What's the Problem?
Food shortages have always been a big problem in the world. With uncontrollable factors such as the weather, farmers have a hard time knowing when it is the appropriate time to grow their crops to feed people all over the world.
Medical advances and public health services cause the world's growing population to have longer life spans and more births. This makes it even harder to find food supply that will feed most of the world. The most fertile lands are becoming scarce, which leaves farmers no other choice but to cultivate on poorer, less fertile lands. Feeding the world is a huge issue.
