The present situation of earth environment

Earth is our mother.Without earth ,without life.It provides us with enough water,food,sunshine,mineral and so on.I can even say we can only live in the earth .There may isn't any celestial body like earth that our human can live .But there is only one earth in the world,so please protect it ,protect our "mother". Nowadays, the pollution of the Earth is more and more serious and becoming one of the most serious problems of the world.The abysmal lack of fresh water, the desertification, the green house effect and the extinction of creatures are the main issues in environment. With each second that passes, a water crisis takes another step closer to reality. Consumption of fresh water has tripled since 1950; and fresh water is becoming a very scarce resource. Agricultural practices, mainly irrigation, account for 67% of world water consumption. Over one billion people worldwide don?t have access to clean drinking water. So it is incumbent upon all to respect every drop of water and avoid the generation of waste.
