Like many river deltas, the Mekong is threatened. Climate change is wreaking havoc, as drought and floods are projected to increase in the coming decade. A reduction in the wetlands not only affect wildlife, but can also threaten the livelihood of the 20 million people who live on the Vietnam side of the Delta. Working with Coca-Cola, the World Wildlife Fund (WWF) has targeted the Mekong as one of six river basins for conservation initiatives.

Rapid population growth and industrialization have exacted huge tolls on the Yangtze. The natural forest cover has fallen by two-thirds over the past 50 years, and resulted in the slippage of over 680 million tons of mud into the river. Coca-Cola and the WWF are trying to reverse this disturbing trend.
