Happy birthday to my wife, who shares the day with animals everywherer: it's World Animal Day.

Started in Florence Italy in 1931 at a convention of ecologists, World Animal Day has since expanded its focus from its original intent, which was to bring attention to endangered or threatened species. The day is now set aside as a time to reflect on all of the animals we share this world with, and our involvement with them - and to spur action to commemorate that respectful relationship. Half the world's mammals are declining in population and more than a third are probably threatened with extinction, according to an update of of the Red List (an inventory of biodiversity issued by the IUCN), released on October 6, 2008

There are some amazing photos over at The Big Picture.
