Good morning, everyone. Today we're going to talk about urban planning, and I'd like to focus on the concept of 'green roofs'. As you might know, a green roof is a roof of a building that is partially or completely covered with vegetation. Now, some of you may think this is just an aesthetic choice, but in fact, it has several practical benefits. For instance, it can reduce the heat island effect in cities by absorbing sunlight. Additionally, it helps manage stormwater runoff, which can prevent flooding in urban areas. However, it's important to note that the initial installation cost is relatively high, and regular maintenance is required to keep the plants healthy. So, while the long-term environmental advantages are clear, the upfront investment can be a barrier for many building owners.
