Three methods of conservation of minerals are as follows:
- The principle of three Rs—Recycle, Reuse and Reduce—should be followed. It means reducing wastage of resources by recycling and reusing them.
- Use renewable substitutes, wherever possible. For example, using hydroelectricity or solar power to reduce consumption of fossil fuels.
- We need to use minerals judiciously so that we can meet our present needs and at the same time keep enough resources for the growth and development of our future generations.
