<p>But biodiversity – the diversity within species, between species and of ecosystems – is declining globally, faster than at any other time in human history. The world's 7.6 billion people represent just 0.01% of all living things by weight, but humanity has caused the <a href="https://www.theguardian.com/environment/2018/may/21/human-race-just-001-of-all-life-but-has-destroyed-over-80-of-wild-mammals-study" target="_blank">loss of 83% of all wild mammals and half of all plants</a>. (Biodiversity loss and ecosystem collapse is one of the top five risks in <a href="https://www.weforum.org/reports/the-global-risks-report-2020" target="_blank">the World Economic Forum's 2020 Global Risks Report</a>, too.)</p><p>In celebration of <a href="https://www.cbd.int/idb/" target="_blank">the International Day for Biological Diversity</a>, we break down the five ways in which biodiversity supports our economies and enhances our wellbeing – and has the potential to do even more.</p>
1. Biodiversity Ensures Health and Food Security.
<p>Biodiversity underpins global nutrition and food security. Millions of species work together to provide us with a <a href="https://www.cbd.int/health/doc/Summary-SOK-Final.pdf" target="_blank">large array of fruits, vegetables and animal products essential to a healthy, balanced diet</a> – but they are increasingly under threat.</p><p>Every country has indigenous produce – such as wild greens and grains – which have adapted to local conditions, making them more resilient to pests and extreme weather. In the past, this produce provided much-needed micronutrients for local populations. Unfortunately, however, the <a href="http://www.fao.org/3/a-i1620e.pdf" target="_blank">simplification of diets, processed foods and poor access to food have led to poor-quality diets</a>. As a result, <a href="https://www.bioversityinternational.org/research-portfolio/diet-diversity/biodiversity-for-food-and-nutrition/" target="_blank">one-third of the world suffers from micronutrient deficiencies</a>.</p><p>Three crops – wheat, corn and rice – <a href="https://enviroliteracy.org/food/crops/" target="_blank">provide almost 60% of total plant-based calories consumed by humans</a>. This leads to reduced resiliency in our supply chains and on our plates. For example, <a href="http://www.fao.org/3/a-i1620e.pdf" target="_blank">the number of rice varieties cultivated in Asia has dropped from tens of thousands to just a few dozen; in Thailand, 50% of land used for growing rice only produces two varieties</a>.</p><p>People once understood that the conservation of species was crucial for healthy societies and ecosystems. We must ensure this knowledge remains part of our modern agricultural and food systems to prevent diet-related diseases and reduce the environmental impact of feeding ourselves.</p>2. Biodiversity Helps Fight Disease.
<p>Higher rates of biodiversity have been linked to an increase in human health.</p><p>First, plants are essential for medicines. For example, <a href="http://www3.weforum.org/docs/WEF_New_Nature_Economy_Report_2020.pdf" target="_blank">25% of drugs used in modern medicine are derived from rainforest plants</a> while <a href="http://www3.weforum.org/docs/WEF_New_Nature_Economy_Report_2020.pdf" target="_blank">70% of cancer drugs are natural or synthetic products inspired by nature</a>. This means that every time a species goes extinct, we miss out on a potential new medicine.</p><p>Second, <a href="https://www.nature.com/articles/news.2010.644" target="_blank">biodiversity due to protected natural areas has been linked to lower instances of disease</a> such as Lyme disease and malaria. While the exact origin of the virus causing COVID-19 is still unknown, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5711306/" target="_blank">60% of infectious diseases originate from animals</a> and <a href="https://sustainabledevelopment.un.org/content/documents/631980-Machalaba-Anthropogenic%20Drivers%20of%20Emerging%20Infectious%20Diseases.pdf" target="_blank">70% of emerging infectious diseases originate from wildlife</a>. As human activities encroach upon the natural world, through deforestation and urbanization, we reduce the size and number of ecosystems. As a result, animals live in closer quarters with one another and with humans, creating ideal conditions for the spread of zoonotic diseases.</p><p>Simply put: <a href="https://www.nature.com/articles/news.2010.644" target="_blank">more species means less disease</a>.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzMxMDYyOC9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY0MDA4MjA5MH0.7QU59zfy44cq0wSAwMxeqjyygJi9ef1aEyYHQZ3gCts/img.png?width=980" id="77368" class="rm-shortcode" data-rm-shortcode-id="18d555bb10422495fc147f109cb72b3b" data-rm-shortcode-name="rebelmouse-image" />
Human activity is eroding biodiversity. World Economic Forum Nature Risk Rising
3. Biodiversity Benefits Business.
<p>According to the World Economic Forum's recent <a href="http://www3.weforum.org/docs/WEF_New_Nature_Economy_Report_2020.pdf" target="_blank">Nature Risk Rising Report</a>, more than half of the world's GDP ($44 trillion) is highly or moderately dependent on nature. Many businesses are, therefore, at risk due to increasing nature loss. <a href="https://wwf.panda.org/our_work/biodiversity/protected_areas/arguments_for_protection/goods_services/medicine/" target="_blank">Global sales of pharmaceuticals based on materials of natural origin are worth an estimated $75 billion a year</a>, while natural wonders such as <a href="https://wwf.panda.org/knowledge_hub/all_publications/living_planet_report_2018/" target="_blank">coral reefs are essential to food and tourism.</a></p><p>There is great potential for the economy to grow and become more resilient by ensuring biodiversity. <a href="http://wedocs.unep.org/xmlui/handle/20.500.11822/31813" target="_blank">Every dollar spent on nature restoration leads to at least $9 of economic benefits.</a> In addition, <a href="https://www.foodandlandusecoalition.org/global-report/" target="_blank">changing agricultural and food production methods could unlock $4.5 trillion per year in new business opportunities by 2030</a>, while also preventing trillions of dollars' worth of social and environmental harms.</p>4. Biodiversity Provides Livelihoods.
<p>Humans derive approximately <a href="https://livingplanetindex.org/home/index" target="_blank">$125 trillion of value from natural ecosystems each year</a>. Globally, <a href="http://www.unesco.org/new/en/natural-sciences/environment/water/wwap/wwdr/2016-water-and-jobs/" target="_blank">three out of four jobs</a> are dependent on water while the agricultural sector employs over <a href="https://www.conservation.org/priorities/livelihoods" target="_blank">60% of the world's working poor</a>. In the Global South, forests are the source of livelihoods for <a href="https://www.conservation.org/priorities/livelihoods" target="_blank">over 1.6 billion people</a>. In India, forest ecosystems contribute <a href="https://www.ncbi.nlm.nih.gov/pubmed/19915547" target="_blank">only 7% to India's GDP yet 57% of rural Indian communities' livelihoods</a>.</p><p><span></span>Ecosystems, therefore, must be protected and restored – not only for the good of nature but also for the communities that depend on them.</p><p>Although some fear environmental regulation and the safeguarding of nature could threaten businesses, the "restoration economy" – the restoration of natural landscapes – provides more jobs in the United States than most of the extractives sector, with the potential to create even more. According to some estimates, the restoration economy is worth <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0128339" target="_blank">$25 billion per year and directly employs more than the coal, mining, logging and steel industries altogether</a>. Nature-positive businesses can provide <a href="https://www.greenbiz.com/article/10-things-you-need-know-about-restoration-economy" target="_blank">cost-effective, robot-proof, business-friendly jobs</a> that stimulate the rural economy without harming the environment.</p>5. Biodiversity Protects Us.
<p>Biodiversity makes the earth habitable. Biodiverse ecosystems provide <a href="https://www.nature-basedsolutions.com/" target="_blank">nature-based solutions</a> that buffer us from <a href="https://oceanservice.noaa.gov/facts/coral_protect.html" target="_blank">natural disasters such as floods and storms</a>, <a href="https://digital.iucn.org/water/nature-based-solutions-for-water/" target="_blank">filter our water</a> and <a href="https://www.naturebasedsolutionsinitiative.org/publications/the-superior-effect-of-nature-based-solutions-in-land-management-for-enhancing-ecosystem-services/" target="_blank">regenerate our soils</a>.</p><p>The <a href="https://blogs.worldbank.org/voices/miracle-mangroves-coastal-protection-numbers" target="_blank">clearance of over 35% of the world's mangroves for human activities</a> has increasingly put people and their homes at risk from floods and sea-level rise. If today's mangroves were lost, 18 million more people would be flooded every year (an increase of 39%) and annual damages to property would increase by 16% ($82 billion).</p><p>Protecting and restoring natural ecosystems is vital to fighting climate change. Nature-based solutions could provide <a href="https://www.pnas.org/content/114/44/11645" target="_blank">37% of the cost-effective CO2 mitigation needed by 2030</a> to maintain global warming within 2°C (35.6 F).</p><p>Natural ecosystems provide the foundations for economic growth, human health and prosperity. Our fate as a species is deeply connected to the fate of our natural environment.</p><p>As ecosystems are increasingly threatened by human activity, acknowledging the benefits of biodiversity is the first step in ensuring that we look after it. We know biodiversity matters. Now, as a society, we should protect it – and in doing so, protect our own long-term interests.</p>From Your Site Articles

The climate crisis has caused Japanese cherry blossoms to bloom in October and sped the arrival of spring in much of the U.S. But it turns out that humans aren't the only animals who can trick plants into flowering early.
<p><br/></p>
<p>Scientists have discovered that <a href="https://www.ecowatch.com/tag/bees" target="_self">bumblebees</a> can cause plants to flower as much as 30 days ahead of schedule by biting their leaves.</p><p>"I think it's fascinating how much we still don't know about organisms that we think we know really well," study coauthor and ETH Zurich professor Consuelo De Moraes <a href="https://www.bbc.co.uk/news/science-environment-52759804" target="_blank">told BBC News</a>. "It absolutely increases our sense of wonder at the cleverness of nature in all its many forms."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="8c2bff1db53183539dd61a18086f2683"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/3z1OH_ebxrI?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>The discovery, published in <a href="https://science.sciencemag.org/content/368/6493/881" target="_blank">Science Friday</a>, was made by accident. One of De Moraes' students, Foteini Pashalidou, observed buff-tailed bumblebees making small slits in the leaves of greenhouse plants, <a href="https://www.nationalgeographic.com/animals/2020/05/bumblebees-bite-plants-flower-early/" target="_blank">National Geographic</a> explained. However, the bees didn't appear to eat the leaf bits or bring them back to their nests.</p><p>The researchers did notice that the bees from colonies with less food were the ones most damaging the leaves, <a href="https://www.sciencemag.org/news/2020/05/hungry-bumblebees-make-plants-flower-early-cutting-holes-their-leaves" target="_blank">Science reported</a>. This led the scientists to wonder if the bees were trying to get the plants to flower early out of hunger, so they set up an experiment to test this hypothesis, as Science described:</p><blockquote>The researchers set up a greenhouse experiment with black mustard (<em>Brassica nigra</em>), a crop they had been studying. Ten plants were put in mesh bags with bumble bees that hadn't eaten any pollen for 3 days; they proceeded to nibble five to 10 holes in each plant. On average, <a href="https://science.sciencemag.org/cgi/doi/10.1126/science.aay0496" target="_blank">those plants flowered after 17 days</a>; undamaged plants that had not been exposed to bumble bees took an average of 33 days, the researchers report today in Science. In a similar experiment, tomato plants sped up their flowering by 30 days.</blockquote>
<p>Further experiments confirmed that the behavior was motivated by hunger. Pollen-deprived bees cut four times as many holes in lab leaves as fully fed bees. Outside the lab, bees cut holes in plants on a rooftop garden in early spring, but stopped doing so as frequently once more flowers began to bloom. The researchers also observed leaf-biting in two wild species: red-tailed and white-tailed bumble bees.</p><p>"That was super exciting," De Moraes told Science.</p><p>While this behavior is new to scientists, we may have encountered its evidence for years without realizing it. </p><p>"You see these semi-circular sort of incisions, often in the leaf," coauthor Dr Nark Mescher told BBC News. "One of the students was saying that they were eating a salad the other day, and they saw that kind of damage on the leaf that was probably from a bumblebee."</p>
<p>Beyond its novelty, the finding has important implications for bumblebees' ability to adapt to the climate crisis, National Geographic explained. As warmer spring temperatures cause <a href="https://www.ecowatch.com/tag/pollinators" target="_self">pollinators</a> to awaken before plants flower, this activity could ensure early-rising bees find food. It might also help farmers increase human food supply if they can copy the bees' technique.</p><p>But so far the researchers aren't sure how the bees' trick works. Attempts to duplicate it in the lab by damaging leaves in similar ways were only partially successful.</p><p>"We really tried to replicate it with the best of our ability," De Moraes told BBC News. "It's possible that the bees also have some cue that they are providing to the plants that is specific to the bee. And that could be secretions that we don't know about, but it's something that we plan to investigate."</p>

Even if we escaped getting sick from the coronavirus, we are all sick of staying at home, practicing social distancing and wearing masks. While case numbers and deaths from COVID-19 are trending downward, this is not the time to let down your guard. These are not ordinary days. These novel days call on us to make decisions with limited and evolving information. The coronavirus is still circulating.
<p>As a <a href="http://humanmedicine.msu.edu/FACULTY_STAFF/Faculty-Peer-Support-Program.htm" target="_blank">physician</a> who has practiced for over 30 years, I find myself facing the decisions about safe outdoor recreation with some trepidation. The decision about whether to go to a beach, a pool or a park was previously pretty simple – now, not so much.</p><p>On one hand, there is too much information, some of it conflicting and much of it infused with political ideology. On the other, there is a lack of information – the "novel" in novel coronavirus means it's new and there is much we don't know. While it remains as true as ever that there are <a href="https://www.health.harvard.edu/newsletter_article/a-prescription-for-better-health-go-alfresco" target="_blank">tremendous benefits to going outside</a> these days, it's also true there are risks to yourself and to others in doing so.</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="17b3f211c4733cf8b8e516241530a7bd"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/HF-JctuNWus?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>How to decide whether you and your loved ones can go hiking, beaching or swimming? Let's begin with some facts that we actually do know. We know that the virus can be carried asymptomatically, and we know that there are <a href="https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/people-at-higher-risk.html" target="_blank">people at disproportionately high risk</a> of serious complications.</p><p>We scientists and doctors don't know yet if having antibodies is indicative of immunity, so a positive antibody test doesn't mean you're good to go without risk. We know that the number of virus particles you are exposed to and the <a href="https://www.erinbromage.com/post/the-risks-know-them-avoid-them" target="_blank">duration of exposure</a> are vital factors determining risk of transmission.</p><p>Also, at least one preprint study, which has not been peer-reviewed, found that the risk of <a href="https://doi.org/10.1101/2020.04.04.20053058" target="_blank">outdoor exposure is much less</a> than that indoors.</p>
But I Want to Be Outside.
<p>Now that almost all states have opened back up, in varying degrees, it is important to remember that the virus is still out there. The risks of getting infected when passing by a runner or cyclist fairly quickly are not terribly high, at least in the absence of a sneeze or cough, and are even lower at a distance. Solitary activities transmit fewer particles than team sports or horseplay in the pool.</p><p>Going alone or only with the people in your <a href="https://www.cnn.com/2020/04/30/health/how-to-form-a-bubble-wellness/index.html" target="_blank">quarantine bubble</a> will minimize your risk. Proximity to people outside your bubble means <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/diy-cloth-face-coverings.html" target="_blank">you should wear a mask properly</a> to protect others. The <a href="https://arxiv.org/ftp/arxiv/papers/2004/2004.07052.pdf" target="_blank">quarantine bubble</a> is shorthand for a small group of friends you may choose to get together with who have followed social distancing guidelines and whom you know to be healthy. The safety of your bubble, however, is only as good as the agreement between members to follow safety precautions outside the bubble.</p><p>Look at the logistics of your plan. It's worth breaking your intended activity down to basic steps.</p><ul><li>How will you get there? Remember, public transportation and air travel are still high-risk. And, if you are driving on the highway or interstate, remember that you might need to stop for bathroom breaks. In the spirit of "better safe than sorry," if you do travel long distances by car, bring your own food and water as well as a hygiene kit containing wipes, paper towels, travel soap and sanitizer.</li><li>What will I need while there? Consider the need for bathroom breaks, food and water, your ability to wash hands and maintain distance. Bathrooms and changing rooms are full of "high touch" surfaces, and while definitive information is lacking, early evidence demonstrates <a href="https://doi.org/10.3201/eid2607.200885" target="_blank">virus persistence</a> on surfaces. You should treat public bathrooms as high-risk areas and keep in mind that many may not even be open.</li></ul><p>Once at your destination, remember the coronavirus basics.</p><ul> <li>Keep a distance of at least six feet.</li><li>Wash and disinfect your hands often – and definitely after touching any shared surface.</li><li>Keep your hands away from your face.</li><li>Wear a mask.</li><li>If at a park, walk or hike single file and leave room for others to pass at a safe distance. Consider going at off-peak hours and to less popular locations.</li><li>If going to the beach, you still need to wear a mask. And keep your distance.</li><li>If going to the pool, remember that although there is <a href="https://www.cdc.gov/coronavirus/2019-ncov/php/water.html" target="_blank">no evidence of spread through water</a> that has been treated per recommendations, common areas require distancing, masks and the other usual precautions.</li></ul><p><span></span></p><p>Remember the real estate adage "location, location, location." The <a href="https://coronavirus.jhu.edu/map.html" target="_blank">virus prevalence and the slope </a> – whether cases are rising or falling – in your area matter. Also, the <a href="https://www.cnet.com/health/coronavirus-testing-near-me-how-to-find-covid-19-test-sites-and-wait-times/" target="_blank">availability of testing</a> and of <a href="https://sccm.org/Blog/March-2020/United-States-Resource-Availability-for-COVID-19" target="_blank">hospital beds in your area </a> are things to consider.</p><p>You should take into account the <a href="https://www.nytimes.com/interactive/2020/us/states-reopen-map-coronavirus.html" target="_blank">regulations and laws in your area</a>, understanding that they may not reflect public health guidelines. If in doubt, err on the side of protection.</p><div></div>
Factors Out of Your Control
<p>Finally, there is the wild card of figuring out what the people around you will be doing to protect you as you are deciding how you will protect yourself, your loved ones and them. Will they respect your space and wear masks? The final word on outdoor recreation? Of course, go out and be active. It's important for your mental and physical health. But, choose wisely, be prepared and stay safe.</p>From Your Site Articles

Six years ago, during a global coral bleaching event and after the Port of Miami was dredged, endangered corals on Florida's coral reef began rapidly wasting away and dying. Their "mystery killer," whose exact pathogen still remains unidentified, is referred to as the "Stony Coral Tissue Loss Disease" (SCTLD).
<p>In response, scientists launched an unprecedented, "Hail Mary" rescue effort to save the corals from local extinction. The first phase of the groundbreaking project concludes next week.</p><p>SCTLD is different and more devastating than other coral diseases because of how quickly it can kill an entire coral colony, how many different species it infects, how long it has lingered and how much remains unknown about its origins, University of Miami Rosenstiel School of Marine Science professor Andrew Baker told EcoWatch.</p><p>"Corals affected by SCTLD lose tissue really fast," he said. "Unlike many other coral diseases that can take weeks or months to pass over a coral's surface, SCTLD can kill a colony within a few days under 'ideal circumstances.' Some species, principally the brain corals, have almost disappeared from local reefs within a period of about six months."</p>
<p>The coral biologist also noted that SCTLD was particularly difficult to eradicate because it affects almost half of Florida's coral species, which has allowed it to persist in reef communities for a long time because it has so many different hosts it can inhabit.</p><p>SCTLD now threatens the entire Florida Reef Tract (360 linear miles), which is the third-largest coral barrier reef in the world, decimating important reef-building and endangered corals in its path.</p><p>"It's really sad. Some of these corals that have been growing for tens to hundreds to possibly thousands of years are disappearing in months," said <a href="https://myfwc.com/" target="_blank">Florida Fish and Wildlife Conservation Commission (FWC)</a> coral caretaker Allan Anderson. "We're talking about corals that have literally built this reef now dying, and it's pretty scary that something we can't yet identify is destroying everything."</p>
<p>For the past two years, Anderson and his FWC Coral Rescue Team colleagues have taken matters into their own hands — literally — by using hammers and chisels to remove healthy, at-risk corals from the reefs before the disease reaches them.</p><p>"At first I was kinda sad about collecting corals off the reef," said Tanya Ramseyer, FWC Coral Rescue project coordinator. "Your whole life, you're told not to touch the corals, and here, they tell us, 'Here's a hammer and chisel. You're gonna go down and take these off the reef.' But we're saving these corals in the nick of time. That's how I work myself up to it. We're rescuing these corals."</p><p>Scuba diving off charter and research vessels, the Coral Rescue Team identifies, collects, measures and samples corals susceptible to SCTLD that would likely perish if left on the reef.</p>

<p>"The rescue mission is exactly what it sounds like," FWC Coral Program research assistant Ananda Ellis told EcoWatch. "We're trying to collect these corals and take them out of their natural environment before they get hit with this disease. Most of the individuals we're collecting would have been affected and dead within X amount of period, depending on the species, so we're definitely at that last stage. We do need to collect these corals."</p><p>To date, the team has completed six rescue cruises, and their last cruise is scheduled for May 27, Ellis shared. They have collected nearly 2,000 individual corals from 22 target species. Genetic sampling ensured they had enough unique genotypes of each species to preserve genetic diversity during the next phase of the rescue mission — coral propagation for future restoration activities, said Stephanie Schopmeyer, a main FWC coordinator for the rescue cruises.</p>

<p>Rescue corals are shipped to partner universities, non-governmental organizations, zoos and aquaria around the country for study and safekeeping. The corals will remain in these new homes indefinitely. Many have never been observed in captivity before, and <a href="https://www.ecowatch.com/florida-aquarium-coral-reefs-2639990687.html" target="_self">researchers have already successfully experimented</a> with sexual and asexual propagation techniques to create new "coral babies."</p><p>"Over time, we should be able to breed or propagate or grow enough coral to repopulate the entire reef tract," Schopmeyer said. "That is the actual goal."</p><p>The final phase of the rescue project will occur when it is safe for the original rescue corals and their offspring created in holding facilities to be reintroduced to the wild in numbers that will hopefully help restore what the disease has ravaged.</p>

<p>The Coral Rescue Team is part of a broader, extensive, multi-agency effort to track the spread of SCTLD, identify the pathogen, develop methods to lessen the effects of the disease on reefs and to rescue corals for safekeeping in zoos and aquaria around the country.</p><p>Lessons learned are being applied in the <a href="https://www.ecowatch.com/mysterious-disease-caribbean-reefs-2639164702.html" target="_self">Caribbean and other reefs</a> where the deadly disease has possibly been <a href="https://safety4sea.com/uscg-preventing-potential-spreading-of-stony-coral-tissue-loss-disease-from-ballast-water/?__cf_chl_jschl_tk__=4b4c6e774965065c21c60c807eb673bad1622c5d-1590144282-0-AevbNTlctVvPtYUNecZo3kOK9fI48Dc2XlfjQEMfynvwuFF4dsT54sPf-GCVbUtUjGWWM0UA9q67XX3TlUHvopZoG3JvWsyumIfJgadeazKe3Q3JpyChDKwhVT9e8_w8VyGTLauXYLi5nd1kb0ctvI0whw0spp2ww4okWIsCEBJaDFOe9cR4VsV_VFFz_bLANUSjeISYVFjWp6i7XedKoXSj2mlxBxuN3zWUTTtipBpsHrjiMzMilQPHRUzv3rSSbGDdPl8ksygzY4dbIW-J3lOjxp69OYLm9nhDxkmwyKpz2pStHf7Sh7mKMhDP6OkZcdI1NBsJG3UgtwCzmbZH_JEK-kjTkfw4GZrl2pxyBxz2EH4VCJZomjQGJGGpHjEnbgxVsXaLwlW90yXtYAkHuF8" target="_blank">transported in ballast water from ships</a>.</p><p>"It's a brave new reef out there," Baker said. "It's an exciting time to be a coral biologist because these interventions have never been tried before, and we're in a position where we have to start trying them."</p><p>"If you aren't trying," Ellis said, "then you've already determined the outcome. We don't know what the outcome is yet, because we're still trying.
