I found these two extracts of a speech by President Kennedy on 10 June 1963:
Our problems are manmade; therefore, they can be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. Man's reason and spirit have often solved the seemingly unsolvable, and we believe they can do it again.
and
For in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's futures. And we are all mortal.
JFK was talking about about peace but his words seem to apply perfectly to the problem of climate change. How big can world leaders be in Copenhagen in December? Will Man's reason be applied to the problem? We all breathe the same air and we are all mortal.
When put like that it sounds so simple and funny enough if several world leaders started the ball rolling it would probably gather speed but all seem engrossed in their own bit of glory.When MPs are only interested in how much expenses they can swindle without breaking rules or getting caught,Prime Minister,Ministers,party leaders what chance of them saving the world from climate change through pollution of one sort or another.
