The entire world is in the cancerous grip of rapidly increasing environmental pollution in its various facets like water pollution, air pollution, soil pollution, and so on. This problem is further supported by global warming and energy crisis. Environmental pollution makes life miserable on this beautiful planet, “The Earth”. This is all because of use of gray chemistry to fulfill different demands of materials with varied applications, such as metallurgy, synthesis of pharmaceuticals and other chemicals, use of volatile organic solvents, polymers, dry cleaning, agriculture, use of detergents, and so on, which creates different kind of pollutions. Men cannot survive without using many of these toxic chemicals to make their life more comfortable even at the cost of their health. Therefore, there is a pressing demand all over the globe to either reduce the use of more toxic materials or to replace them with less toxic or less harmful alternates.
