We know that approx 70 percent of the earth 馃寧 is covered with water 馃挧. If we continue to dispose sewage waste, waste from the factories, household waste, etc, all of the water will not be suitable for drinking. Then all the living beings will die due to thirst. So let us protect earth 馃寧 and ourselves together馃懌 for a better tomorrow.We shall be the guards. Thank you.
