Those 3 things work, as long as we also include education. I also don't mean work-related education. But education about what we're doing to our planet. What we're doing when we overpopulate the place exponentially.

We hear a lot about invasive species. Humans are actually an invasive species too if we're not careful about the things we do, or how we do them.

If you give everyone water, food, and shelter without the proper education, you can grow our existing problems exponentially which would be catastrophic. So that's the only thing I'd add to what you said.
