If Venkatesh would have killed the unwanted sea animal, he would have disturbed the food chain that operates in the aquatic ecosystem. There might be some fishes or other larger animals that feed on this unwanted animal. Its killing would have affected the food of the animals surviving on it. Thus, Venkatesh’s act of not killing the unwanted animal is justified and is definitely environment friendly with respect to maintaining the balance of the ecosystem.

Surrounding flora and fauna can be preserved by following some environment friendly steps. Destruction of forests and uncontrolled cutting of trees, reduces the amount of oxygen that is generated by the plants. We need to plant more trees in order to increase the amount of oxygen in the atmosphere. Animals should not be hunted, poached or killed. This result in the destruction of primary and secondary consumers thereby disturbing the balance in food chains.

The more the variety of flora and fauna, the more will be the ecosystem diversity, and consequently, more will be its capacity to keep the energy and the nutrients flowing.
