Is zero a natural or whole number?
'No,' 0 is not a Natural number. Natural numbers, as we know, are positive integers that span from 1 to infinity. However, once we combine 0 with a positive integer like 10, 20, or the other number, we get a number.

Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.
Does infinity exist in nature?
It's infinite, but you never reach or experience the infinity. In a subject like cosmology, there are lots of infinities like that and most people are quite happy with them.

Why are natural numbers not a field?
No, the natural numbers with addition and multiplication as the operations do not form a ring or a field. They don't form a ring because addition does not have inverses in the natural numbers which is a property required for a ring.
