Question

A. Most varieties of Sedum are not native plants in Albany or New York City. Why may it be dangerous to introduce a new species to an established ecosystem?

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?

D. State one disadvantage of a green roof.

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. ### Diagram Explanation The included diagram illustrates the structure of a "green roof." It displays the following layers in order from top to bottom: 1. **Plants:** This is the topmost layer consisting of vegetation, often *Sedum*. 2. **Absorptive Layer:** Situated beneath the plants, this layer catches and retains rainwater. 3. **Protective Layer:** The bottom layer separates the plant roots from the roof of the building, ensuring that the roots do not interfere with the integrity of the roof. Each layer serves a crucial function in maintaining the efficiency and effectiveness of the green roof, highlighting their roles in environmental sustainability and building protection.
