The amount of water on the planet does not change, only its quality.

People have to realize that the air we breathe and the water we drink come from the ocean and will go back to the ocean one way or another, no matter how far away we may be from it. It's a perpetual cycle.

We have to have more consideration for people who have lesser means than we do. It is a problem of survival.

There is no question that a very large number of people have to move; you cannot live where the water comes over you. I have not heard one suggestion on how we are going to move one hundred million people out of low-lying areas and what countries would be willing to accept them.

What do we expect the climate to do? How will it affect people? And how can we protect people from hardship? We should be willing to face the facts that things may not go very well.

Fresh water is like a fossil fuel; we should not waste it.

More and more students are playing it safe and not taking any risks. You might not succeed, but that's just part of the game.
