In this article, George Adams discusses how cities are the engines powering the development of the human race: How does sustainable growth factor into this vision?
According to a World Bank study, an incredible 70% of the world’s cities outstrip their national gross domestic product.
By 2050, 600 cities will account for 60% of global domestic product and house 70% of the global population, which is forecast to be in the region of 10 billion.
However, this rapid development is not without cost. As it stands, cities currently house half of the world’s population, yet they produce almost three quarters of its waste. This might come as a surprise to city dwellers, given their access to public transport, modern buildings and comprehensive waste recycling services, but cities pollute our atmosphere disproportionately to the number of people who inhabit them.
