World Environment Day also known as Eco day is celebrated every year on June 5 in a bid to raise awareness on the role of environment in the society. The World Environment Day was established by the UN General Assembly in 1972 on the first day of the Stockholm Conference on the Human Environment, resulting from discussions on the integration of human interactions and the environment. Two years later, in 1974 the first Eco Day was held with the theme "Only One Earth". This year, the theme for the World Environment Day is 'Biodiversity' and 'Time for Nature'.
World Environment Day is the biggest annual event in the world run by the United Nations to mark the environmental awareness among the people. Its main objective is to raise awareness among people to protect the environment by looking at various problems regarding scorching issues of environment pollution, drastic climatic changes, greenhouse effect, global warming, black whole effect etc, among human beings on the planet Earth. As has been happening every year, Colombia has this year been chosen as the country to host the World Environment Day 2020 event in collaboration with Germany. Last year it had been hosted by China, and the theme had been ‘Beat Air pollution’.
