Scientists and supercomputers have amplified our ability to look ahead. For decades, experts have warned us that human numbers, technology, hyper-consumption and a global economy are altering the chemical, geological, and biological properties of the biosphere.

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.

There are more humans than all of the rabbits on earth. There are more of us than all the wildebeests, than all the rats, than all the mice. We are the most numerous mammal on the planet. But because we're not like rabbits or rats or mice, we have technology, we have a consumptive appetite, we have a global economy.

So, there is enormous instability in the global economy with a shift of winners and losers.

Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.

This new global economy, it's all based on the sea routes.
