B. How does a green roof reduces the amount of carbon dioxide in the atmosphere?

C.  Why is it important to reduce the amount of carbon dioxide in the atmosphere?

E. What are other ways the owners or architects of a building can reduce its carbon footprint?

Green Roofs
People in Albany and New York City are using "green roofs" to improve the
environment. A green roof can be added to many buildings that have large, flat roofs.
Green roofs have three parts: a protective layer to separate plant roots from the roof of the
building, an absorptive layer to catch and hold rainwater, and a layer of plants. Often,
green roofs use Sedum, a short, desert plant, because it is efficient at storing water in its
leaves and can withstand the colder climate.
A green roof saves energy, reduces carbon dioxide in the atmosphere, and prevents
rainwater and melting snow from overloading sewer systems. It can also protect the roof of
a building from damage. However, green roofs can be expensive to install, and require care
and maintenance.
