I just don't really think a lot of this information is from "unbiased" sources. Sorry to break your bubble, but I don't honestly think it has this many beneficial effects. People saying cannabis will "save the human race" have a serious problem, unbiased studies thats are performed correctly are quite rare. Fuel?, Medicine?, building materials?!? seriously, it can replace certain minimal requirements in every one of these fields, but it will not "save" the human race.
