The future of the earth
We all know that three-quarters of the earth, about 1.4 billion square kilometers of the planet’s surface, is water. Out of this vast volume, 97.5% is the salty and unusable water of the oceans and seas, only 2.5% of the Earth’s surface water is drinkable and usable that Two-thirds of this amount is also in the Arctic ice and is unavailable. The most important concern for countries by 2030 is the crisis of drought and water shortage. It is evident that one of the most lucrative and creative business areas is to produce drinking water and pay attention to improving environmental conditions.
