2022 Teens Dream - Cleaning the world

My dream is to make the action of cleaning the world more common with the help of an app where you could post your efforts to improve the world we live in. This relates to the 12 SDG, Responsible Consumption and Production, but it can also relate to the 14 and 15 SDG, Life Below Water and Life On Land, but this depends on which actions choose the users of the app.
