How long can a landmine stay active after it has been laid?
Landmines can remain active more than 50 years after they are planted in the ground. For this reason, there is a growing worldwide effort to rid the world of landmines. To do this, we must first locate the millions of landmines that are still buried in dozens of countries around the world.

How long does it take for land to recover from mining?
Even with differing mixes of toxic metals and different treatment practices used to control the pollution at each site, the studies documented successful recovery to near natural conditions within 10 to 15 years.
Will mining run out?
The reserves of some rare earth minerals used in electronics, medical equipment and renewable energy could run out in less than 100 years. Rare earth minerals are naturally occurring resources, which cannot be recreated or replaced. Some are present in only very small quantities in the Earth’s crust.
