I think the issue of population growth is among the factors that contribute to this shortage of food across the globe. the world's population is growing rapidly, and there's increasing pressure on food systems to keep up.You're actually right and that's why I said that it's not an individual task alone. Government must step up into the matter. The good thing is that, government are not sleeping over the issue because in my country, the government has established a number of programs that provide subsidies for farmers as well as funding for research and development.
Many objective factors have already been pointed out here that ultimately lead to food shortages throughout the world. Of course, overpopulation of the planet is also one of these factors. They predict that in the future the problem of food shortages will only worsen. Technological progress saves humanity, but it also destroys it. Thanks to the development of technology, it became possible to process large areas more quickly, but at the same time, people began to quickly change nature to suit their interests, and this has a detrimental effect on nature itself.
The solution may be to create artificial food, which will differ little from natural food. There is a lot of talk about this in the science fiction genre, but at the same time such artificial food, synthesized from non-food products, may well become a reality.
