1. Reduce Gaseous pollution : In cities and towns, there is a rise in gaseous pollution like(CO2, CO, SO2 etc). So city environments are highly polluted and unsafe for living. This is due to automobiles and factories ejecting toxic gases and also reducing the healthy oxygen ratio of air. Air pollution causes diseases of various types. So growing plants on the roadside, parks etc. helps minimize the gaseous pollution. For the benefit of plants oxygen they can even be grow in office, residential areas, education institutes etc. For this we can use low maintenance plants like indoor potted plants, hanging plants etc.
