Why has Ducks Unlimited started this carbon program?

Global warming will have significant, negative effects on ducks.  In addition, ducks need large expanses of grassland for successful nesting, and there is a waiting list of landowners interested in selling easements to secure grasslands.  With the emergence of new markets for carbon credits, Ducks Unlimited is attempting to raise additional funds for easements through the sale of carbon based on the avoided loss of grassland.
