Earth has always been changing. We may not like it but the earth doesn't give a shet and just keeps on spinning. Life is an absolute miracle. Look at space and how enormous and dark, cold and dead it is. This little rock that we live on has, for a short amount of time provided perfect conditions for life to be possible. But that short time is coming to an end. We are a horribly destructive species that consumes so much and our numbers are multiplying so fast, we really were doomed from the start. And the earth will keep on just a spinning, long after we are all gone and the sun runs out of hydrogen, the earth is scorched and it's oceans boiled away and there will be no trace of us ever even being here. And the earth will still keep on spinning.
