In today's lecture, we'll discuss the impact of urbanization on local ecosystems. One key point is that cities often create 'heat islands' due to concrete and asphalt absorbing sunlight. However, planting trees can reduce this effect by providing shade and releasing moisture. A recent study in Melbourne found that increasing tree cover by 20% could lower peak summer temperatures by up to 4 degrees Celsius. Additionally, green roofs are another solution, but they are more expensive to install. The study also noted that while trees help with cooling, they may increase water consumption in dry regions. Therefore, urban planners must balance these factors carefully.
