Metals

What will happen to the world if there are no more metals?
1)There will be no cars , no satellite , no phones , no computers , no building , no electricity. The world would be very dark and cold. Meaningless.


Is it important to recycle metal?
2)Yes this is because aluminum are often used in can drinks , imagine if there was no recycling of metal. And have to extract on the rocks just to produce a can drinks. And in future everything would be gone.And there won't be any metals. Because metals resources are limited in this world. And recycling reduce pollution.


Thus what are the reasons to recycling metals? Isn't it easier to obtain metals through it's orginal form through extraction of metal?
3)The reason is that because ore are limited , the more you mine the lesser metal in future we have. Which means no more can drinks , no more electricity , no more new car and transport like the train. Is not easy to extract. Singapore has no resource thus have to be shipped over for quite long period thus price increases.


4)People thinks recycling is safe but recycling is a very slow harmful to the earth but still harmful. Pollution are produced when it is recycled during the process which include chemical stews when breaking down different products. So many different factories must be builded for recycling metals which cause even more pollution and energy consumption.
