Earth Day is celebrated in commemoration of the beginning of the modern ecological movement all over the world. Earth-Day activity was initiated on 22nd April 1970 by Senator Gaylord Nelson of the USA. He organised the first peaceful rally to draw the attention of the world regarding environmental pollution, dwindling earth’s natural resources, and the industrial activities that were threatening life support systems. The issues raised by senator Nelson then, led to the 1972 United Nation’s Environmental Programme and since then Earth-Day has been celebrated worldwide.The 3R is an excellent way of saving energy and conserving the environment.We can Reuse,Recycle,Reduce and turn off the lights when not in use.
