For a long time the laws of Canada have explicitly banned gambling in any form. This may be the reason why the country does not have so many gambling establishments as the USA - but their quality surely makes up for the quantity. The first Canadian casino was opened in Dawson City, Yukon, in 1972 - it was the first one after gambling has been banned in the country in 1892. The Diamond Tooth Gertie's Gambling Casino did not operate for long, though. The first permanent commercial casino was opened in 1989, and it was the first of many - there are currently 75 casinos operating on Canadian soil.

“Wombats are Australian marsupials; they are short-legged, muscular quadrupeds, approximately 1 metre (39 in) in length with a short, stubby tail. They are adaptable in their habitat tolerances, and are found in forested, mountainous, and heathland areas of south-eastern Australia, including Tasmania, as well as an isolated patch of about 300 ha in Epping Forest National Park in central Queensland”. – Wikipedia

Wildlife photographer Danté Fenolio has headed into areas untouched by sunlight – deep seas, caves and underground – and found creatures that are exploding with colour. Here: The golden harlequin toad has vanished from the wild, and only a small number live on in captivity. A fungus caused them, and many other amphibians, to die out in their home in Central America.
