The vegetation plays an important positive role in atmospheric purification and air pollutants reduction.
Compared to other land uses, coniferous forests were particularly effective in removing air pollution because of their high tree cover density and the duration of leaf life-span.
It seems that the potential of roadside vegetation to mitigate air pollution is largely determined by the vegetation effects on airflow.
However, air particulate pollution, which is likely to be dominated by large-sized particles in our study, can be reduced by urban vegetation.

How has the increase in pollution contributed to global warming and climate change?5 answersThe increase in pollution has contributed to global warming and climate change. Pollutants released into the air, water, and soil, as well as high decibel noise and plastics, have a significant impact on human health and well-being. Air pollution, including greenhouse gases and other air contaminants, is a major contributor to climate change. The release of toxic chemicals into the water, dangerous gases into the air, and human activities like mining and ore purification all contribute to global warming and shifting weather patterns. Pesticides, which contaminate both soil and water, also contribute to climate change and impact the overall growth and yield of plants. The pollution of the environment, particularly in urban areas, has led to the emission of greenhouse gases and the depletion of the ozone layer, resulting in climate change and its harmful effects on ecosystems and human health. Overall, pollution plays a significant role in driving global warming and climate change.
What are the effects of deforestation and pollution on biodiversity?5 answersDeforestation and pollution have severe effects on biodiversity. Deforestation, particularly in tropical regions, leads to the destruction of habitats and a decrease in the quality of soil and water, ultimately impacting biodiversity. Pollution, including air pollution caused by human activities, contributes to the degradation of the atmosphere and poses a threat to the survival of various species. The pollutants released into the air, such as NO2, SO2, CO, CFCs, and Ozone, have detrimental effects on the environment and can harm biodiversity. The destruction of forests and the pollution of the atmosphere disrupt the ecological balance and pose significant risks to the biosphere and the life-support system. These impacts on biodiversity have far-reaching consequences for both nature and humanity, highlighting the urgent need for measures to reduce deforestation and pollution.
How trees in urban areas help in reducing air pollution?5 answersTrees in urban areas help in reducing air pollution by acting as natural air purifiers. They have the ability to remove gaseous and particulate pollutants from the air, thereby improving air quality. Trees can attenuate the concentration of inhalable, thoracic, and alveolic particles, reducing public exposure to traffic-related air pollutants. Urban green spaces, created by municipalities, including trees and shrubs, can significantly improve air quality by reducing artificially produced pollutants. Trees also contribute to the removal of air pollutants such as carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide, through processes like carbon storage and sequestration. Additionally, trees help in regulating atmospheric temperature and mitigating floods, further contributing to a healthier urban environment. Overall, the presence of trees in urban areas plays a crucial role in reducing air pollution and its associated health risks.
How has tree canopy cover decreased over time?5 answersTree canopy cover has decreased over time in various regions. The West and Northeast regions of the contiguous United States experienced significant tree canopy loss between 2010 and 2020, while the Midwest/Great Lakes region saw an increase in tree canopy coverage. In two Melbourne suburbs, there was evidence of a net decrease in urban tree canopy cover due to urban infill development, although other suburbs showed no significant change. In a study of pinyon-juniper woodlands, canopy cover increased from 1936 to 2002 but was then reduced by 55% during a major drought in 2002-2004. These findings highlight the need for policy considerations and changes in tree protection and infill development planning to address the decrease in tree canopy cover and ensure the sustainability of urban forests.
