"Since the 1997 handover of Hong Kong to China, the semi-autonomous city has operated under a "one country, two systems" formula, allowing a limited democracy. In August, the Chinese government announced plans to vet candidates in Hong Kong’s 2017 elections, virtually assuring only pro-Beijing politicians would be on the ballots. Student groups and pro-democracy supporters have taken to the streets in recent days to protest the limitations and to demand universal suffrage. Tens of thousands of demonstrators have occupied Hong Kong’s Central District, bringing parts of the city to a standstill. The protests are one of the largest political challenges to Beijing since the 1989 Tiananmen Square crackdown. Chinese officials have scolded protesters and warned against any foreign interference."

Captive Landscapes - Daniel Kukla

Daniel Kukla, the Brooklyn-based photographer, photographed the interiors of animal enclosure at 15 different zoos across the US and Europe. He says in his Artist Statement: “We, as humans, go to great lengths to satisfy our desire for a connection with the natural world, especially in our interactions with wild and exotic animals. Zoos are the primary site for this relationship, but they often obscure the conflicts inherent in maintaining and displaying captive wild animals.” Inviting the viewer to question the role of constructed habitats, these images explore the motivations behind controlling the natural world.

Subotzky’s book on Pointe City is finally being released tomorrow! I deeply respect and admire their careful, compassionate and deeply conscious relationship to the communities they work with, and their approach to photography as a whole. Hear Subotzky speak through poetry and empathy on his work at a TEDx talk here.

Mikhael Subotzky & Patrick Waterhouse: Pointe City, Johannesberg South Africa.

Mikhael Subotzky and Patrick Waterhouse spent much of the years 2008, 2009 and 2010 engaged in the quixotic task of taking a photograph out of every window, of every internal door, and of every television-set in Ponte City. This circular 54-story building has been the subject of their three-year investigation of its structure and its position as the crucible of Johannesburg´s urban mythology.

Pointe City Background (from Artist’s Website):

The fifty-four-storey Ponte City building dominates Johannesburg’s skyline, its huge blinking advertising crown visible from Soweto in the south to Sandton in the north. When it was built in 1976 – the year of the Soweto uprisings – the surrounding flatlands of Berea, Hillbrow and Yeoville were exclusively white, and home to young middle-class couples, students and Jewish grandmothers. Ponte City was separated by apartheid urban planning from the unforgettable events of that year. But as the city changed in anticipation and response to the arrival of democracy in 1994, many residents joined the exodus towards the supposed safety of the northern suburbs, the vacated areas becoming associated with crime, urban decay and, most of all, the influx of foreign nationals from neighbouring African countries.

Ponte’s iconic structure soon became a symbol of the downturn in central Johannesburg. The reality of the building and its many fictions have always integrated seamlessly into a patchwork of myths and projections that reveals as much about the psyche of the city as it does about the building itself. Tales of brazen crack and prostitution rings operating from its car parks, four storeys of trash accumulating in its open core, snakes, ghosts and frequent suicides have all added to the building’s legend. Some of these stories are actually true, and for quite some time most of the residents were indeed illegal immigrants. And yet, one is left with the feeling that even the building’s notoriety is somewhat exaggerated – that its decline is just as fictional as its initial utopian intentions were misplaced and unrealized.

Mountains of used tires lay on a dump in the countryside on September 24, 2014 in Sesena Nuevo, near Madrid, Spain. Used tyres dump site in Sesena is a major environmental problem and was declared ilegal back in 2003, It currently stores over 75.000 tonnes of tires. The company, which ran it, received many penalties had to leave. Finally the regional goverments have now started to process the tires in order to clear the area within aproximately four years. Most of the material will be recycled for building materials, surfacing for roads, sports tracks and children’s playgrounds. (Photo by Pablo Blazquez Dominguez/Getty Images)
