Climate scientists are not ecosystem scientists.

They study trends in climate, not ecosystems.

The earth is a "plant" dominated ecosystem.

All life at some level depends on plants.

Yet politicians are pushing for CO2 levels far too low to support optimal plant growth.

As humans we should not be trying to stop CO2 levels from rising unless they exceed levels that humans adapt too or plants cannot thrive at. These levels are substantially higher than current levels.
