Why vcan't the U.S just make the ozone layer i mean its composed of three oxygen molecules (O3)?

Answer 1

I'm doing my part by flipping my light switches on and off rapidly.

Answer 2

Quantity is the key issue, yes it is just made up of O3, but enough to cover the entire earth, and everytime you send some up there it will eventually break down (the way it protects us from UV rays is by breaking back into O2 and O when struck by radiation) I would imagine the Quantities required would be more than the entire worlds current use of petroleum, and an industry producing O3 just to let it float up into the atmosphere really has no income and would cost hundreds if not millions of billions of dollars

Answer 3

We don't need to replace the ozone in the ozone layer. So long as we stop emitting the chemicals that destroy the ozone layer, it will repair itself in time (~50 years, if I remember correctly).

Answer 4

We could, but it would be absurdly expensive.

For example, we could make ozone and launch it up to the higher atmostphere by a rocket. Since the atmosphere is so large, it would take billions of rockets and quadrillions of dollars, so it isn't worth it.
