“Cities have always been centers of innovation, and today, urban leaders are inspiring one another to new heights of sustainability”
are in the midst of one of the greatest human migrations that our world has ever seen — that of humanity from rural areas into cities. In China alone, 400 million people have already made this transition. Towns that were once fishing villages grew to megacities with 10 million or more inhabitants in just 30 years. This trend is happening on every continent.
Cities need nature, and nature needs cities. Nature can protect cities from natural disaster, by providing new solutions for managing water, cleaning the air and cooling our streets. Nature can make the lives of city residents better, improving their health and wellbeing.
