Now you are on to something. All environmental wacko theory is built on the idea that there are too many people. The craziest is the idea that the earth can only support 1M people. Do the math on how many of us need to go to make that a reality.
I think you are making a too logical assumption. :)
It should be “All environmental wacko theory is built on the idea that there are too many OF YOU people.”
The ones stating the theory don't factor themselves into what they are saying
I have heard the figure of 1 billion, if they are going to have American and European standard of living.
