Can a growing human population still leave space for wildlife?

No one will protect what they don't care about, and no one will care about what they have never experienced.

The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.

Instead of controlling the environment for the benefit of the population, perhaps we should control the population to ensure the survival of our environment

What humans do over the next 50 years will determine the fate of all life on the planet.

I have gone insane. I won't be talking with you for a while.

I've been circling the wagons down at Times Square, trying to fill up this hole in my soul but nothing fits in there.

I've been touring for so long, I've kind of honed into exactly what I am, I'm an artist so if you like it, you like it, if you don't you don't, you know?

Everything you gather is just one that you can lose.

A circle is the longest distance to same point.

Don't squat with your spurs on.
