We use a lot of water in our daily for drinking, cooking, washing and sanitary purposes. Today we are facing a water shortage. It has been estimated that by 2050 almost a third of the people on our planet will not have access to this resource.
You may have observed that when you leave an ice cube outside, it starts to melt and turn into water. This is because the temperature outside your freezer is much higher. Imagine then what the effect of global warming will be to those places that are full of ice. One such place is Greenland, which has lost 1500 cubic kilometres between the year 2000 and 2008.
Almost everything we use today - plastics, medicines, synthetic fabrics - is made by some chemical process or the other.
