Definition of natural numbers is the same as non-negative numbers, so of course 0 is a natural number.

In some countries, zero is neither positive nor negative. But in others, it is both positive and negative. So saying the set of natural number is the same as non-negative [integers] doesn't really help. (Also, obviously not everyone would even agree that with that definition regardless of whether zero is negative.)

But -0 is also 0, so it can't be natural number.
