Explanation:
- The balance of gases in the air refers to the natural composition of gases that make up the Earth's atmosphere. This composition includes oxygen, nitrogen, carbon dioxide, and other trace gases.
- Disturbing the balance of gases in the air can have negative effects on the environment and human health.
- Cutting down trees and forests: Trees play a crucial role in maintaining the balance of gases in the air. They absorb carbon dioxide through photosynthesis and release oxygen. Therefore, cutting down trees and forests disrupts this balance by reducing the amount of oxygen produced and increasing the amount of carbon dioxide in the atmosphere. This contributes to the greenhouse effect and climate change.
- Releasing polluting gases into the air: The release of polluting gases, such as carbon dioxide, methane, and nitrogen oxides, into the air can disturb the balance of gases. These gases are often emitted by human activities such as burning fossil fuels, industrial processes, and agriculture. They contribute to air pollution and can lead to the formation of smog and harmful particles in the atmosphere.
- Growing trees: Growing trees can actually help restore the balance of gases in the air. As mentioned earlier, trees absorb carbon dioxide and release oxygen through photosynthesis. Planting and growing trees can help mitigate the effects of greenhouse gases and improve air quality.
- Releasing smoke from vehicles: The smoke released from vehicles, particularly those that burn fossil fuels, can contribute to air pollution and disturb the balance of gases in the air. This smoke often contains harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. These pollutants can have detrimental effects on human health and the environment.
- Based on the above explanations, the option that does not disturb the balance of gases in the air is growing trees. Growing trees helps restore the balance by absorbing carbon dioxide and releasing oxygen through photosynthesis.
