What is the role of plants in improving the environment?

Plants resistant to pollution (white acacia, yellow acacia, poplar, chestnut, birch, alder, willow, hawthorn, lilac, larch) are used for landscaping cities with developed industry and an abundance of cars. These plants actively absorb various harmful substances from the air and are good dust collectors. Plants skillfully used in landscaping not only cleanse the air of harmful substances, but also make settlements cozy and beautiful. Plants sensitive to pollution can serve as indicators of the state of the environment.
