World environment day was designed by the UN General Assembly in 1972 on the first day of the United Nations Conference on the Human Environment. Since 1974 the World Environment Day became the global celebration with the theme “Only One Earth”.
This year the theme of World Environment Day 2020 is “Celebrate Biodiversity”.
World Environment Day 2020 will focus on Biodiversity and will be hosted in Colombia in partnership with Germany.
Why should we care about Biodiversity?
Biodiversity is the variation of Earth’s terrestrial, freshwater, and marine species, as well as their habitats. Biodiversity is vital to the survival of all life on earth and is also the cornerstone for the goods and services of the environment that allow human societies to thrive. Biodiversity provides us with food, water, and resources as well as services such as climate control, pollination, flood mitigation, and cycling of nutrients.
Ecosystems are relying on all parts from the smallest bacteria to the largest vertebrate. It’s all interconnected. Some are producing oxygen that others are breathing. Some provide food for larger species, which in turn become prey to even larger species. Every living organism has a role to play in the maintenance of balance.
