The whole rain forest carbon credit thing is truly a scam, in the pyramid scheme sense of things. Carbon is neither created nor destroyed, it is only tied up in non-gaseous molecules by having more trees. It depends on people stupidly believing trees never die and the supply of them can be infinitely expanded, neither of which is true. Eventually trees DO die, in 30-100 years for most species, and when they do, they generate just as much gaseous carbon as they tied up while they were alive...nor is the Earth's forest area particularly expandable, just hanging on to whatever there already is can be a challenge.
