Food is a renewable source; that means that we even though we consume it, more food can be generated.

Duh, right, otherwise how have men been eating foods like fish since the stone age without it running out.

Well, it is renewable, but what most people don’t know is that it can run out. This happens due to overharvesting.

Overharvesting refers to harvesting a renewable source, such as fish, until we are getting lesser and lesser for the same amount of effort invested.

For example, fishermen are finding it harder and harder to catch fishes. That is because we are catching so much fish that we don’t give them time to regenerate.

If this continues, fishes could disappear altogether by 2063. This doesn’t just mean extinction of a species; it also means a loss of food source for 1.2 billion people.
