An airplane flight from Minneapolis to Alaska takes 4.75 hours. On average, 200 pounds of Carbon Dioxide are given off per person, per hour by the airplane. If the flight has 220 passengers, how many Red Oak trees would need to be planted in order to absorb the amount of Carbon Dioxide given off for the entire flight?

220 passengers x 4.75 hours x 200 pounds of Carbon Dioxide per person per hour = 21,000 pounds of Carbon Dioxide given off for the entire flight.

Red Oak trees absorb approximately 48 pounds of Carbon Dioxide per year. Therefore, 21,000 pounds of Carbon Dioxide would require 437.5 Red Oak trees to be planted in order to absorb the amount of Carbon Dioxide given off for the entire flight.
