The correct option is D Use of poison to catch fish
Water bodies are the home to many aquatic animals, some of which also eat fish. Not only aquatic animals, but humans as well as other animals that live near the water body eat these fishes.
Use of poison not only pollutes the water but also poisons the fishes. When other animals eat these fishes, they fall ill and may even die. So the use of poison to catch fish should be avoided.
