Some special days like World Water Day are not important just for celebrating the hero behind the day, We need to observe some special days to realize the need of the hour too. World Water Day celebration had started on 22 March 1993 as the United Nations' observance day to spotlight the value of fresh water and taking steps in direction of sustainable management of pure water resources. World Water Day events are organized worldwide on different themes. Organizations arrange educational, musical, lobbying, and theatrical programs. Some target increasing awareness; some focus on fund-raising projects; and some propose new ideas on how to save the water.

World Ozone Day signifies the cause of saving our sky and becoming ozone-friendly. The international day for ozone layer preservation is globally observed every 16 September annually.

International Day of Clean Air on 7th of September not only allows us to appreciate the work done so far for reducing the air pollution and its effects but also reminds us of the need to buck up more.
