Tone, I have something for you that will put you at ease once and for all.
Remember the time when Dinosaurs became extinct? At that time 95% of all life on earth was destroyed and our planet was almost reduced to a wasteland.
So whenever you feel the urge of blaming human race for this and that, remember this. Our planet has seen damage done to it on such a wide scale that no human EVER even after a million nuclear wars and EVEN after long Nuclear Winters could ever hope to replicate. Our planet has survived through worse than just some tiny human race population and it will survive and over live us a million times fold. What can be wiped out by man, had already been wiped out many times before and was regrown and repopulated. Any damage that we do will primarily affect us (humans) and everything that has existed on earth for millions of years will survive a tiny human race interference.
Have you ever heard of Albert Bierstadt? a 19th century US realist painter? Look up some of his paintings. Not only they are beautiful masterpieces, but they also show the grand design of nature and almost always a tiny small dot for a man.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
