World Environment Day is observed every year on:
- A.22 April
- B.5 June
- C.16 September
- D.22 March
Show answer
Correct answer: B. 5 June
Explanation
The correct answer is B, 5 June. The United Nations General Assembly designated this date after the United Nations Conference on the Human Environment held at Stockholm in 1972, and the day has been observed since 1974, each year with a fresh theme and a host country, with the United Nations Environment Programme leading it. Option A is wrong because 22 April is Earth Day, which began as a citizens movement in the United States in 1970 and is not a United Nations observance in origin. Option C is wrong because 16 September is World Ozone Day, the anniversary of the signing of the Montreal Protocol in 1987. Option D is wrong because 22 March is World Water Day, which came out of Agenda 21 of the Rio Earth Summit. Link 5 June to Stockholm and the confusion with Earth Day disappears.
