How could a resource become limited?

Answer 1

Although we think of some resources as renewable, resources are always finite and limited.

A resource that we think of as renewable could become one that we think of as non-renewable or limited if a tragedy happened. For instance, beef is a renewable resource, because more cattle are born every year. But if a disease wiped out almost all cows worldwide, then the species would be endangered, and the idea and cost of having beef at a meal would change completely... we would start seeing that resource as a limited resource rather than the infinite supply that we sometimes imagine now.

A supply could also become sharply limited if it is overused, or our technology isn't good enough to gain access to something, even if it still exists somewhere.

Answer 2

limited it can be change or made a lot of time and unlimited is the thing we can always see or get
