We are nowhere near running out of food. Famines are largely political in origin, as are other forms of scarcity, usually resulting from trade embargoes and wars. I would have been worried about energy before we cracked cheap solar power and cheap batteries. At this point we have the technology to power ourselves off the sun even if we lack the political will to migrate to it quickly. Climate change is a danger but I do not believe it's existential unless we really do continue to burn carbon all through the 21st century without migrating to other energy sources and just DGAF. Climate change will cause regional disasters and migrations and political instability but I don't think it's going to cause any more death or suffering than large scale wars. (It may cause large scale wars.) If we did in fact have 1950s levels of global population growth ongoing, we would eventually hit major problems, but that is just not happening. The only place left with high birth rates is Africa and their birth rates are falling like everyone else's as they develop and urbanize.
