Trees for Healthy Cities: Solving Air Pollution with Urban Forests

From the great China metropolis to the most populated European capitals, cities around the world have been fighting air pollution for decades. Can urban forests be the answer to theproblem?

Experts have been studying the physiological responses of plants to climate change. They claim thatplantingthe right species of treesin the most appropriate climate, soil, or region could help with air pollution. Using a continuous emission monitoring system to detect locations of severe contamination, engineers can build urban forest areas that will help remove impurities in major cities.

Urban Forests and Their Role in Solving Air Pollution

Urban forests include parks, street trees, boulevards, gardens and all kinds of green spaces situated in a highly industrial city or neighborhood. More than just ecosystems that help shelter wildlife and give a home to plants, they have a huge role in the ecology of human habitats.

Urban forests affect air quality by altering the atmospheric environments of cities. Trees and vegetation greatly help inreducingthe temperature by converting liquid water taken from the soil to water vapor in the atmosphere.

Trees also purify air through a process called carbon sequestration. This process involves the intake and storage of the element carbon and gaseous air pollutants such as ozone, sulfur dioxide, nitrogen oxide, and ammonia through the stomata found in the leaves’ surface. This helps remove carbon that would otherwise rise and trap heat in our atmosphere, which causes global warming.

To build sustainable cities of the future, we have to start living with trees. Building an urban forestnot only enhances our landscape but also helps clean our air with natural continuous emissions monitoring.

Tree planting alone will not solve the world’s pollution problem. However, employing a strategic tree planting method and creating urban forestsmay save thousands of lives. Lushonesfilled with trees appropriate for the area would help reducesmog in highly dense and populated cities.

Despite technological advancements and breakthroughs, attaining clean air in cities remains a challenge. Scientists are continually researching new technologies that will combat air impurities, including the switch from diesel to alternative fuel, liquid air, and air purification through the help of a continuous emission monitoring system. Building urban forests is just the first step in eliminating air pollution once and for all.
