Here is reason to save ponds

Professor John Downing, the lake scientist from US has come up with interesting facts about lakes. His research has established that ponds around the globe could absorb as much carbon as the world's oceans. Professor Downing found that constructed ponds and lakes on farmland in the United States bury carbon at 20-50 times the rate at which trees trap carbon. Ponds also take up carbon at a higher rate than larger lakes. In US 90 percent of these water bodies are one hectare or less in area.

Ponds are fast disappearing in many parts if the world as development advances. This new research gives a clear-cut reason for conserving ponds. With deleterious effects of global warming at our doorsteps here is a definite reason to conserve ponds. So go ahead spread the news around. Full details appear in Feb. 15 issue of the journal Global Biogeochemical Cycles in a paper titled, "Sediment organic carbon burial in agriculturally eutrophic impoundments over the last century.”
