Summary of the argument by Prof. Mark Swilling
It is generally accepted that the defining social character of our age is that the majority of people on the planet now live in cities. The 2.5 billion people that will take the global population from the current 7 billion to the projected 9.5 billion by 2050 will end up living in African and Asian cities. The end result will be the urbanization of nearly 4 billion people between 1950 and 2030, mainly in the cities of the global South. At the same time, it is also generally accepted that we also face an unprecedented global ecological crisis due to global warming, resource depletion and the gradual destruction of life-supporting ecosystem services. Indeed, we face this ecological crisis from the vantage point of the urban age. But both are unprecedented: never before has the majority of humanity lived in cities, and never before has humanity been a geo-physical force of nature. We are, in short, in an urbanized anthropocene.
