Importance of Conservation :
(i) Mineral resources are being rapidly consumed which takes millions of years to be created and concentrated.
(ii) Mineral resources are finite and nonrenewable.
(iii) Continued extraction of ores leads to increasing costs as mineral extraction comes from greater depths along with deceasing quality.
Three measures to conserve them are :
(i) It should be used in a planned and sustainable manner.
(ii) Improved technology needs to be constantly evolved to allow use of low grade ores at low costs.
(iii) Recycling of metals.
(iv) Using scrap metals.
(v) Finding substitutes.
(vi) Any other relevant point.
