Global Warming or Climate Change Attitudes if you will

I've been thinking about the arguments about climate change and whether or not human beings are responsible.

Here is my take on the whole thing:

Assume that those who believe that we are responsible for global warming are completely wrong and we are not responsible, but we do what they suggest anyway. What is the end result?

The air is cleaner, people with allergies and asthma and such are not as sickened by the pollution, we cut back on our use of non-renewable natural resources like gas and oil, we create hundreds of thousands of new jobs to produce non-polluting fuels. The air is cleaner, the water is cleaner, and the earth is just a more pleasant place to live.

Now assume that those who believe that we are not responsible for global warming are completely wrong and we are responsible, but we do what they suggest anyway. What is the end result in this case?

The air remains as dirty and polluted as it is now and perhaps becomes worse. People with allergies and asthma and such simply continue to get sick from the polluted air. We continue to to extract non-renewable resources until they are all gone. There are no new jobs in new industries because there are nearly no new industries to supply renewable energy. The air is not cleaner, the water is not cleaner and the world is not a more pleasant place to live. In short we poison ourselves, and maybe destroy humanity and most of the rest of the world.
