Which of the following is an example of sustainable use of natural resources? question 21 options: 1) clear-cutting a forest 2) continuously strip mining coal deposits in an area 3) harvesting huge populations of fish from a fishing shoal 4) planting multiple crops together on a field and harvesting them at different times

Planting multiple crops  on a field and harvesting their products  at different times is example of sustainable use of natural resources.

Explanation:

Sustainable use of natural resources refers to the use of natural components present in biological diversity at such a rate that the natural resource doesn’t get depleted. Also, the goal of the sustainable use of natural resources is to safeguard the natural resources for the current and future generations.

So planting multiple crops and harvesting them at different stages is a sustainable process. During this process, the natural resources are not over-utilised rather it is replenished back into the environment. This process also produces more yield from a limited area of farmland. For example, we can do banana plantation along with coconut farming. Here we can harvest both banana products and coconut products.
