Today, in our environmental science lecture, we'll discuss the impact of urban green spaces on air quality. Recent studies show that parks and community gardens can reduce local temperatures by up to 3 degrees Celsius. More importantly, trees absorb pollutants like nitrogen dioxide and particulate matter, which are linked to respiratory diseases. However, the effectiveness depends on tree species and layout. For instance, dense clusters of broadleaf trees are more efficient than scattered conifers. A city in the UK reported a 15% drop in asthma cases after expanding its green corridors. So, for future urban planning, integrating green spaces is not just aesthetic but a public health priority.
