How do green roofs remove carbon dioxide from the atmosphere?
Green roofs remove carbon dioxide from the atmosphere because of photosynthesis. All plants perform photosynthesis and by doing this, they take out carbon from the atmosphere and produce oxygen. (They produce the oxygen we need to breathe). During photosynthesis, the plant's chlorophyll absorbs the sun's light and stores it as glucose. Then, they produce oxygen with the use of carbon. The reactants of photosynthesis are plants and carbon dioxide whereas the products are oxygen and cleaner air. Green roofs would reduce the high carbon dioxide levels by absorbing the carbon and producing oxygen.
Graphs showing yearly carbon emissions.
These two graphs show the carbon emissions from different types of fuels. Carbon emissions are too high and need to be lowered or there will be consequences. Both graphs are measured in million metric tons. The first graph shows up to the year 2000 while the second graph shows up to the year 2045. In 2045 on the second graph, two carbon producers increased whereas one decreased.
