Robert A. Metzger, in his article "Confessions of a CO
2 Composter" (
Wired Magazine), calls his idea Crop Residue Sequestering, or CRS.
A process of sinking crop residue into the depths of the
ocean where
low temperatures will prevent it from
decomposing and releasing
CO2. By trapping CO
2, this process will hopefully slow down
global warming.
(note: this is still an idea and hasn't been actually implemented yet.)
