We must reinvent a future free of blinders so that we can choose from real options.

The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continentsare interconnected. That is our home.

Over and over, the economy has determined the extent of our response, but how much value does it place on breathable air, drinkable water, edible food and stable weather and climate? Surely the economy is the means to a better future, not an end in itself. Surely it must be subordinate to a rich, diverse ecosphere that sustains all life.

If you're not being pessimistic, you're not being very realistic. But I think one must always have hope, and when you have children, of course, you have no choice but to work your tail off to try and protect the future for your children. And that is infused by hope in the end.

I've always been aware of what I eat. There are a lot of options and you have to choose carefully.

I think the real free person in society is one that's disciplined. It's the one that can choose; that is the free one.
