What efforts are required to use mineral resources in a planned and sustainable manner ? Explain in three points.

Answer»

Following efforts have to be made to use minerals in a planned and sustainable manner :
(i) Recycling of metals : We should recycle the metal or metal made products to prevent its scarcity. For example : Used steel blade should be sent for recycling, so that the steel can be used again for other purposes.
(ii) Improved technologies need to be evolved : Traditional technologies should be replaced with new and improved technologies, so that the wastages can be minimised.
(iii) Use of substitute or alternative resources : The resources which cannot be recycled or reused should be replaced with the recyclable resources. e.g. Use of green gas instead of coal for cooking purpose
