A city that is located in a warm climate is concerned about the amount of carbon in the atmosphere. The city commission plans to address this concern by choosing a design that adds plants around their city hall building. The three designs proposed for the city hall building are a green wall, a green roof, and a lawn garden. A green wall is a vertical garden that grows on the side of city hall building. A green roof is a layer of vegetation over a waterproof system that is installed on the roof of the city hall building. A lawn garden is the addition of new plants around the city hall building to replace the grass. Each design also cools the surrounding area, leading to a decrease in temperature of the city hall building. The table shows the details recorded about the project.

Question

How will the new design affect the environment?

A.
The plants in the design will add carbon to the atmosphere. Adding carbon to the atmosphere helps to increase the severity of climate change.

B.
The plants in the design will add carbon to the atmosphere. Adding carbon to the atmosphere helps to decrease the severity of climate change.

C.
The plants in the design will remove carbon from the atmosphere. Removing carbon from the atmosphere helps to increase the severity of climate change.

D.
The plants in the design will remove carbon from the atmosphere. Removing carbon from the atmosphere helps to decrease the severity of climate change.

Answer 1

The correct answer is:

D. The plants in the design will remove carbon from the atmosphere. Removing carbon from the atmosphere helps to decrease the severity of climate change.

Plants absorb carbon dioxide (CO2) during photosynthesis, leading to a reduction in atmospheric carbon levels. This process helps mitigate climate change by lowering greenhouse gas concentrations.
