Incidentally, the creationists that I've encountered diligently deny that our Earth's climate is being altered by people. This point of view and teaching is in absolutely no one's best interest. Here's hoping we can work together and preserve the Earth, for us - us humans.

The thing about a theory in science is it allows you make predictions. Evolutionary theory allows us to predict what apples will taste good next harvest.

I abandoned my religious teachings after I read the Bible twice - cover to cover. It took me a couple of years.

We need them. We need scientifically literate voters and taxpayers for the future.

There are two ways to be rich: to have more or need less. It's estimated that we squander about 30 percent of our energy leaving the lights on, the refrigerator door open, and so on. Then there is the enormous amount of food that we expend huge amounts of energy to raise and then throw away.
