We don’t realize how lucky we are to have clean water whenever we want. A lot of people around the world do not have such an opportunity. Did you know that more than 750 million people on the Earth do not have clean water to drink? Meanwhile, a lot of water is wasted and polluted. In 1993 the United Nations decided to celebrate the World Day for Water. Nowadays a lot of special events are organized in different countries. Their aim is to make people understand how important clean water is for their health, environment and agriculture. Water is essential for our life. We should think about saving it, as the fresh water supplies are limited. We need to keep it clean for ourselves and for future generations.
