Neonics: Driving Declines in Biodiversity
British bumblebee ecologist Dr. David Goulson, professor of biology at U.K.'s University of Sussex, discusses the impact of neonicotinoid pesticides on biodiversity declines in farmlands. His pioneering research on the impact of neonicotinoid exposure on bumblebees shows that treated nests produce 85 percent less new queens than control nests.
"We essentially have somehow been railroaded by agrochemical companies into relying entirely on their products," he says. "We depend on bees to pollinate our crops and worms and other organisms that live in the soil to keep the soil healthy. If we wipe them all out, then ultimately we will wipe ourselves out."
This documentary explores why desert tortoises are a threatened species and how people can change the environment through seemingly innocent actions.
“Vanishing Coral” presents the personal story of scientists and naturalists who are working with local communities to protect coral reefs that are being destroyed by warming seas, pollution, and destructive fishing practices.
Elephants have lived in the savannas and forests of Africa for more than two million years. They are the largest land animals on Earth – and one of the most intelligent. They feel emotions like grief and joy. Can they even survive in the wild anymore?
The cost of climate change is rising and its consequences are increasingly threatening our national security.

Desert tortoises are a threatened species. Habitat destruction, diseases and other factors have reduced their numbers by up to 90 percent. Now flocks of ravens, that often live off human trash, are eating baby tortoises, reducing the odds of tortoise survival as a species. This documentary explores that impact, pointing out how people can change the environment through seemingly innocent actions.
Every twenty minutes an elephant is killed to feed an insatiable demand for ivory. African elephants may be gone in as little as ten years. Behind the slaughter are the most dangerous groups in the world – organized crime syndicates, insurgents and terrorists. Ivory buys guns and ammunition for Uganda's Lord’s Resistance Army and Sudan's Janjaweed, both linked to mass atrocities and supports al Shabaab, the al Qaeda affiliate behind the attacks on Kenya’s Westgate Mall and Garissa University.
“Vanishing Coral” presents the personal story of scientists and naturalists who are working with local communities to protect coral reefs that are being destroyed by warming seas, pollution, and destructive fishing practices. Featured in the documentary is the President of the Biosphere 2 Foundation Abigail Alling, marine biologist and coral expert Phil Dustan, captain of the Mir research sailing vessel Mark Van Thillo, and Nono Suparno, a leading conservationist in Bali.
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.
Populations are dramatically shifting as climate change drives migration. Droughts and floods are driving many people away from their rural, farming communities into big cities. We see how this is manifesting in Mongolia and examine the factors leading to the new community of Haitian people living in limbo at the border between Mexico and the U.S.
Two cities, San Francisco and Freetown, brace for climate change using vastly different methodologies. San Francisco's developers are building expensive real estate on floodplains as officials try to heed expert projections on future sea levels. On the other side of the world, a deadly mudslide caused by torrential rains and deforestation in Sierra Leone shows the consequences of city planning that doesn't take climate change into account.
