Environment:The Molecular Universe —— Mother Earth: A Chemical Laboratory

There is no modern civilization without oil, natural gas and electricity. Human's unlimited exploitation of these sources has resulted in many serious problems. In order to solve these problems, chemists and engineers have turned to new energies, such as wind power, hydrogen and solar energy. With the extensive application of all these new energies, people will get products from cleaner and more environmentally friendly energies.
