RE: Will humans go extinct in 100 years?
If you look at what humans have achieved up until the 1800's and to what they have done up until now, I shudder to think what will happen in the next 100 years.
I firmly believe that there will be a major collapse of the food chain in the near future. This will in turn cause mass starvation for humans - mainly in the 3rd world countries. In our misery, we will probably wake up and act more responsibly... but the damage is done and will probably take a very long time for nature to recover. Luckily, we have the knowledge and experience to rejuvenate endangered species so this may help in the long run. We just need to work together - and that includes greedy corporations.
