The most populous city in the world

The more developed cities pay attention to the environment.

To get a clearer picture of the world's "coolest" cities , Massachusetts Institute of Technology Senseable (MIT), the United States cooperates with the World Economic Forum (WEF) to create Treepedia , page. The web has an interactive map showing the density of crops in major global cities.

The team used information from Google Street View (Google Street View) to determine the "Green Index" , the rate of each city 's tree planting land based on aerial imagery. When launched in 2016, Treepedia has only 10 cities, but has gradually added.
