there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years (in fact, over 99% of all species that ever existed are now extinct!). given these facts, why do we care if human activity is driving other species extinct as we grow?

This is because humans are causing species to go extinct at a faster rate than the normal rate.

Explanation:

It is documented that there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years. Some may say even if nothing is done there would still be extinction of this species which is true.

We care if human activity is driving other species extinct as we grow because humans are causing species to go extinct at a faster rate than the normal rate.
