9. Remember the predecessors

We are the first generations to face a catastrophe of the reach, scale and duration of climate change.

But we are far from the first to live under some kind of threat, or to fear what is to come.

I often think of those who were valiant and principled in the death camps of Nazi Germany.

I think of my Latin American neighbours, some of whom braved terrifying migrations, walking across the desert for days to escape death squads, dictatorships and climate catastrophe.

I think of the Indigenous people of the Americas, who already lived through the end of their worlds when their lands were stolen, their populations decimated and colonial domination disrupted their lives and cultures in every possible way.

What it took to persevere under those conditions is almost unimaginable, and also all around us.

Indigenous leadership has mattered tremendously for the climate movement, in specific campaigns and as ongoing testimony that there are other ways to think about time, nature, value, wealth and human roles.

A report that came out this summer demonstrated how powerful and crucial Native leadership has been for the climate movement: "Indigenous resistance has stopped or delayed greenhouse gas pollution equivalent to at least one-quarter of annual US and Canadian emissions."
