Wrong question;
How do we improve the world?
Better question.
1, A law that say you cannot lie and call it science. That would sort out a lot.
2, Stop using food as fuel and thus causing about 20 million deaths per year that would not happen if we stopped making bio-fuel.
lol...good luck with that...as long as man is a selfish, self indulgent fool, that'll never happen...so that'll never happen...
