Problem: Many people identify trees as an important and useful carbon sink in our environment. Use your calculating skills to estimate how effective it would be if everyone in the world planted a tree tomorrow.
a) Assume that each tree (regardless of its size) produces 9 kg 02 per year through photosynthesis. Determine how long it would take these trees take to make a 1-ppm difference in the CO2 concentration in the atmosphere?
b. Discuss the results of your calculation to assess this as a practical climate solution. Consider the assumptions you made in your calculations, as well as any other radiative forcing effects that could occur as a result of planting this many trees.
