</font><font color="blue" class="small">( When I was in grade school in the 1970's we were told the coming ICE AGE would kill humans off. What changed? We were also told in the late 1990's that the "government" had done away with business cycles, only up not down.
Seems to me the world revolves on cycles. )</font>
The Earth does work in cycles: spring, summer, fall and winter. We have droughts and floods, blizzards and heat waves. Always have, always will. Economics will always work in cycles; there will always be booms, busts and corrections.
Note that the vast majority of studies predicting ice ages and global warming are government funded. If no impending crisis is found, the funding stops. So these government funded “scientists” have every incentive to find a crisis of some sort, or some reason that will call for additional study, hence additional funding.
There are true environmentalists, and there are those who claim to be environmentalists, but actually have an anti-capitalist political agenda and use the environmental movement as a conduit for this agenda. These are the people that Bob is referring to. I don’t know anyone who actually desires to pollute the air and water, so the environmental movement is the perfect place for those with an anti-capitalist agenda to get their message out to the general public. The “true” environmentalists need to purge these anti-capitalists from their ranks, because the solutions to our environmental and energy usage issues rest with the high-tech private sector of our economy, not with government mandated match-box cars.
