Today I took these picture from my office window – The red dots are window cleaners, people, hanging on the outside of a skyscraper. This is 40-50 floors in the air on the exterior of the building. In China I remain shocked by the social challenges I see, one of the most concerning is workers safety, this remains an area where I see things weekly that continue to surprises me. Sparkling, mirror clad skyscrapers rising up in all the major cities around China a symbol of advancement and economic growth . By the end of next year one-in-three of the world’s 100m+ skyscrapers will be in China, as its state-orchestrated urbanisation drive prompts a megacity building bonanza.
