Surely that makes it a bigger problem than inequality between humans.
For those negatively affected by the erosion of rights both represent existential threats. The difference is climate change is an existential threat decades away while the erosion of rights is a threat today. Why would you prioritize a threat that will kill you 30 to 40 years from now when you may die tomorrow from this other, much closer, threat?
I'm personally not affected, but I can absolutely empathize and agree climate change is the lesser threat to those living today. Ideally, we should be able to address both at the same time, but if we have to give priority, then climate change is lower.
