World Environment Day is celebrated on June 5 every year in appreciation of nature. The day is marked to highlight the threats to our environment arising due to human actions. The United Nations began celebrating World Environment Day following a campaign in 1974. It was started in order to bring governments, NGOs, communities, corporations and countries under one platform to take collective action to sensitise populations towards our environment. The theme for 2020 World Environment Day is 'Celebrate Biodiversity' and is set to be hosted in Colombia. Colombia holds an astonishing 10 % of the planet’s biodiversity and this day hopes to emphasise this fact. Germany will be the co-partners with Colombia in conducting the event.
