Match the activities (1 - 3) with their possible effects on the environment (a - f).
1. Cutting down or burning forests | a. When burnt, fossil fuels release greenhouse gases, trapping heat in the atmosphere. |
b. When eating, these animals produce a lot of methane. This gas is responsible for nearly one-third of current global warming. | |
2. Burning coal, oil, and gas | c. Trees use CO2 to grow, so when they are cut down or burnt, the CO2 in the air increase. |
d. Carbon from fossil fuels combines with oxygen in the air to form large amounts of CO2. | |
3. Raising farm animals like goats, sheep, and cows | e. Forests store carbon in the trees and soil, and help reduce the global temperature. |
f. Forests are cut down to make space for farm animals. |
