Marine scientist Christopher Clark has spent his career listening in on what he calls “the song of life” in the world’s oceans. In an interview with Yale Environment 360, he explains how these marine habitats are under assault from extreme—but preventable—noise pollution.

Researchers are only beginning to understand the complexities of the microbes in the earth’s soil and the role they play in fostering healthy ecosystems. Now, climate change is threatening to disrupt these microbes and the key functions they provide.

Low gasoline prices and continuing performance issues have slowed the growth of electric car sales. But that has not stymied progress in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight giants like FedEx.

If the world is to have another Green Revolution to feed its soaring population, it must be far more sustainable than the first one. That means finding ways to boost yields with less fertilizer and rethinking the way food is distributed.

In the wake of the Paris climate agreement, developing countries find themselves in need of analysts capable of monitoring their emissions. It’s a complex task, but organizations are stepping in with online courses to train these new green accountants.

Agribusinesses are increasingly using computer databases to enable farmers to grow crops more efficiently and with less environmental impact. Experts hope this data, detailing everything from water use to crop yields, can also help the developing world grow more food.

An overlooked tool in fighting climate change is enhancing biodiversity to maximize the ability of ecosystems to store carbon. Key to that strategy is preserving top predators to control populations of herbivores, whose grazing reduces the amount of CO2 that ecosystems absorb.

Thousands of abandoned gold mines are scattered across South Africa, polluting the water with toxics and filling the air with noxious dust. For the millions of people who live around these derelict sites, the health impacts can be severe.

Massive fires in Indonesia caused by the burning of forests and peatlands for agriculture have shrouded large areas of Southeast Asia in smoke this fall. But analysts say international anger over the fires could finally lead to a reduction in Indonesia’s runaway deforestation.

Small-scale microgrids are increasingly seen as the most promising way to bring electricity to the 1.3 billion people worldwide who currently lack it. In Kenya, an innovative solar company is using microgrids to deliver power to villages deep in the African bush.

The second runner-up in the Yale Environment 360 Video Contest tells the story of the residents of a forest village in central Mozambique who have helped create a tourist destination centered on an elephant population that once wreaked havoc in their community.

Alien rats introduced by ships are decimating populations of birds and other wildlife on islands from the sub-Antarctic to California. Effective programs to eradicate the rats are underway but are encountering opposition from animal activists and some green groups.

The Cross River gorilla population in equatorial Africa has been pushed to the brink of extinction. In a Yale Environment 360 interview, a Nigerian scientist working to save the gorillas describes how local villagers are vital to protecting these apes.

Ethiopia’s plans to build Africa’s largest hydroelectric dam on the Nile have sparked tensions with Egypt, which depends on the river to irrigate its arid land. But after years of tensions, an international agreement to share the Nile’s waters may be in sight.

Kenya’s high-elevation forests are the source for most of the water on which the drought-plagued nation depends. Now, after decades of government-abetted abuse of these regions, a new conservation strategy of working with local communities is showing signs of success.

As “gender advisor” at Conservation International, Kame Westerman seeks to include local women’s perspectives and priorities into the planning of projects in developing countries. This approach, she says, can be critical in determining whether a project succeeds or fails.

To slow global warming, tens of trillions of dollars will need to be spent in the coming decades on renewable energy projects. Some banks and governments are issuing green bonds to fund this transformation, but major questions remain as to whether this financing tool will play a game-changing role.

"Badru’s Story," which documents the work of researchers in Uganda’s Bwindi Impenetrable National Park, is the first-place winner of the Yale Environment 360 Video Contest. Filmmakers Benjamin Drummond and Sara Joy Steele trek along with scientist Badru Mugerwa and his team as they monitor the impact of climate change on one of Africa’s most diverse forests and its extraordinary wildlife.

Vultures are being killed on an unprecedented scale across Africa, with the latest slaughter perpetrated by elephant poachers who poison the scavenging birds so they won’t give away the location of their activities.
