Global heating, pollution, overfishing and falling water levels among factors hitting populations, finds IUCN red list study
Nearly a fifth of all threatened freshwater species are affected by climate change, from impacts such as falling water levels, shifting seasons and seawater moving up rivers. Of the assessed species, 3,086 out of 14,898 were at risk of vanishing.
Is there a „humanist nihilism“ movement?
I mean a political and social narrative that the world would be better off without humans?
Is there a party you can vote for, that aims to achieve this goal?
That's the thing with nihilism though, if you beat the drum about it it ceases to be nihilism because it's an individual understanding of oneself in context with the world around you. If a party claims to be a nihilist they're just a power hungry shill, basically.
I believe what you would be wanting is anarcho-ism type movement (:
