? CO2 is removed from the atmosphere by various natural processes. The
obvious way to reduce CO2 would be to create less than is removed. As for
burning fossil fuels it does seem sensible to look for alternatives even
with out global warming they will run out.

You don't appear to understand the magnitude of the problem? Comparing CO2
levels to previous affects of human agriculture is ridiculous.

This is nonsense there are alternatives to fossil fuels. Nuclear, less car
use etc.

You are right a world solution is required.
