Today, in our environmental science lecture, we'll discuss the impact of urban green spaces. Recent studies show that parks and community gardens can reduce city temperatures by up to 2 degrees Celsius. However, the key factor isn't the size of the green area, but its connectivity. A series of small, linked green spaces is more effective than one large isolated park. This is because connected corridors allow better air flow and provide habitats for wildlife. Also, these green networks encourage residents to walk or cycle, reducing car use. So, when planning sustainable cities, we should prioritize creating a web of green spaces rather than focusing solely on large parks.
