The most impactful single decision one can make in terms of not making things even worse is not reproducing. It is the single most sustainable decision in terms of resource use, pollution and climate change.
The fact that people are voluntarily doing this is good, the presupposed "dangers" of population decline are dangers to the systems that demand infinite endless growth, which I would argue are dangers to people in the first place. Fuck 'em.
Fair enough. I guess I've spent too much time seeing disingenuous calls for "peace" on the internet, mostly by pro-russia shills, with the intent of painting the western support of Ukraine as evil warmongering or something.
We do wish for peace ultimately, but there's a whole lot of violence to happen if it is going to be on Ukrainian terms, because russia does not look like it wants to back down.
