World Environment Day is celebrated on 5 June every year, and is the United Nations' principal vehicle for encouraging awareness and action for the protection of the environment. First held in 1974, it has been a flagship campaign for raising awareness on environmental issues emerging from 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, World Environment Day has provided a new theme that major corporations, NGOs, communities, governments and all celebrities worldwide adopt to advocate environmental causes.
The theme for 2020 is "Time for Nature", and will be hosted in Colombia in partnership with Germany.
Colombia is one of the largest “Megadiverse” nations in the world to hold 10% of the planet’s biodiversity. Since it is part of the Amazon rain forest, Colombia ranks first in bird and orchid species diversity and second in plants, butterflies, freshwater fish, and amphibians.
