How can air pollution be combated through the use of liquid trees?

In Bangladesh, the deteriorating air quality, especially in urban centers like Dhaka, highlights the urgent need to understand and harness the role of trees in mitigating air pollution. According to data from the World Air Quality Index project, the levels of pollution in several Bangladeshi cities rank among the highest globally, posing serious health risks to the population. Trees are nature’s air purifiers, absorbing harmful pollutants such as carbon monoxide, sulfur dioxide, and nitrogen dioxide, thus playing a crucial role in enhancing air quality. However, the challenge lies in the rapid pace of urbanization and deforestation, which have drastically reduced green spaces, undermining this natural defense against pollution. As urban areas expand, the loss of trees compromises their ability to act as a buffer against air pollution. This reduction in green cover not only affects air quality but also impacts urban heat islands and biodiversity. Addressing this issue requires innovative and practical solutions beyond traditional tree planting, such as a form of liquid tree could be an alternative. Moreover, alternatives could include developing vertical gardens, green walls, and rooftop gardens, or implementing policies for urban green space preservation and expansion. Additionally, exploring and investing in advanced air purification technologies can serve as an immediate alternative to the natural air filtration provided by trees.
