As I responded to your last comment, there are plenty of observable negatives that outweigh some of the positives of a higher CO2 concentration world.

Greater land areas are being subjected to heatwaves - and plants tend not to like heat stress.

This study shows a slight decline in cereal grains in more places than where they are increasing.



As I've said previously, its too simple to simply state "CO2 is plant food, therefore more CO2 = more plants"

Plants also like water, but they dont all like the same amount, and many would be wiped out by floods, or rising sea levels with increased salinity.

Oh, and by the way, sea levels rose about 1cm/4years or so on average in the last century, this century its expected to be much quicker a few feet doesnt sound like much, but its enough to affect some major global infrastructure and agricultural areas (https://pubmed.ncbi.nlm.nih.gov/22318519/)
