How does rooftop gardens or patio gardens improve air quality?

Rooftop and patio gardens improve air quality by absorbing carbon dioxide and releasing oxygen through photosynthesis. They also filter pollutants and particulate matter from the air, acting as natural air purifiers. Additionally, these green spaces can help reduce urban heat islands, lowering temperatures and improving overall air quality in densely populated areas. By providing habitats for pollinators and other wildlife, they contribute to biodiversity, further enhancing ecological health.
