Obviously any group that has to have funding also needs to get attention to their issues.

The obvious issue is providing clean drinking water and sanitation to every single human being on earth at the cost of little more than one year of the Kyoto treaty.

The Kyoto treaty has an estimated cost of between US$150 and $350 billion a year, starting in 2010.

My suggestion is that we should first work to ensure the Third World has clean drinking water and sanitation.

Wishful thinking is not sound public policy.

We need to invest dramatically in green energy, making solar panels so cheap that everybody wants them. Nobody wanted to buy a computer in 1950, but once they got cheap, everyone bought them.

Money spent on carbon cuts is money we can't use for effective investments in food aid, micronutrients, HIV/AIDS prevention, health and education infrastructure, and clean water and sanitation.

On average, global warming is not going to harm the developing world.

The fact that we're catching more fish per person than we've ever done before doesn't mean that there are not particular places where we've managed fisheries badly.

Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.

Think on a 50-year scale, which is a much more natural time-scale for global warming. The US is right now spending about 200 million dollars annually on research into renewable energy.

Who am I, for God's sake, that I should be kind!

Doubt is an uncomfortable condition, full of unknowns, asking questions but raising possibilities.

What you are must always displease you if you would attain to that which you are not.

Congress shall make no law abridging the freedom of speech or of the press.

I take people very seriously. People are all I take seriously, in fact. Therefore, I have nothing but sympathy for how people behave - and nothing but laughter to console them with.

Conscience is that still, small voice that is sometimes too loud for comfort.

When we met, I never thought in a million years that Will Smith and I would be together.

I just wanted to be a good comic and had no sense of show business, but at some point you want the opportunity to write a show about your life.

I don't set out to make something that is repulsive and that would scare people. I know that some people don't like what I make, and don't find it cute, but that's hard for me to understand.

We cannot change the world alone. To heal ourselves, to restore the earth to life, to create the situations in which freedom can flourish, we must work together in groups.
