Earth’s population is ballooning every day, which increasingly presents a host of challenges, from housing to resource depletion to food.
The issue of feeding billions of people on a warming planet—along with related concerns such as food waste, water usage and greenhouse gas emissions—continues to be explored.
It has been widely established that factory farming contributes to climate change and even that eating less beef will benefit the environment. But what about eating … bugs. Bugs?
Two billion people around the globe eat insects. Major areas of consumption include Latin America, Southeast Asia and Central Africa. As new ways are examined to feed a rapidly expanding global population, and with a minimal environmental impact, will entomophagy—the consumption of insects as food—be taken seriously in other parts of the world?
Folks at Ensia—Anna Egelhoff, John Sisser and Todd Reubold—put together this infographic to address that very question:
Have you ever eaten an insect? Would you?

"Brush three times a day!" You probably grew up hearing that conventional oral-hygiene wisdom, but unfortunately, doing so today could pose an unnecessary threat to your health, thanks to certain bad-actor ingredients cropping up in popular toothpaste brands. The kicker? Some of the worst ingredients don't even help keep your teeth cleaner. "Does the risk outweigh the benefits?" asks Linda A. Straub-Bruce, BS Ed, RDH, author of Dental Herbalism. "It's what I always ask my patients to consider."
She recommends avoiding these six ingredients that just aren't worth the risk:
1. Sodium Laurel Sulfate (SLS)
SLS seems to fuel canker sores. Researchers have linked SLS to higher numbers of canker sore outbreaks. As if that's not enough, SLS also seems to cause more frequent outbreaks that last longer, too, Straub-Bruce says. She also points out that there is a definite correlation with cold sensitivity as well. No one likes canker sores or sensitive teeth, so manufacturers must have a really good reason to justify its inclusion, right?
Nope.
"All it does is foam," explains Straub-Bruce. "There is no other viable purpose other than the experience. This doesn't translate into better health or lower microbial load, but people associate foaming with clean." In fact, she suggests that you get more cleaning power from the scraping action of brushing or flossing (or even just eating a carrot) than you do from SLS.
2. Triclosan
"About 15 years ago, triclosan came to oral care because it fights the bacteria in plaque for up to 12 hours," says Straub-Bruce. Unfortunately, research is now showing that, much like BPA, triclosan is a hormone disruptor.
"And now that it's been out for a long time and it's been going down the drain, we're starting to see the environmental impacts," says Straub-Bruce. She points out that not only is it a hormone disruptor for people, but it's also a food-chain disruptor because it affects algae.
3. Blue #1 and #2
The "benefit" of these dyes is pretty obvious: They color the toothpaste. That's it. Unfortunately, the fun color is offset by some pretty serious health concerns. "When swallowed it's a respiratory irritant, digestive tract irritant, and there have been correlational studies between blue #1 and behavioral problems in children," says Straub-Bruce.
4. Flavoring
Sure, we love the minty-fresh taste, but what do the toothpaste companies add to make their pastes palatable? "No matter what it says on the front, you have to read the back," says Straub-Bruce. It's important to watch out for flavoring agents like aspartame. If you're making the jump to natural herbal rinses and need help getting used to the new taste, she recommends looking for natural sweeteners like xylitol or stevia.
5. Hydrated Silica
This chemical is used for stain removal, but Straub-Bruce explains that it doesn't break down over time. "This means that it can damage your enamel," she says. She recommends using baking soda instead. You'll get sparkling teeth—without destroying them.
6. Alcohol
Straub-Bruce points out that alcohol is a false friend when it comes to mouth rinses: "Alcohol is an antimicrobial, but it's also a drying agent," she says. "So while it freshens your breath initially, it flips back twofold later because the bacteria thrive in a dry mouth."
Instead, Straub-Bruce suggests making a tea of herbs (and letting it cool) as a rinse. To freshen your breath, try brewing a 2:1:1:0.5 ratio of cardamom, cumin, fennel and orange peel in water. After it's cooled, rinse as you would with your regular mouthwash.

The Pacific Ocean and Pacific Islands are in trouble, and not just from the recent spate of storms.
Because of climate change, oceans are facing increasing acidification, which is devastating to marine life, and islands face the threat of disappearing due to sea level rise.
But there is always hope.
The Pew Charitable Trusts’ Global Ocean Legacy project has played a key role in urging governments to protect almost one million square miles of ocean from ecosystem threats. Their latest undertaking? Urging President Obama to expand and protect the Pacific Remote Islands Marine National Monument.
The planned expansion of the national monument, announced in June, would create an area larger than Alaska, increasing protection of U.S. waters in the Pacific by up to 671,000 square miles. Extending the boundaries would result in the world’s most extensive network of marine protected areas, which, as research shows, is essential to increasing oceans species’ diversity and resilience to climate change.
While the national monument expansion is still under consideration by the Obama administration, a group of Pacific Islanders called the Pacific Climate Warriors are doing their part to protect their home from the effects of climate changes, telling the world: "We are not drowning. We are fighting.”
The Pacific Climate Warriors have been building traditional canoes in preparation for an epic journey to Australia this October, where they will stand up to those blocking climate action and to the fossil fuel industry that is destroying their homelands.
350 Pacific, active in 15 of the Pacific Island Nations, launched a video explaining the mission of the campaign:
The Pacific Warriors will travel Australia and share their story of struggle, confident that Australians will stand up and say “we will not let our neighbors drown.”
As the group states:
For 20 years we’ve asked world leaders to take action to stop polluting the atmosphere. Unless we act now, many of our Pacific Islands face losing everything to sea level rise. We cannot wait any longer.

Toxicologists have a saying: “The dose makes the poison.” In other words, there is no such thing as “toxic” or “non-toxic”—it always depends on how much of a substance you consume.
So what’s a toxic level of mercury in your diet? This has long been a concern, because many fish contain measurable levels of mercury, which can cause profound neurological disease and death if consumed in sufficient amounts. The issue gained new urgency last week when a study in the journal Nature showed that mercury concentration at the ocean surface has tripled since the beginning of the industrial era.
How does mercury get into fish, anyway?
In the 19th and 20th centuries, factories dumped massive amounts of methylmercury—the most dangerous form of mercury, bonded to carbon and hydrogen—directly into waterways. The most infamous example occurred in Japan in the 1950s and '60s, when industrial mercury poisoned more than 2,000 people who ate fish from Minamata Bay. (The neurological syndrome caused by severe mercury poisoning is called “Minamata disease” after the tragedy.)
Mercury dumping has been a problem in the U.S., too. I grew up a few miles from New York’s Onondaga Lake, where the Allied Chemical Company disposed of as much as 20 pounds of mercury per day in the mid-2oth century. “America’s most polluted lake” is still recovering.
Mercury can also take a less direct route to the sea. Burning fossil fuels releases mercury into the air—around 160 tons per year in the U.S. The mercury settles to the ground, where rains eventually wash it to the ocean. There, elemental mercury turns into methylmercury. Scientists aren’t quite sure how this conversion occurs, but it probably involves the metabolism of a small but abundant living creature. When that creature is eaten by bigger creatures, the methylmercury travels up the food chain, collecting in animal tissue in larger and larger amounts. That's why predators like tuna have troubling levels of mercury—they eat a lot.
What are the effects of mercury exposure?
Cases of mercury poisoning go back thousands of years. Mercury probably killed the first Chinese emperor, Qin Shi Huang, in 210 B.C.E. at the age of 39. He believed mercury pills would grant him immortality (oops). But Mercury doesn’t just kill. It can first drive a victim to insanity. The phrase “as mad as a hatter” harkens back to Victorian England, where mercury was used in haberdasheries. (Mercury inhalation is still a problem in many workplaces.)
Mercury’s notoriety as a poison derives from these instances of acute exposure. Diagnosing these cases is clinical child’s play. The symptoms—like numbness in the extremities, weakness, and a narrowing of the field of vision—are well known, and they appear soon after exposure. The challenge for toxicologists is sussing out the more subtle effects of lower doses of mercury, like the ones you might get from eating fish.
Fetuses and small children, for example, are extremely sensitive to mercury. Exposure to mercury in the womb can affect cognitive development, impair memory and attention, and slow language acquisition, even when the doses are too low to cause any observable symptoms in the mother.
Chronic, low-dose exposure in adults could also be a concern. Some doctors believe that trace levels of mercury contribute to heart disease and high blood pressure, though the evidence for this is currently inconclusive. These claims are based on a small number of studies conducted on discrete populations living in remote areas. In addition, the precise mechanism that would link low-dose mercury to heart disease isn’t fully understood.
So how much is too much?
The U.S. Environmental Protection Agency (EPA) recommends consuming a daily maximum of 0.1 micrograms of mercury for each kilogram of your body weight. That would limit a 176-pound adult (the national average) to 8 micrograms of mercury each day.
What does that mean in terms of cans of tuna or pieces of sashimi? Well, you’ll need a species-by-species chart of mercury concentration to figure that out. The amount of mercury in certain types of fish varies greatly. For instance, the average adult could eat 13 ounces of fresh salmon per day while staying under the EPA recommended maximum. You should avoid swordfish, though—eating just 0.14 ounces, a mere forkful, would put you over the limit.
If you don’t want to break out your calculator and metric system conversion charts, use this handy seafood calculator from Natural Resources Defense Council (which publishes OnEarth) for an estimate of your weekly mercury consumption.
These calculations can be helpful, but there are caveats. Not all scientists agree with the EPA’s mercury limits, and many more would add the proviso that they represent an extremely rough guess at what constitutes a safe level. In addition, the recent Nature study shows that oceanic mercury levels are on the rise, and existing research suggests that trend may continue for centuries. As increasing mercury concentrations travel up the food chain, the amount of fish you’ll be able to consume while staying within the EPA’s “safe zone” will decrease over time.
The federal government (and the fishing industry, naturally) don’t recommend avoiding fish altogether. Almost immediately after I received notification of the Nature study, the U.S. Food and Drug Administration Twitter account recommended increased fish consumption for pregnant women. (My colleague Jason Bittel has more details about the new federal fish-eating guidelines.) It’s tough, with all the conflicting advice, to know for sure what to do.
Promising developments?
But there’s hope! Last November, the U.S. joined the Minamata Convention on mercury. If enacted, this international agreement would prohibit new mercury mines, regulate the industrial use of mercury and reduce mercury emissions from coal-fired power plants.
Now for the bad news. Although 100 countries have signed on, the U.S. is the only nation that has gone through the official legal processes required to accept the convention. It will take 49 others before the agreement goes into force. So after budgeting a few years for that, plus a century or two before ocean mercury levels actually begin to drop, maybe you should leave the swordfish to your distant descendants.

As the Ebola virus is ravaging parts of West Africa, recent reports are linking the outbreak to past studies holding climate change accountable for the uptick in viral diseases.
In 2006, a study published in the journal Transactions of the Royal Society of Tropical Medicine and Hygiene revealed that Ebola, a “violent hemorrhagic fever that leads to internal and external bleeding,” would be more frequent with global warming due to its intermittent connection to wildlife and climate. In 2008, another study reiterated the same fears, noting that Ebola outbreaks would be among a cluster of other diseases gaining momentum, such as bird flu, cholera, plague and tuberculosis.
“We are calling for increased attention and action in developing global monitoring networks to look at a wide variety of infectious diseases in a wide variety of wildlife since they are such sensitive indicators of the health of the systems in which they live,” said veterinarian William Karesh, Wildlife Conservation Society’s (WCS) vice president of global health programs, back in 2008.
In light of the recent outbreak, some researchers are connecting deforestation in countries such as Liberia to the disease, noting that the change in landscape is bringing wildlife in closer contact with humans. According to researchers, the virus is typically found in wildlife, and transmission from animals to humans occurs through contact with infected bodily fluids, causing a “spillover” in species. The virus can also be contracted from another human being when a person is in direct contact with infected blood, vomit or feces during contagious periods, putting health workers in West Africa primarily at risk.
Among other causes, “seasonal droughts, strong winds, thunderstorms, landslides, heat waves, floods and changed rainfall patterns,” are also accused of instigating wildlife migration away from their natural habitat to human proximity. WCS affirms that Ebola outbreaks typically occur after “unusual downpours or droughts in central Africa—a likely result of climate change.” Climate change would in turn amplify food insecurity, and prompt even more remote West African communities to eat virus-carrying animals like bats.
“We already know climate change is weakening crop yields,” explains Kristie Ebi, professor of global health at the University of Washington. “When there’s high food insecurity, how will people go about making sure that they have enough food for their families?”
Thus far, the virus has claimed nearly 1000 lives in West Africa with 1800 currently suffering from the illness. According to reports from the CBC, there are no vaccines or antiviral drugs available to treat the disease, and the mortality rate is estimated at 60 percent.

As the UK cleans up after being lashed by the remnants of Hurricane Bertha, which brought summer flooding and travel disruption, it is also reaping the benefits of a boost to the country’s wind industry brought by the storm, with output hitting near record highs.
Wind power met almost 16 percent of the UK’s power demand on Monday morning, and 13.1 percent of demand over the preceding 24 hours.
The strong performance meant wind power output exceeded coal power—which accounted for 11.3 percent, according to trade body EnergyUK.
It also took output to levels close to the record set during last December when wind energy met 10 percent of electricity demand throughout the month and peaked at 17 percent of demand.
The UK has broken a series of wind records over the past 12 months, and last week new government figures confirmed that 2013 had seen around 15 percent of electricity in the country come from renewables—7.9 percent of which was provided by onshore and offshore wind turbines.
The plentiful supply of wind energy is also helping to pick up the slack this week as French energy companies EDF was forced to shut down four nuclear reactors in the UK.
The reactors are expected to remain closed for eight weeks—after a fault was found in a boiler unit—but National Grid have said the closures should not affect the UK’s energy supply.
It told the Financial Times:
Demand is low at this time of year, and a lot of wind power is being generated right now.
This is an ironic turn of events, with critics of renewables arguing that surges in output caused by weather conditions create problems as renewable energy can not provide a reliable supply.
They argue such sources of energy will also fail to deliver the needed steep emissions reductions as back-up power capacity is still needed.
But the National Grid has said it can manage high levels of variable renewables, and this week’s events have shown that large reactors and generators can also suddenly go offline with no warning.
As recent government figures have show, in 2013 the load factors from onshore and offshore wind actually exceeded or equaled that of gas at nearly 28 percent.

A warming world means a melting cryosphere, which is bad news for species that have evolved to thrive on ice and in snow. Polar bears made depressing history in 2008 when they became the first species to be listed under the U.S. Endangered Species Act solely because of threats from climate change. These sea ice-dwelling carnivores had appeared poised, until Tuesday, to be joined in their global warming-induced regulatory infamy by snow-burrowing wolverines.
Wolverines resemble small bears with bushy tails. They are also known as mountain devils, gluttons, caracajou and skunk bears. They are the largest member of Mustelidae—a carnivorous family of mammals that includes otters, badgers, weasels and ferrets.
While polar bears are a highly visible species, wolverines are enchantingly difficult to spot. This is despite their inhabitation of a broad swath of the Arctic that includes northern portions of Europe, Asia and North America. In North America, most of the populations inhabit Canada and Alaska, although several hundred individuals are estimated to live in the contiguous U.S., mostly in the northern Rocky Mountains. These populations have recently been growing, yet fears over the future of snow in the Lower 48 had federal officials considering adding wolverines to the list of threatened species. On Tuesday, the U.S. Fish & Wildlife Service ruled against the proposed wolverine listing.
Wolverines breed more slowly than most mammals, making them especially vulnerable to breeding disruptions. Once a female reaches the age of three, she normally becomes pregnant every year—but most pregnancies are strategically aborted. That’s because it can take two years or more for the wolverine to forage enough carrion, fruits and berries, and to hunt enough small animals and insects, to build up the energy reserves needed to raise a litter.
Once she is ready to rear a litter, the female adopts a very specific denning strategy—one that will make it difficult for the species to survive in the parts of its territories where snow becomes history. The wolverines dig their dens in deep snow, forming living spaces around logs and rocks that include tunnels, runways and bedsites. There has never been a record of a wolverine denning in anything other than excavated snow. And whenever such a cave starts to melt, the wolverine mother abandons it.
“We have determined that habitat loss due to increasing temperatures and reduced late spring snowpack due to climate change is likely to have a significant negative population-level impact on wolverine populations in the contiguous United States,” U.S. Fish & Wildlife Service (FWS) officials wrote in the proposal to list those populations as threatened.
“In the future, wolverine habitat is likely to be reduced to the point that the wolverine in the contiguous United States is in danger of extinction.”
At least one senior FWS official had been pushing the agency to reject the proposal, arguing that it relies too much on “speculation” about the future effects of climate change. The agency announced on Tuesday that scientists know “too little about the ecology of the wolverine” to list it as threatened or endangered at this time. The ruling “does not close door on this issue,” one official said.
It was this focus on uncertainties that was already making scientists who served on a panel that advised the government on the proposal hot under the collar.
“Myself and the other climate scientists on the panel are disappointed that they’re focusing on the uncertainty, and appear to be ignoring the aspects of science that are much more certain,” said Tim Link, a hydrology professor at the University of Idaho.
Wolverines and polar bears certainly aren’t the only species that will feel the heat as global temperatures rise. Dozens of species of coral might be added to the endangered species list because of the combined effects of disease, warming ocean temperatures and ocean acidification. Like global warming, ocean acidification is caused by carbon dioxide pollution, which is produced by fossil fuel burning and by deforestation.
“From the history of the Endangered Species Act, if you look at the 1,500-plus species that have been listed, the overwhelming majority have not been listed because of climate change,” said Mike Senator, an attorney with Defenders of Wildlife, which had been pressuring the government to list wolverines under the Act.
“It’s been the loss of habitat and other threats—but that’s not entirely surprising, given that climate change has been recognized as a relatively recent issue. We certainly expect that we’ll see more species listed, at least in part, because of climate change.”

They may be little, but those tiny, blood-sucking ticks can cause big problems with your health, including Lyme disease, babesiosis, bartonella, anaplasmosis, Rocky Mountain spotted fever and ehrlichiosis. And the list of tick-related ills just keeps growing. Doctors are now confirming a link between lone star tick bites and cases of severe red meat allergies plaguing patients in Southeastern states. Victims of the odd tick bite side effect have been reported in places like Tennessee, North Carolina and Virginia, but doctors say the problem is spreading up the Eastern Seaboard fast.
According to Robert Valet, MD, assistant professor of medicine at Vanderbilt's Asthma, Sinus and Allergy Program (A.S.A.P.), some patients are developing post-tick-bite allergies to the alpha-gal sugar present in red meat, causing symptoms ranging from diarrhea, difficulty breathing and a drop in blood pressure, to hives and swelling. Some patients are reacting to milk.
"It is not completely understood exactly how the allergy starts," explains Dr. Valet. "The thought is that the tick has the alpha-gal sugar in its gut and introduces it as part of the allergic bite, and that causes the production of the allergy antibody that then cross-reacts to the meat."
Since the alpha-gal is stored in the animal fat, which takes several hours to digest, people with the allergy can go into delayed anaphylactic shock anywhere from four to six hours after eating red meat, making it difficult to diagnose. "It certainly is a big disruption for a lot of people's lives," explains Dr. Valet. "Things like your classic barbecue really become off limits."
Repeated tick bites can raise the level of allergy antibody, so Valet warns people with this allergy to avoid even small quantities of red meat and milk. He also suggests carrying an EpiPen in case a person suffers from an exposure and needs to self-treat.
Whether you're affected by the allergy or not, it's important to practice good tick-avoidance procedures:
Strip down as soon as you step inside.
Remove your clothing, toss it in the washing machine and jump in the shower as soon as you walk inside the house after spending time outdoors. Be sure to then throw your freshly washed clothing into the dryer to kill any lurking ticks.
Get to know your private parts well.
Your groin maintains the perfect humidity for ticks looking to hide in moist, dark areas. The bugs also attach to the back of men's scrotums or women's bikini lines, so be sure to perform a thorough check of your groin and buttocks area at least once a day using a magnifying glass and/or mirror to see more hidden areas.
Treat your shoes.
Although we don't normally recommend chemical treatment, we understand how debilitating tick-borne diseases can be. So rather than applying toxic DEET directly on your skin, try getting a pair of outdoor gardening or workout shoes treated with Insect Shield instead.
Plant some beautyberry bushes.
The leaves of the American beautyberry bush possess tick-repelling qualities, so try working a few into your landscape.
Clean up your woodpile.
Moist, wooded areas are most inviting for ticks. Sunny, dry conditions are not. So keep any woodpiles outside in a spot that gets lots of sun to dry them out faster.

Vaida Lilionyte-Manthos holds a B.A. in History and Anthropology from Vilnius University and Master’s degree in Political Science from West Virginia University (WVU). Originally from Vilnius, Lithuania, she lives in Shepherdstown, West Virginia with her husband David. Mrs. Manthos is pursuing her doctorate in political science, also from WVU.
Growing up in Lithuania I had the impression that environmental problems do not exist in the U.S., or at least they were not as severe as they are in countries like mine that were once occupied by the mighty Soviet Union. I became interested in environmental problems around 1998 when the Lithuanian statesman Valdas Adamkus returned to Lithuania to run for president. Adamkus had worked for U.S. Environmental Protection Agency in the U.S. for many years, and upon coming back to Lithuania he made caring for the environment one of his priorities.
As a teenager I truly believed that America is the perfect country where everyone cares for their environment and uses all their natural resources wisely. However, my opinion changed radically when I came to Western Maryland and then West Virginia to study. I could not understand why some of the streams are so suspiciously orange and without any fish or aquatic plants; but soon I learned that this “suspicious color” comes from the acidic drainage of old coal mines.
I was surprised to learn Appalachia was plagued by a wide range of environmental issues and problems which have never been properly addressed. Failing to learn from history, the region loses its iconic ridges to mountaintop removal strip mining and suffers from a resurgence of black lung disease while disasters keep repeating year after year: from the Upper Big Branch Mine disaster that claimed 29 lives in 2010 to the Elk River chemical spill in 2014 that poisoned the water supply of 300,000 people in nine counties.
I study Political Science at West Virginia University and once I moved to West Virginia I realized how important the coal industry had been to this state, at least in the peoples’ mind and their rhetoric. It seems that any anti-coal speech in WV equates to political suicide. Natalie Tennant, the Democratic nominee for U.S. Senate understands this, and in a recent TV ad, she defends the coal industry by threatening to figuratively cut off power to the White House and accusing Obama of not supporting hard working coal miners. This West Virginia Democrat’s accusation is strange because President Obama, who is pushing for stronger coal-fired power plant regulations, is also a Democrat.
Recent numbers show that the coal industry only employs about 87,000 people, while clean energy industries employ about 360,000 nationwide (Nesbit, US News; June 3, 2014). Additionally, coal only accounted for 18.1 percent of the total domestic power supply in 2013 (US Energy Information Administration; June 2, 2014), meaning that coal is no longer the main energy source in the U.S., and it has cleaner and safer alternatives.
The question arises why people in coal-producing states are so supportive of this industry despite the fact that coal does not create as many jobs as it claims? As a political scientist I could suggest that this support of the coal industry is related with the strong legacy of natural resource extraction or big industries lobbying influential politicians. However, I believe that the tendency to hold onto the past is much stronger than the actual legacy of natural resource extraction.
I was born and raised under the Soviet Union and I remember what quality of life we had then: empty stores, scarcity of necessary goods, only four car models to choose from, and you had to get permission from the local government to buy one! People did not have the right to free speech, were not allowed to travel abroad, nor could they proclaim religion without consequences. Buying a simple one-room (literally, one room; not just one bedroom!) apartment could be a great challenge, and my list could go on and on. Surprisingly, despite all the hardships under Communist rule, some people in Lithuania and other post-communist countries wish the Soviet Union would come back.
Their explanation is simple: under Soviet rule everyone had a job, regardless the pay, quality or necessity of these jobs. The government controlled every aspect of life. People lived in their little low quality apartment and fought for better food in the stores, but their lives were stable. However, the situation changed once Lithuania became an independent country. Many people were not able to adjust to a changing world, learn new skills or adapt to the free market, so they refuse to accept the collapse of the Soviet Union.
In a similar way, I think people in coal-producing states hold on to the memories of the great industries that coal supported and the days when jobs were bountiful. Notwithstanding the lives lost in the coal mines, lungs turned black from coal dust and the air and water polluted by the mines and power plants; coal provided stable jobs and a way of life. And just as many believe that coal made America great, there are still people who believe that the Soviet era was Lithuania’s “Golden Age.”
I believe that just because coal or the Soviet Union did some “good” in the past does not mean that we can ignore the harm. It was only after the fall of the Soviet Union that we understood the harm which had been done by the Communist regime. In a similar way, thanks to science, new technologies, research and environmental organizations, we have a better understanding of the consequences of mining and burning coal, for streams, rivers, for public health and for the climate. We should look forward for new ideas and technologies, which brings real progress, instead of pining for the past.

But economic expansion and population growth, powerfully backed by commercial interests, has for many decades now diminished this experience. Our future generations do not have the opportunity for this experience. It is more of a privilege than everyday act to be able to swim in clean, fresh water. The river Buriganga, lifeline of Dhaka city, the capital of Bangladesh, is such an example. For several years now this river has been maltreated by the residents of Dhaka, leading to it being recognized as a “Black River.”

Today, at the Bosila area of the river, we have demanded it be pollution-free and swimmable throughout the year.

The event on Aug. 9 was chaired by former advisor to the government, activist and advocate Sultana Kamal. She said, “The rivers are controlled and occupied by only a handful of individuals and organizations. They need to be brought under state supervision for the sake of the nation.” Kamal added, “We should all work together to save our rivers, and everyone should act as a Riverkeeper. If we don’t save our rivers, we will not be able to save our city and civilization.”
She was joined by others who echoed similar thoughts. Rasheda K. Chowdhury has called for the attention of the Honorable Prime Minister and suggested speedy action towards saving the river. Syeda Rizwana Hasan, Magsaysay award winner and representing Bangladesh Environment Lawyers Association (BELA), said, “A lot of the pillars used to demarcate the river area are done in a way that seems there is no riverbank. Moreover, there is also lack of political will power. In order to strengthen this, local residents have to play an important role.”
Hasan Masud, popular cultural personality; Gazi Ashraf Lipu, former captain of Bangladesh National Cricket Team; freedom fighter Sultan Ahmed Tipu, Shahjahan Mridha Benu, joint secretary of Bangladesh Poribesh Andolon; and Mohammad Manik Hossain, chairperson of Bosila Primary School, also attended and spoke in support of clean water.
The 13 organizations supporting the event include: Bosila United Club, Bangladesh Poribesh Andolon (BAPA), Bangladesh Environmental Lawyers Association (BELA), WBB Trust, Green Voice, Aachol Trust, Sobuj Pata, Mastul Foundation, Himu Paribohon, Paribartan Chai, NDF, Friends of Rivers and Green Magazine. Residents of Bosila were active participants during the event, which was organized and facilitated by Buriganga Riverkeeper, Sharif Jamil.

Half of newborns in a Brooklyn-based study were exposed in the womb to triclosan, a germ-killing chemical widely used in consumer products, researchers reported Sunday at an annual meeting of chemists.
“Our study suggests that expectant mothers may be highly exposed to these compounds, which have endocrine-disrupting capabilities,” said study coauthor Laura Geer, an environmental health scientist at SUNY-Downstate Medical Center in New York.
In addition to triclosan, about one-quarter of the newborns were exposed to traces of triclocarban, another germ-killing chemical in some bar soaps.
The researchers also reported that pregnant women with higher levels of butylparaben, a cosmetics germ-killing preservative, gave birth to shorter babies than women with lower levels. It’s not clear what health effects, if any, the shorter lengths would have on a child, Geer said. Those findings are preliminary and have not yet been published, so Geer declined to reveal details on the length differences.
“Shifts in birth size may be an indication of endocrine disruption,” she said. “We hope to address the question of adverse health outcomes associated with these chemicals in future research.”
The findings are being presented at the American Chemical Society’s annual meeting in San Francisco. They add to growing debate about the safety of antimicrobial chemicals in consumer products. Triclosan and triclocarban are used in more than 2,000 items, including some toothpastes, liquid soaps, detergents, clothing and toys.
Last year, the U.S. Food and Drug Administration (FDA) announced that antibiotic hand soaps and body washes containing the two chemicals were no more effective than regular soap and water. The FDA is reviewing their safety and possible health effects, with a ruling expected in 2016. Earlier this year, Minnesota became the first state to ban triclosan in some household products.
Studies have reported that triclosan and triclocarban may add to the spread of antibiotic-resistant bacteria, disrupt development of the brain and reproductive system and accumulate in plants and animals. Parabens, identified as estrogen mimics, have been linked to reproductive problems in lab animals, as well as allergies and skin irritation.
In the Brooklyn study, all of the 184 pregnant women tested had traces of triclosan in their urine, while 86 percent had triclocarban, according to the study by Geer and Arizona State University researchers. Umbilical cord blood from 33 of the women was tested. It was the first time triclocarban had been studied in pregnant women and fetuses.
The women had higher levels of the chemicals, on average, than the general U.S. population. Most of the women tested were black.
“If you cut off the source of exposure, eventually triclosan and triclocarban would quickly be diluted out, but the truth is that we have universal use of these chemicals, and therefore also universal exposure,” Rolf Halden, the study’s lead investigator and director of Arizona State’s Center for Environmental Security, said in a statement.
Paul DeLeo, an associate vice president of the American Cleaning Institute, which represents the U.S. cleaning products industry, said the traces found are too small to have any effect.
“Everything around us gets into us. But the levels they are finding are extremely small. There’s a wide margin of safety between these levels and the levels deemed unsafe based on standard toxicology testing,” he said.
However, experts say that standard toxicological tests do not detect many effects, especially ones related to hormone disruption.
Geer said pregnant women who want to reduce their exposures should scan the active ingredients listed on the back of products. “Avoid products labeled ‘antimicrobial,’ since these products likely contain triclosan or triclocarban as active ingredients,” she said.
Big-name manufacturers Proctor & Gamble and Johnson & Johnson have announced they are phasing out triclosan from their products. Many cosmetics companies market paraben-free products.

From our obsession with shark-themed movies like Jaws, to our desire to collect shark teeth at the beach, there's no denying that humans have a fascination with these cartilaginous fish.
But, just how well do you know these creatures? Even if you consider yourself pretty knowledgeable about these species, there’s always something new to learn. Take a look below at 10 cool shark facts that may make you look at these ancient creatures in a different light.
1. The jaws of large sharks are about twice as powerful as the jaws of a lion, and can generate up to 40,000 pounds per square inch of pressure in a single bite.
2. Basking sharks suck in more than 10,000 quarts (or 10,000 large Nalgenes) of plankton filled water in one hour.
3. Sharks have highly tuned inner ears that help them hear their prey from a distance of up to two city blocks away.
4. Some sharks can produce more than 20,000 teeth in their lifetimes.
5. Sharks' eyes are on the sides of their heads, so they have an amazingly wide sightline spanning nearly 360 degrees.
6. The whale shark may live up to 150 years, making it one of the longest-living creatures on Earth.
7. Very few of the more than 350 species of shark—a small minority—are known to attack humans.
8. Some shark species females can be pregnant for up to two years.
9. Sharks have existed almost unchanged for 400 million years—long before the dinosaurs—and yet are at risk from human activities such as fishing.
10. A shark's tooth-shaped scales are designed for dynamic movement but have also been mimicked in biotechnological research for their ability to repel barnacles and algal growth.
