This huge male orangutan is having a right old laugh as he squints his eyes and shows his huge teeth. The orangutan, called Bimbo, was relaxing on a platform around 5m high in his enclosure when he broke out into a laugh. But his happy smile soon disappeared when another orangutan came over to see what was going on. Bimbo – the only male in the group of five apes at Leipzig Zoo, in Germany - appears to be laughing in much the same way as a human would. (Photo by Martina Radtke/Solent News)

“Today, we take photography for granted. Anyone can take a photograph simply by pressing a button. Yet, it was not always so simple. The invention of photography was announced in 1839, but during its first fifty years taking a photograph was a complicated and expensive business. In 1888, all this was to change following the appearance of a camera that was to revolutionize photography. Popular photography can properly be said to have started 120 years ago with the introduction of the Kodak”. – The UK National Media Museum. Photo: Two men on the deck of a ship, about 1890.

Children beg for alms in a street on August 11, 2014 in Manila, Philippines. The Philippines has one of the fastest growing populations in Southeast Asia with around 100 million people. At least 12 million people live in the capital city of Manila alone, making it one of the most densely populated and largest cities in the world. Lack of space and economic opportunities has pushed around four million people to live informally along waterways, bridges and even cemeteries further straining the already weak infrastructure and straining the resources of the city.
