There is absolutely no basis for saying that Brazilians use less carbon than avatars. It's not scientific whatsoever. It's one of those guilt-ridden Northern liberal thirdworldist fictions.

BTW, there's a lot of Brazilians in SL now. So, all those Brazilian avatars must be offsetting the good those non-avatarized Brazilians accomplish all those years. However, it's all the fault of old white guys in California, they are to blame for everything.
