You see, the Greenhouse Effect is a direct result of burning fossil or old carbon fuels.

Making ethanol from corn is a good thing if you want to offset fossil fuels from overseas. On the greenhouse gas side of things, it is not clear if corn, as grown today, is a good thing. We just don't know yet, but it appears to be a mildly good thing.

It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.

Growing hemp as nature designed it is vital to our urgent need to reduce greenhouse gases and ensure the survival of our planet.

One SF prediction that I would like very much to see: Get solar collectors launched to beam energy back home, and get away from fossil fuels.

Even if we didn't have greenhouse gases, were going to have to move away from fossil fuels, as we're going to run out. They're finite, whereas solar and wind are infinite.
