It's not an if - we're going to have to change. Oil is simply going to be gone.
We should be able to support our own economy within our own borders.
Practically every environmental problem we have can be traced to our addiction to fossil fuels, primarily oil.
We don't have to sacrifice a strong economy for a healthy environment.
Whatever we'll be forced to do later, we should be doing now.
The people of the future will say, 'meat-eaters!' in disgust and regard us in the same way that we regard cannibals and cannibalism.
