Food is obviously something very close to our hearts. That's why food blogs and food critics exist. And we definitely aren't running out of it - I mean, there are new eateries opening up everyday, and it's still cheap.

Well, let's go back to the basics. If the world population is increasing, and everyone is eating food at the same rate, shouldn't it be running out?

It is. We are overharvesting (overshooting) from our food sources, which means that if we continue, they might disappear. And we are putting a strain on other resources needed to produce food, such as water and energy.
