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.

This is going to be a difficult few hundred years. No matter what we do, we have to give up some of the advantages of the wealthy Western nations and help out people who are less fortunate. That is the key. I think we can do it if we have more compassion for one another.

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.
