The most important thing about water is that it contributes to the preservation of human life. And as water is important in human life, so plants are very important in human life. Just as plants do not live without water, people do not live without trees. Therefore, the importance of water is immense at all times and in every moment. In particular, people can survive for less or more than three or four days without water.Water is another name of life so it is not possible to live without water. Can any human on earth make a single drop of water. Not as far as I know because water is a gift from the creator. Have you ever thought that man can make water? This would be a very dangerous process, no matter how many orders of hydrogen and oxygen. Very well written, best wishes for you.
