World leaders from more than 190 countries have convened in Paris during the first two weeks of December for the long-awaited United Nations Climate Change Conference. Will the governments of the world finally pass a binding global treaty aimed at reducing the most dangerous impacts of global warming… or will they fail in this task?

Letters to the Future, a national project involving more than 40 alternative weeklies across the United States, set out to find activists, authors, artists, scientists and others willing to get creative and draft letters to future generations predicting the success or failure of the Paris talks—and what came after. Some participants were optimistic about what is to come; some not so much. We hereby present some of their visions of the future.

Hello? People of the future… Anyone there? It’s your forebears checking in with you from generations ago. We were the stewards of the Earth in 2015—a dicey time for the planet, humankind and life itself. And… well, how’d we do? Anyone still there? Hello.

A gutsy, innovative and tenacious environmental movement arose around the globe back then to try lifting common sense to the highest levels of industry and government. We had made great progress in developing a grassroots consciousness about the suicidal consequences for us (as well as those of you future earthlings) if we didn’t act pronto to stop the reckless industrial pollution that was causing climate change. Our message was straightforward: When you realize you’ve dug yourself into a hole, the very first thing to do is stop digging.

Unfortunately, our grassroots majority was confronted by an elite alliance of narcissistic corporate greedheads and political boneheads. They were determined to deny environmental reality in order to grab more short-term wealth and power for themselves. Centuries before this, some Native American cultures adopted a wise ethos of deciding to take a particular action only after contemplating its impact on the seventh generation of their descendants. In 2015, however, the ethos of the dominant powers was to look no further into the future than the three-month forecast of corporate profits.

As I write this letter to the future, delegations from the nations of our world are gathering to consider a global agreement on steps we can finally take to rein in the looming disaster of global warming. But at this convocation and beyond, will we have the courage for boldness, for choosing people and the planet over short-term profits for the few? The people’s movement is urging the delegates in advance to remember that the opposite of courage is not cowardice, it’s conformity—just going along with the flow. After all, even a dead fish can go with the flow, and if the delegates don’t dare to swim against the corporate current, we’re all dead.

So, did we have the courage to start doing what has to be done? Hello… anyone there?
