I sincerely hope, we as a society do not fall into collective nihilism.
What I am thinking about is that, we, as people, who care about the future, do not only need to paint the bleak outlook, if nothing changes, but also the positive alternatives.
A world with degrowth can be a better and more livable one than the one today.
That's why I love the #solarpunk movement so much: Because it presents an alternative vision of the future.
