I would like to see more evidence for the theory that everything in nature is getting worse and worse all by itself.
We humans are really good at polluting and destroying nature and everything in it. Our intellect even makes it hard for ourselves and the human race. In the old days without humans there was only nature to take care of itself. Now there are humans messing everything.
Nature allows healthy and well adapted animals to have much offspring by letting them live long. But humans totally messed up this automatic controll mechanism by modern medicin and their intellect. Almost all women live to see the day they become infertile and most people in the western world don't have more then 2,3 kids anyway.
You can't blaim evolution for the stupidities of mankind, how could evolution know what it would lead too? Evolution is just a process.
God on the other hand is an all-knowing being. If he was behind this then he can be blaimed, in my opinion at least.
