No matter that plants can use it, besides we destroying the big green masses to fix that excess from the atmosphere back into organic matter, the excess translate in heat, and they die in drought and scorching conditions.

Lots of pseudoscience to justify things (pd. I'm a former scientist, I don't work at it right now but I see how information is always sweeping to keep people in the blind). There's no truth but the truth, life will thrive on Earth but eventually (at this pace) without us and many other species as we know them. It's all about BALANCE. Every year thousands of species become extinct (NO UNDO FOR THAT), I don't even think we´ll bother to change things before it's late.
what does it change? we know meat industry and transportation pollute the air, we know plastic poison the seas...
we always will look for justification for our own comfort.
