International Day of Forests 2018: Forests and sustainable cities

More people live in cities than ever before and by 2050, 6 billion people or as much as 70% of the global population is expected to live in urban areas. But rapid urbanization does not need to result in polluted urban sprawl. Trees and urban forests can make our cities greener, healthier and happier places to live by cooling the air, filtering out harmful pollutants and mitigating the effects of climate change.
