Both the developed and developing worlds have been undergoing massive amounts of urbanization over the last century, and that trend is expected to continue for the next several decades. It’s believed that 86% of the developed world and 64% of the developing world will be urbanized by 2050, and while there are plenty of benefits to living in dense urban areas, having so many people living so close together creates a number of problems, ranging from massive amounts of pollution to the over-consumption of resources. Fortunately, there are plenty of startups that want to help solve these problems, and a venture fund by the name of Urban.us has raised an additional $10 million to invest into these startups.
