As long as we insist that fat people are buried after they die, and make cremation of the obese illegal, then putting the obese into the ground will constitute the much-sought biomass burial. When we bury deceased fat people, it is plain to see that we are removing tons and tons of carbon from the carbon cycle and thus from the atmosphere, and instead sequestering it in the ground.
Not actually accurate, unfortunately. The carbon in a human body never leaves the biosphere. It returns to the atmosphere when the body decays just as efficiently as when the body is burned, just somewhat more slowly. Unless we can develop some way to keep decay from occurring, this won't work.
