I'm not physically intimidated by anyone on this earth.

Water covers about 70 percent of the Earth's surface. Of this total, only about 2.5 percent is fresh water, and most of this is frozen in the ice caps of Antarctica and Greenland, in soil moisture, or in deep aquifers not readily accessible for human use.

I feel very passionately that we need to take care of the planet and everything on it. Whether it's saving the Amazon or just being kind to those around you, we need to take care of each other and Mother Earth.

The nice thing about asteroids is that once you've found them, and once you have a good solid orbit on them, you can predict a hundred years ahead of time whether there is a likelihood of an impact with Earth.

One thing I can't prove, but I firmly believe is that two men were put on this earth - one threw a punch and a third guy came over and watched. And that happened before anybody ever threw or kicked a ball.
