15 Most Surprising Trends for 2017
By Mary Hoff
What should we be thinking about when we think about the future of biodiversity, conservation and the environment? An international team of experts in horizon scanning, science communication and conservation recently asked that question as participants in the eighth annual Horizon Scan of Emerging Issues for Global Conservation and Biological Diversity. The answers they came up, just published in the scientific journal Trends in Ecology & Evolution and summarized below, portend both risks and opportunities for species and ecosystems around the world.
"Our aim has been to focus attention and stimulate debate about these subjects, potentially leading to new research foci, policy developments or business innovations," the authors wrote in introducing their list of top trends to watch in 2017. "These responses should help facilitate better-informed forward-planning."
1. Altering Coral Bacteria
Around the world, coral reefs are bleaching and dying as ocean temperatures warm beyond those tolerated by bacteria that live in partnership with the corals. Scientists are eyeing the option of replacing bacteria forced out by heat with other strains more tolerant of the new temperatures—either naturally occurring or genetically engineered. Although the practice holds promise for rescuing or resurrecting damaged reefs, there are concerns about unintended consequences such as introduction of disease or disruption of ecosystems.
2. Underwater Robots Meet Invasive Species
If you think getting rid of invasive species on land is a challenge, you haven't tried doing it in the depths of the ocean. Robots that can crawl across the seafloor dispatching invaders with poisons or electric shock are being investigated as a potential tool for combating such species. The technology is now being tested to control crown-of-thorns starfish, which have devastated Great Barrier Reef corals in recent years and invasive lionfish, which are competing with native species in the Caribbean Sea.
3. Electronic Noses
The technology behind electronic sensors that detect odors has advanced markedly in recent years, leading biologists to ponder applications to conservation. Possibilities include using the devices to sniff out illegally traded wildlife at checkpoints along transportation routes and to detect the presence of DNA from rare species in the environment.
4. Blight of the Bumblebees
We tend to think of pollinating insects as our ecological friends, but in the wrong place nonnative bees can spell trouble instead by competing with native insects, promoting reproduction in nonnative plants and potentially spreading disease. And they're doing just that, thanks to people who transport them internationally for plant-pollination purposes. Out-of-place bumblebees are already spreading through New Zealand, Japan and southern South America, and there is concern they could do the same in Australia, Brazil, Uruguay, China, South Africa and Namibia.
5. Microbes Meet Agriculture
Select bacteria and fungi are emerging as potential agricultural allies for their ability to help kick back pests or stimulate growth in crops. As research advances in this area, questions are being raised about potential implications for nontarget species, ecosystems, soils and more.

Two years ago—long before coal became one of the most dominant and controversial symbols of the 2016 presidential election—Bloomberg Philanthropies approached production company RadicalMedia with the idea of creating a documentary exploring the U.S. coal mining industry. Last spring, they brought on Emmy-nominated director Michael Bonfiglio, tasked with forging a compelling story out of the multitudes of facts, statistics and narratives underlying the declining industry.
The Sierra Club released a new analysis Friday that found that transitioning all 1,400+ U.S. Conference of Mayors member-cities to 100 percent clean and renewable electricity will significantly reduce electric sector carbon pollution nationwide and help the U.S. towards meeting the goals of the Paris climate agreement.
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."

Seismic airguns exploding in the ocean in search for oil and gas have devastating impacts on zooplankton, which are critical food sources for marine mammals, according to a new study in Nature. The blasting decimates one of the ocean's most vital groups of organisms over huge areas and may disrupt entire ecosystems.
And this devastating news comes on the heels of the National Marine Fisheries Service's proposal to authorize more than 90,000 miles of active seismic blasting. Based on the results of this study, the affected area would be approximately 135,000 square miles.

Is coconut oil:
- good for you
- bad for you
- neither good nor bad
- scientists don't know
The subject of this question is the source of a disagreement. Initially, the question was thought to be settled decades ago, when scientist Ancel Keys declared all saturated fats unhealthy. Coconut oil, which is solid at room temperature, is a saturated fat.
The U.S. Fish and Wildlife Service removed grizzly bears in the Greater Yellowstone region on Thursday from the Endangered Species List. The decision comes despite serious concerns in the scientific community about a declining, isolated population with diminishing food resources and record-high mortalities, as well as strong opposition from an unprecedented number of Tribal Nations.

ArborGen Corporation, a multinational conglomerate and leading supplier of seedlings for commercial forestry applications, has submitted an approval request to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service to deregulate and widely distribute a eucalyptus tree genetically engineered (GE) to be freeze tolerant. This modification will allow this GE variety to be grown in the U.S. Southeast. The reason this non-native and highly invasive tree has been artificially created to grow outside of its tropical environment is to greatly expand production capacity for the highly controversial woody biomass industry.
