You can look for the information you seek yourself.
When anyone say's something which I'm not sure about, I will look for it to see what I can find out about it.
Whats wrong with you doing the same?
There are also no known facts in this debate. Only opinion on what the facts will be.
My opinion has taken 15 years of information gathering from books, TV documentaries, Web sites, Newspapers, University lectures and Radio shows. I could'nt start to begin to give you reference's to where I get each part of my point of view from. But I can guide you in the right direction to what sort of information you should be looking for to be able to work out the possible scinarios created from mans past and present actions on our future generations planet.
I'm still not sure which points you are struggling on though.
Also where's the links for your information?
