How would you reply to someone who argues that we should not worry about the effects that human activities have on natural systems because natural succession will heal the wounds of human activities and restore the balance of nature?

type it, because hand written is sometimes difficult to read. your personal opinion

It is partially true, "life finds a way" but human activities have already made some irreversible damage to the world.

Explanation:

In a Hypotethic scenario in which Humans are extinct nature Will eventually, start succession processes in urban areas and after many years depending on the erosional resistance of the materials nature will erase many of the buildings around the world ( 500 years for metal). Water bodies will eventually decontaminate trough the water cycle and be filled with organisms, contamination due to petrol can also be reverted through natural chemical processes with oxygen.

But human activities like mining are irreversible, for the earth, it is impossible to recover its shape, the materials already extracted and soil nutrients that ran out due to the use of chemicals.

The acceleration of the climate change due to human activities is for sure the biggest wound we have made to the world, this is an irreversible acceleration to a natural process.
