What happens to the environment in the future

I think that the environment will die out, due to the fact that people pollute it more and more, destroy trees, pollute the air, seas and oceans, the climate will also worsen over time.

But everything is not so bad, there is a UN environmental protection program, but even it does not manage to solve the problem of environmental pollution until the end, it is necessary that each person does at least a small job, for example (garbage sorting), everyone can do this, if not everything is for him equal to the future of the earth
