Vertical gardening is nothing more than using vertical space to grow vegetables (or herbs, or flowers , even root crops), often using containers that hang on a sunny wall. The Vertical Gardens help reduce the carbon foot print of the structure and cleans outside air of pollutants and dust. It also equalizes the carbon footprint of people and fuel emissions by filtering pollutant and carbon-dioxide out of the air. This benefits those living nearby and the quality of air is thus improved in built-up areas. It reduces urban heat island effect and smog.
