In today's lecture, we'll discuss the impact of urban green spaces. Recent studies show that access to parks not only improves mental health but also reduces urban heat. For example, a city in Australia planted over 5,000 trees along main roads, which lowered local temperatures by up to 3 degrees Celsius. However, the most significant benefit was observed in residential areas with community gardens, where residents reported a 20% decrease in stress levels. Interestingly, the size of the green space mattered less than its proximity to homes.
