How might we utilize green roofs and living walls in urban areas to contribute to biodiversity and reduce the urban heat island effect?

ANSWER: Green roofs and living walls in urban areas can enhance biodiversity by providing habitats for various plants, insects, and birds. These vegetated spaces mimic natural ecosystems, supporting pollinators and increasing local flora and fauna diversity. By replacing traditional building surfaces with plant life, they also mitigate the urban heat island effect by absorbing sunlight and heat, cooling the air through evapotranspiration, and improving air quality. Incorporating them into urban planning can create greener, healthier, and more sustainable cities.
