Discover London, New York et Tokyo

With more than 15,000 species of wild animals, the city of London, was awarded the title of "the world's first urban national park". It also has 8,400,000 trees in 8,000 parks and 3.8 million private gardens, or nearly one tree per inhabitant.

By 2050, the GrowNYC project plans to make new york "the most sustainable city in the world". This program provides for 1 million additional trees by 2030 and a 35% reduction in greenhouse gas emissions by 2025.

To counter the decline in its biodiversity, Tokyo has been pursuing an environmental conservation policy since 2012, for example by developing ecological corridors between parks allowing different species to extend their habitat.
