(Nối các hoạt động (1 - 3) với các tác động có thể có của chúng đối với môi trường (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. |
