I addressed these questions a few posts back in this very thread.

Studies indicate that rising CO2 concentrations have significantly boosted plant growth. According to a study published in Nature, plants have utilized 30 percent more CO2 since the start of the 20th century, leading to increased plant growth. Another study suggests that global photosynthesis likely increased by 13.5% between 1981 and 2020 due to CO2 fertilization.

When earth was at the lowest CO2 concentration level (180ppm), it was dangerously close to the threshold where plants cannot survive (about 150ppm). We were this close ][ to not existing due to the loss of all plant life.
We're at 400ppm now, which is still extremely low in historic terms. Back when dinosaurs had the planet, CO2 concentration was 1,000-2,000ppm, and they managed to survive despite being the dumb ancestors to birds.
It's preposterous to think dumb dinosaurs could thrive at temperatures and CO2 concentrations way higher, but our species who have figured out how to live in any environment, will fail.
Not a single person will be on their death bed recalling how awful losing a child in a car accident, a brother to diabetes, and now succumbing to cancer was bad, but not nearly the horror of global warming. Not one, ever.
