Is metal a renewable resource?
A renewable resource is replenished by natural processes at a rate comparable or faster than its rate of consumption by humans or other users. Renewable Resources include oxygen, fresh water, timber, and biomass. However they can become non-renewable resources if used at a rate greater than the environment’s capacity to replenish them. So the metal comes in Un-Renewable Resources.B’coz it is used at an aquifer at a rate greater than the sustainable recharge. But I thing there is not required for worried about their ends, B’coz metals are not destroyable & they may be remelted from one form to another form & reused. Thanks ! ! !
