I think it’s more important to highlight the human cost, instead of just “life” or “Earth” or “nature”. Yes, they’re destroying life and Earth and nature, but people don’t really care.

Instead, focus on the murder. Climate change is a genocide of the global South - human life near the tropics will be essentially impossible and billions are in eminent danger. The ones that don’t die immediately are going to storm the gates of Fortress Europe and Fortress America for a chance to survive, and they’ll have nothing to lose.
