Yeah I thought I remembered reading about this vote. I might be misremembering but I thought that there was no concrete plan to address food access and that it was pretty much just a virtue signal vote likely taken so that people who had no intention of feeding anyone could go "What do you mean I want people to starve? We literally backed a vote in the UN to make food access a human right," without ever actually doing anything.

The US sucks for a lot of reasons, chief among them imo definitely our tendency to do literally anything to protect corporate interests. But if I'm remembering this resolution correctly this would have done nothing but give cover to people who had no intention of doing anything on food access.
