World Environment Day is commemorated each year on June 5th, and started from 1972, which is established by the United Nations General Assembly for raising global awareness to take actions to protect the Nature. The establishment of World Environment Day shows people's the cognition and the attitude to the environmental problem, and expresses our human beings' desire of pursuing the better environment. Every year the United Nations Environment Program proposes a theme, and the 2014 theme of this day will focus on'Small Island and Climate change'and the slogan is “Raise Your Voice Not the Sea Level”.This year's slogan is "To improve environmental quality The development of green".
World Environment Day can be celebrated in lots of ways, for instances, planting trees, doing some recycling, participating the clean-up campaigns and so on. Certainly people can also do something simple, like going to work by bus instead of private cars. I believe if everyone takes environmental actions as a habit, we are doing a big difference for the better environment.
