> Say a square kilometer of denuded farmland is converted to forest. In principle I'd agree, but: again this really depends on soil type and history and surroundings and type of forrest. The forrest won't be bad, but depending on factors as far as sequestration goes (and biodiversity as well to some extent) it could actually be better to turn the farmland into a meadow. Those don't necessarily have to be wetlands to sequester more carbon over the course of years. Just like for every new square kilometer converted to whatever, it might actually be worth more to try and preserve one square kilometer of rainforrest instead of having it cut down.
