The Blue Marble is an image of planet Earth taken on December 7, 1972, by the crew of the Apollo 17 spacecraft at a distance of about 29,000 kilometres (18,000 miles) from the surface. It is one of the most reproduced images in human history. This photograph was also used by ecologists as an illustration of our weakness, sensitivity and loneliness in space. This TEDx Katowice event will hold discussions on how we are adapting our lifestyles to the problems the Earth faces, looking at what has worked, what has not, and what have we yet to do. Various speakers will be on hand, some speaking in Polish as well as some in English. The event will take place at ING Bank Śląski on Sokolska 34. Live streaming available in this link.
