I think one of the ways we could survive this is to radically reform our philosophies and politics. We need to make amends with and reform indigenous rights. LBGTQ+ and women's rights. Abandon capitalism. Accept immigrant and migration. Change our perception of what it means to be happy from endless consumerism to self-actualization and social acceptance. We may have to scale back our modern lives: abandon international tourism, next-day delivery, unlimited energy and clean water, built-in obsolescence, disposable culture etc. Re-design the technology too useful to abandon to be low-impact: as little energy as possible, reliable and interchangeable components, peer-to-peer networks and protocols, etc. Design our lives for near-zero emissions, near-zero waste. Re-learn lost arts like ship building, wood working, forestry, cloth making, foraging, water management, perma-culture, and what it's like to live without plastic, etc.
I believe we have as much capacity for making the environment better as we do for destroying it. It's a matter of will, perception, determination and luck.
I hope we all make it.
