Mining Battles: Uranium, Coal and Gold

An impoverished former mining community in Colorado hopes that a proposed uranium mill will bring jobs and prosperity until environmentalists step in to try to stop it. Who gets to decide? Filmmaker Suzan Beraza documents the debate in her new film Uranium Drive In.

Rhinos are killed for their horn. But now in South Africa – they face a new threat — coal. Plans for an open cast coal mine on the border of Hluhluwe-iMfolozi Park, home to the largest population of the once endangered white rhino in the world, may bring economic development but they will also worsen air and water quality and increase poaching and crime. Jeff Barbee reports from South Africa.

The indigenous people in Ecuador's Kimsakocha wetlands, rely on the water here for their livelihood -- agriculture and livestock production. But there is gold under the water and foreign mining companies are out to get it. The local people mount a fierce opposition. "Resistance will not end, we will not give up even if we are in prison," says local community leader Carlos Perez. Constantino de Miguel reports from Ecuador.

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.

Climate Migration

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.

City Planning

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.

Adaptation to Global Water Shortages

Anticipating future water needs, two regions on opposite sides of the world turn to technology for answers. Western Morocco, near the Sahara Desert, is currently facing unprecedented drought and groundwater mismanagement. But an ancient method of gathering moisture from fog is being taught to 13 villages, allowing people to have a level of local control over their most basic need. In Central Valley, California, the food basket of the world uses nearly 80 percent of the entire state's water supply.
