What is our puspose of being here on earth?

Plants help to convert Co2 into fresh O2 for all to breathe for survival.
Small insects clearing up leftovers from larger animals,
Big trees depending on small insects to pollinate it,
And large animals killing one another to control the population of all animals.
So what are we here for, coz we seem to be destroying the Earth well maybe we are here with a purpose, we are given the power to protect and save those endangered animals. So please save the trees and all living things.
So use only what u need coz resources truely are limited its not like we can go shopping anywhere else to get those things.
