The global population is expected to reach up to 10 billion by 2050. Seven out of these ten billion people are expected to live in cities - so we are consequently developing ourselves into an urbanized species. This situation will create demands on the city - and on people; calling for respect and cooperation, responsibility and the development of new technologies, for mental transformations, new values, empowerment and enlightenment. And without sustainability, it cannot be done. Living sustainably is one of the biggest challenges today. Another challenge - even bigger in the past – is how to stay healthy.
