Humanity is facing a challenge unlike any we've ever had to confront. We are in an unprecedented period of change.

Each of us now has 2.27 kg (5 lbs) of plastic embedded in our bodies.

Rapid population growth and technological innovation, combined with our lack of understanding about how the natural systems of which we are a part work, have created a mess.

Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater, as well as accidental spills, can contaminate drinking water and harm human health.

Perhaps the whole world is actually a banquet, to which every living thing is invited. First you come as guests: then eventually you're on the menu.

Protecting the biosphere should be our highest priority or else we sicken and die.

Our identity includes our natural world, how we move through it, how we interact with it and how it sustains us.
