Humans don’t deserve this planet.
Your not wrong, but in our defence before the nuclear testing bomb testing era it was done in ignorance as a result of the coal generated industrial age and human development. I don't think we would be where we are now technology wise without that phase of our history.
Also it has been proven that the planet goes through hot and cold phases, with the ice melting and freezing again. If humans had not built the infrastructures that we are so dependant on like cities roads and all the other amenities we would just adjust and move to other regions not affected by the rising seas. We would not have the agricultural land masses to support our ever rising population.
We have advanced in medicine so much that in about a year we have made a vaccine for the latest pandemic which would have a culled a percentage of us like how previous pandemics have. With people living longer and with no large scale wars also the ability medical science now has we hammer the planets resources. Something has to give and no doubt it will, just hopefully not in our lifetimes.
