World Environment Day (WED) is celebrated on 5 June every year, and is the United Nations’ principal vehicle for encouraging awareness and action for the protection of our environment. First held in 1974,
it has been a flagship campaign for raising awareness on emerging from environmental issues to marine pollution, human overpopulation, and global warming, to sustainable consumption and wildlife crime. World Environment Day has grown to become a global platform for public outreach, with participation from over 143 countries annually. Each year, WED has a new theme that major corporations, NGOs, communities, governments and all celebrities worldwide adopt to advocate environmental causes.
