Focus on progress that has been made, solutions to the climate crisis have been growing exponentially over the past decade. And it's not a binary issue of everything is sunshine and rainbows vs we're all fucked. There's more of a spectrum. Also remember the past environmental successes we've had with like acid rain, the ozone layer, leaded gas, mercury pollution. We've come a long way.

Making any progress, no matter how small makes the future just that much better than it otherwise would be. Yes, systemic changes out of the control of anyone on Lemmy are needed, but if say every person on Lemmy worked towards reducing their own environmental impacts that could have huge ripple effects in the economy of the green transition. Just plan out pragmatically/realistically how much time, mental energy, and resources are worth it to you.

A lot things that individuals can do to help with the climate crisis often also have personal benefits like long term financial savings, less pollution exposure, healthier plant-based diets, etc.
