Today, in our environmental science lecture, we're discussing the impact of urban development on local ecosystems. One key point is the role of green roofs. Unlike traditional roofs, which absorb heat and contribute to the 'urban heat island' effect, green roofs are covered with vegetation. They not only reduce building energy costs by providing insulation but also manage stormwater runoff. However, their installation cost is higher, and maintenance requires regular watering, especially in dry climates. Despite these challenges, many cities now offer tax incentives to encourage their adoption. So, while the initial investment may be significant, the long-term environmental and economic benefits are considerable.
