Climate change has always been a thing. The planet has been going thru hot/cold cycles for millions of years.
There is no purpose for any life on earth. The planet survived just fine before life started, it will survive just fine when life is gone. (or until Sol goes super-nova, or whatever it’s called when it expands and engulfs all the planets).
To save earth from what? Climate change?
But then what was the purpose before climate change was a thing?
