In Cogua, Colombia, some are asking the federal government to take action against the mining and agriculture that threaten the nation’s water supply.

In Carhuaz, Peru, a massive flood caused by climate change has dramatically altered one woman's way of life. Others could face similar destruction.

The Pastoriri Glacier, once a popular ski destination, may have shrunk by 70 percent in the last 48 years. And the culprit appears to be global warming, not tourism.

Colombia's officials say this year marks the worst natural tragedy in their country's history with record rainfall flooding wetlands and isolating small cities.

With most of the tropical glaciers found in the Andes, the quickly vanishing white peaks are becoming a rare sight, and a cause for concern, as some estimate they will vanish within this lifetime.

Colombia is going through one of the most severe rainy seasons in decades. In 12 months of downpours, more than 2.47 million acres of productive land have been flooded.

Lima's population boom, and a lack of infrastructure to support it, has left some residents waiting 40 years for running water.

Called the Costa Verde or, green coast for its once lush vegetation, today the cliff area on Lima's coast is mostly bare.

Lima is one of the cities most immediately threatened by global warming. How will the Peruvian capital respond to decline of its chief source of water as its population grows and demand increases?

A new report by mining giant Greystar reveals plans for a high-altitude mine which would threaten the páramos ecosystem, a water supply for millions of Colombians.

The rise of commercial hunting in Ecuador is disrupting the balance of the Ecuadorian ecosystem.

A recent report estimated that 12 tons of bushmeat is sold every year at the Pompeya market and most of the bushmeat is being hunted by the native Huaorani.

Nearly 50 species of animals are traded each year in the markets and the impact of the large scale poaching is causing problems for the environment. The hunting of large mammals is impacting seed dispersal and allowing for less control on the growth of smaller seed-eating rodents.

Scientists fear Ecuador's rainforest is under threat from the bushmeat trade and illegal commercial hunting by the native Huaorani.
