It was a studie on teenagers where this result is from. I mean the earth will still rotate. But our ecosphere takes havey damage under our current system and I probably don’t have to explain why this is a big problems. Keep on mind that this world we live in is extremely interconceted not only on the social level (like the interconnections between capitalism, stastism, colonialism, Racism, Sexism) but also on the social-ecological level. The short summary of the reason is: alienation of humans from nature, the fact that infinite growth which is required by capitalism is not possible on a finite planet, the focus on power and profit instead of Humans and nature and comodification of the natural world. Social ecology is actually a very own school of thought. I recommend to check out the Lemmy communities on SLRPNK.net and if you want deeper beginners explanation of the topic I recommend andrewisms video on the topic PS: an increasing number in climate scientists and activists (including the IPCC) recognize that we need systemic changes to combat climate change
