These people showed up on our behalf and I was moved by their efforts. Maybe, if we all showed up for the really important problems in our world we could see some of the change we want. We would see some of the change we all need.
We need to stop ever more costly and risky extraction from places such as deepwater sites or the Arctic. We need to stop granting subsidies for fossil fuels - something that many of our governments have committed to do but have yet to put into practice.
We march because we know that climate change affects everyone, but its impacts are not equally felt: those who have contributed the least to causing the crisis are hit hardest, here and around the world.
