The Sacramento-San Joaquin Delta was once one of the lushest marshlands in the state. The peat-rich soil made it an ideal place for some of the state’s first farms to pop up. Today, scientists are hacking their way through thick brush to see if restoring these marshes is a way to reduce carbon dioxide in the air. CO2 is what scientists believe is responsible for global warming.
