Humans are a life form.
The only purpose of life is to exploit and consume as much resources as possible to reproduce and expand population.
All life forms must do this, else they die out.
Humans have technology, and something they call intelligence.
Technology vastly expands humans ability to consume stuff from our environment, enabling humans to expand their population.
When conditions are right, many life forms can rapidly consume resources, expanding their population, until the resources run out. Think of swarms of locusts, rats/mice.
human intelligence and technology has so far mostly prevented resources from running out for them, so they keep on expanding their population and consuming stuff from the environment, because that's what evolution has made them to do. humans are a swarm on the planet, but with little sign of resources running out to limit us.
humans cannot avoid trashing the planet.
Stopping global warming won't stop us trashing the planet. We'll still be over-farming land, digging disgustingly big and dirty mines, destroying nature to make way for our activities, polluting the place.
This damage is mostly cumulative, we consume much faster than nature can replenish.
The only way there won't be a major ecological catastrophe is for humans to limit their population, which they cannot do themselves. Although china tried that for a bit, did that work out well?
