International Biodiversity and Endangered Species Day
The year 2010 has been declared as the International Year for Biodiversity. May 22 is considered as the World Biodiversity Day.
The World Biodiversity Day or the International Day for Biological Day, was created by the United Nations General Assembly in 1993. From its inception until 2000, the celebration has been set every December 29 but was later moved to May 22 so that it will not be overshadowed with the many holidays celebrated during late December.
Meanwhile, the United States celebrates Endangered Species Day from May 21 until May 23 (enacted via a law in 2006). There are many events being held to commemorate these days across the country. Wildlife service agencies and conservation groups will be leading the commemoration.
The Endangered Species Coalition has posted ten things that one can do during these days. You can view them through this link.
Some of the animals that were previously listed to being in the brink of extinction but have now been removed are the bald eagle, American alligator and gray wolf.
