The International Day for Biological Diversity is observed on which date?
- A.22 April
- B.22 May
- C.5 June
- D.2 October
Correct answer
Explanation
The correct answer is B, 22 May. The day marks the adoption of the text of the Convention on Biological Diversity and is used each year to draw attention to the loss of species and habitats.
Option A, 22 April, is Earth Day. Option C, 5 June, is World Environment Day, which commemorates the opening of the Stockholm Conference on the human environment in 1972 and is the date candidates most often choose here by mistake. Option D, 2 October, is observed as the International Day of Non-Violence and has no environmental meaning. Important days are a small but certain source of marks in this subject, so learn these four together, and add 21 March for the International Day of Forests and 2 February for World Wetlands Day, which marks the signing of the Ramsar Convention.
