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. Also, aim for a development that minimises environmental problems. This is known as sustainable development.
