deforestation affects animals, humans and the economy. Create a visual or typed presentation that summarizes your
findings.
2. Research and explain the process by which the oceans absorb and store carbon dioxide. How do humans, plants
and animals play a role in this process? Create a visual or typed presentation that summarizes your findings.
3. Create a visual or typed presentation about the effects of burning fossil fuels on the carbon cycle. Include ways that
people can work to maintain the balance of stored and released carbon compounds on Earth.
Requirements:
Typed presentation: Arial, 12 font, single spaced, two-full pages minimum - five pages maximum
You must include references with all work.
