World Environment Day is celebrated on June 5th every year to raise awareness about environmental issues and encourage action to protect the planet. The United Nations Environment Programme (UNEP) started the day in 1973, and more than 100 countries participate. The day provides a platform for people from different backgrounds to share their views and ideas on environmental issues, such as climate change, depletion of natural resources, and pollution. 

The campaign World Environment Day was established in 1972 by the United Nations General Assembly. It is celebrated every year in the month of June on 5th date. It was declared as an annual campaign at the opening of Stockholm Conference on the Human Environment to address the environmental issues in near future.
