Question

In many crowded cities, open green space is hard to find. As a result,
some communities have started transforming unused rooftops into
gardens. These rooftop gardens provide several important benefits
for both people and the environment.
To start, rooftop gardens help reduce extreme heat in urban areas.
Large amounts of concrete and asphalt absorb sunlight, raising city
temperatures. Plants, on the other hand, cool the air by releasing
moisture. Because of this natural process, buildings with rooftop
gardens often require less air‑conditioning, which saves energy.
Rooftop gardens also help manage rainwater. During heavy storms,
city drainage systems can become overwhelmed. Soil and plants on
rooftops absorb much of the rain, reducing flooding and preventing
polluted water from rushing into rivers and streams.
Finally, these gardens create new habitats for birds, butterflies, and
insects. In cities where wildlife is limited, even small patches of
greenery can support local ecosystems. Some rooftop gardens even
grow vegetables, giving residents access to fresh produce.
As cities continue to grow, rooftop gardens offer a practical and
creative way to make urban areas healthier and more sustainablewrite 3–4

Answer 1

Rooftop gardens transform unused roof space into green areas that cool cities, lower building air‑conditioning needs, and save energy. They absorb rainwater to reduce flooding and prevent polluted runoff, easing pressure on urban drainage systems. Additionally, rooftop gardens create habitats for wildlife and can provide fresh produce, improving urban sustainability and residents’ well‑being.
