Images of Wetlands from Space
The Earth's wetlands are home to some of the most fragile and diverse ecosystems on the planet, and they're under constant threat from human agriculture, pollution, and settlement.
This month the European Space Agency began a program to map 50 wetland areas around the Earth from space to help keep track of their health. ESA's Envisat is able to tell the difference between dry and waterlogged areas, and will be able to provide annual data about how various wetlands change throughout the seasons.
