I know based upon n science co2 is good, plants need it.

Plants need a lot less of it than there is now. The problem with it at the moment is that it is a greenhouse gas, that is increasing global mean surface temperatures. That disrupts ecosystems, increases droughts and floods, increases wildfires, and changes the suitability of infrastructure and arable land.
