It is now abundantly clear that we have at our fingertips all of the tools we need to solve the climate crisis. The only missing ingredient is collective will.

Properly understood, the climate crisis is an unparalleled opportunity to finally and effectively address many persistent causes of suffering and misery that have long been neglected, and to transform the prospects of future generations, giving them a chance to live healthier, more prosperous lives as they continue their pursuit of happiness.

Our Choice gathers in one place all of the most effective solutions that are available now and that, together, will solve this crisis. It is meant to depoliticize the issue as much as possible and inspire readers to take action—not only on an individual basis but as participants in the political processes by which every country, and the world as a whole, makes the choice that now confronts us.

There is an old African proverb that says, "If you want to go quickly, go alone; if you want to go far, go together."

We have to go far, quickly.

We can solve the climate crisis. It will be hard, to be sure, but if we can make the choice to solve it, I have no doubt whatsoever that we can and will succeed.
