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, old, 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.
