This is great news. I still do not understand why rich western countries did not just buy the amazon to protect it though, Im sure we have more money than those companies destroying it.

It will happed, but not like this. I do not expect one super-cure, it is more like thousands smaller battles in one big war against cancer. We have already beaten few types of cancer, survival rates going to 95%+ or even higher, but it is slow hard fight.
