People starving come from parts for the world affected by global warming, which unsustainable farming is one of the reasons. Which, in turn, crates mass migration issues. Which, in turn, is a major reason behind massive shift of Overton window and the current world situation we're in.

Every country that has a problem with starvation has huge population growth.

They have at least 2.5% population growth yearly which translates to doubling population in 28 years, while some have as high as 4.5% which means they double every 15-16 years.

If a population has a food problem, why does it double every 15 years?

I don't know which one is worse: to grow soybeans to feed cattle or to use as biodiesel.

What is really upsetting, the speed with which jundles are replaced with oil palm.

Humans have mastered exploitation of everything: the nature, the livestock and other humans.
