Earth is a beautiful living planet in the Universe and the common habitat of more than 7 billion human population and millions of species of biodiversity. Our Earth provides us with food, shelter and most of our requirements.
Despite unavoidable free services provided by the earth to humans, we are not able to pay off her kindness to us. Rather we humans are being cruel to our Earth with our selfish activities. Mahatma Gandhi said, "Earth provides enough to satisfy every man's needs, but not every man's greed."
