Which of these methods does not result in conservation of water?

commercial applications receding water table water and ocean conservation water resources and conservation water conservation and irrigation

  1. Using drip irrigation

  2. Recycling of water

  3. Cutting vegetation so that less water is lost by transpiration

  4. Planting more trees

Show answer
Correct Option: C
Explanation:

Conservation is the process in which the resources are used in a sustainable manner without affecting the environment. The water resources can be conserved by using drip irrigation which reduces the wastage of water. Recycling of water will help allow usage of the waste water for non-drinking purposes. Afforestation includes planting of more trees increasing the amount of rainfall. Thus, the correct answer is option C.
