Neonicotinoids: The New DDT?

Neonicotinoids are the most widely used insecticides in the world. But they've been linked to the decline of honeybees, which pollinate many food crops. And scientists now say neonicotinoids also harm many terrestrial, aquatic, and marine invertebrates. These pervasive insecticides damage sea urchin DNA, suppress the immune systems of crabs, and affect the tunneling and reproductive behavior of earthworms. They kill off insects that many birds, amphibians, and reptiles rely on for food. "We are witnessing a threat to the productivity of our natural and farmed environment equivalent to that posed by organophosphates or DDT," says Dr. Jean Marc Bonmatin, the lead author of an October 2014 report by the international Task Force on Systemic Pesticides. DDT was banned in 1972 due to both environmental and human health concerns.

Future of Food

Communities and innovators all over the world are creating new sustainable food sources that are resilient to climate change and growing populations. In Madagascar, we see how villagers are closing off marine areas to allow the fish supply to replenish at a natural pace. In San Diego, California, aquaculturists are exploring open ocean farming as a more sustainable model for the fishing industry.

Urban Habitat

Los Angeles is one of the biggest biodiversity hotspots in the world, despite its smog, urban sprawl and snarling freeways. At least 20,000 native and non-native plant and animal species are thriving despite human interference, and in some cases because of it. How can people help make urban habitats more welcoming to non-human urban dwellers?

Sea Level Rising: Living With Water

Louisiana still is learning from Hurricane Katrina. Forecasts are dire for Louisiana to experience the second-highest sea level rise in the world. There is a big movement brewing in New Orleans to build adaptive "resilience zones." In Southeast Louisiana, the native peoples of the Isle de Jean Charles have become the first U.S citizens moving within their homeland displaced by climate change.

Asian Elephants In Peril

Asian elephants, already endangered in Indonesia and Thailand,are threatened further by human encroachment and illegal trade. In Indonesia, just 2,500 Sumatran elephants remain. As their last great forest habitat is being logged to make way for palm oil plantations, elephants are pushed into conflict with local people. In Thailand and Myanmar, an illegal and brutal trade in wild baby elephants is contributing to declining elephant populations.
