And as you may have noted in more than one thread in the last 2-3 years, *I* have never claimed that we can 'stop' any huge, planet-wide process. What we can do is limit our contribution to some of the worse ones. In the process we can ease other problems.

In the meantime, we need to study as carefully as possible what the actual causes are, so that we may both plan and prevent as much as possible.
