(I tend to send along an entire NYT article since a paywall kicks in after a number of accesses each month but when the article contains a number of important links--as this one does--it is a good idea to go to the NYT to check them out.)
As the sun rises on Tonle Sap Lake, fishermen head out from floating villages like this one, past half-submerged mangroves and flooded shrub land, to check their nets, much as they have for centuries.
Every year, the lake yields about 300,000 tons of fish, making it one of the world’s most productive freshwater ecosystems. That and the floods that pulse through it in monsoon season, swelling it to as much as five times its dry-season size, have earned the lake the nickname “Cambodia’s beating heart.”
But the Tonle Sap is in trouble — from overfishing to feed a fast-growing population, from the cutting of mangrove forests that shelter young fish, from hydroelectric dams upstream, and from the dry seasons that are expected to grow hotter and longer with climate change.
