There's a finite supply of helium, and we are running out. Same goes for copper. But the ones that worry me the most are oil and phosphorus.
Yay! someone else who knows about the lack of helium... Buy stocks in helium companies people, it's a by-product of fission which only happens on the sun. Even though it`s the second most abundant element in the universe, the amount on earth is finite.
