We need to ensure we can sustain life on the earth for as long as possible, and making sure that we can create the energy we need to survive without taking away from the earth, and creating clean energy is the start of this.

We've only got one earth so far, and until we can replace it we have to stop screwing it up. Reversing climate change and educating people about their impact on the environment should be one of our primary goals as a species.
