Sir: When the earth was created before 4.6 billion years ago, it was very beautiful and the nature was controlling the world. Before 15th century, human beings got busier and started running after how to improve lifestyle and standard of living. Intentionally, they did not want to be against nature and after 18th century people realizing that more sources are required to ease their lives. That was time of inventions but they never thought that these inventions could harm earth’s environment, even they did not think these inventions could be dangerous.Nature is being destroyed slowly. My request to all that save the earth and love nature. RAHMAT BALOCH Kalatuk
