Sadness of Mother Nature

It's too late...
They've proliferate more than I want.
And now, even, they're destroying my body.
Why ? Did I do something wrong to somebody ?
I just wanted to make a being on really high level - something with the most developed physique, very high intelligence, something, which exceed every single life on the sphere body of mine. It was actually an experiment, whose purpose was where are my abilities. So I've made it. That "thing", which is also my curse.
The mankind.
From the very beginning, they looked innocently - yes, some fights and wars between themselves, even if these... "fights" and "wars" were sometimes for nothing and caused by nothing... If they want to kill each other so much, then why not. Of course, I've stood and I'll stand these streams, not if even rivers of blood from their veins. Let them do, what they think is necessary. When they left me alone, I was fine with this.
Yes, they used to be like this. They exploited my sources well. But now, from few hundreds years on, they've ravaged my skin and polluted air, something I gave all the beings to survive -  they don't appreciate anything ! Those heartless pigs !
But I've tried to eliminate them, so many times I've tried - but they are still just like ants, like some nuisance, parasite, hungry for every piece of the space on me !
And I feel tired. I am not able to regenerate so fast. Their weapons are so strong,  yet I'll fight against them till the very end.
I've made a huge mistake, but now, I'm afraid, it's too late...
