World people must understand the importance of natural forces and its devastating powers if not used properly. Solar energy is alternative source of many other forms of energy. There are hot water streams in oceans which are responsible for climatic changes. Too much heat generated by heavy industrialization can also drastically change our climate. In non earth quack zones some other form of housings  at least for poor can be possible instead of using cement and steel. This could save lot of money and environment and less carbon dioxide emission. Progress at the cost of environment would harm us in the near future.
