How do trees improve air quality?

Trees play a crucial role in improving air quality primarily by absorbing carbon dioxide (CO2) during the process of photosynthesis. This process not only reduces the concentration of CO2 in the atmosphere, which is a significant greenhouse gas contributing to climate change, but it also leads to the release of oxygen (O2) as a byproduct. The transformation of carbon dioxide into oxygen benefits not just the immediate environment but also contributes to the overall health of the planet's atmosphere.

In addition to carbon dioxide absorption, trees can also capture particulate matter, such as dust and smoke, through their leaves and bark, which helps to further purify the air. However, the fundamental mechanism through which trees directly improve air quality is their ability to absorb carbon dioxide and release oxygen, making this process essential for sustaining life and maintaining ecological balance.
