The best way to ensure that there will be enough aluminum for all future needs is to?

Question

(1)dig more mines and process more aluminum ore

(2)buy more aluminum from other countries and save our own

(3)recycle and reuse aluminum

(4)increased space exploration and search for new sources of aluminum

Answer 1

aluminum will be obsolete in the future

Answer 2

The first three are correct but since you can only select one answer for your test pick the fourth one.

Al is so d**n common that there is no worry about running out of the stuff, it's just a matter of how much energy costs (which we can make pretty low even without needing to destroy the environment).

Answer 3

none of the above.

Aluminum is one of the most common elements around.

The only limiting factor is the huge amount of electricity to produce it from the ore.

"Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon. It makes up about 8% by weight of the Earth’s solid surface."
