Bill Gates on TED. Very important speech

Watch Bill Gates amazingly good speech on TED about what challenges we face to save the environment.

In a nutshell. How can we prevent climate change and save billions of lives.

He does not use scare tactics he simply explains the best way to improve the quality of life. Nuclear advocates should be happy that he speaks so well and concisely about the benefits of Nuclear Energy also he mentions twice that "liquid" is a valid competing strategy.
