Our mission is to keep the parks and green areas in London clean. They are the lungs of the city, which are the main source of fresh air. Caring for parks and maintaining them helps reduce harmful emissions into the air because the trees and plants in them purify the air in a natural and safe way for people. To take care of the parks, we encouraged people to plant plants and trees in the them with free medal and certificates for this initiative. The certificates will be for appreciation for caring for the "London's Lungs". They will also receive a sign on which to write their name or whatever they want and put it next to the tree or plant they planted.
