when do we celebrate world environment day and why
World Environment Day World Environment Day (WED) occurs on 5 June every year, and is the United Nation's principal vehicle for encouraging worldwide awareness and action for the protection of our environment. First held in 1973, it has been a flagship campaign for raising awareness on emerging environmental issues from marine pollution, human overpopulation, and global warming, to sustainable consumption and wildlife crime. WED 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 celebrities worldwide adopt to advocate environmental causes.
International Day of Peace The International Day of Peace, sometimes unofficially known as World Peace Day, is a United Nations-sanctioned holiday observed annually on 21 September. It is dedicated to world peace, and specifically the absence of war and violence, such as might be occasioned by a temporary ceasefire in a combat zone for humanitarian aid access. The day was first celebrated in 1982, and is kept by many nations, political groups, military groups, and people. In 2013 the day was dedicated by the Secretary-General of the United Nations to peace education, the key preventive means to reduce war sustainably.[1]
