Exactly what is it about CO2, a plant food, that scares you so much? You do realize that green plants react to increased CO2 percentage with stronger growth?

You're the one calling me a "doomer"?

Plants and humans both love water, but you can still drown.

Where do i even begin to respond to this?

Plants growing slightly faster does not mitigate the many consequences of increased CO2.

Nitrate is a plant food too, doesn't mean it's not killing large parts of the ocean.
