Four Ways Forests Affect the Atmosphere — Reading Comprehension

Forests play a vital role in regulating the Earth’s atmosphere. Here are four key ways they influence atmospheric conditions:

1. Carbon Sequestration: Forests absorb carbon dioxide (CO₂) from the atmosphere during photosynthesis and store it in trees, plants, and soil. This process helps reduce greenhouse gases, which are responsible for global warming.

    

2. Oxygen Production: Trees release oxygen as a byproduct of photosynthesis. A single mature tree can produce enough oxygen for two to ten people annually, making forests essential for clean air.

    

3. Temperature Regulation: Forests help cool the planet by providing shade and releasing water vapor through transpiration. This process creates a cooling effect, which can lower local temperatures and combat urban heat islands.

    

4. Air Quality Improvement: Trees filter pollutants like nitrogen oxides and sulfur dioxide from the air. They also trap dust and particulate matter, improving air quality and reducing respiratory illnesses.

However, deforestation disrupts these benefits. Cutting down forests releases stored CO₂, reduces oxygen production, and worsens air quality. Protecting and restoring forests is crucial for maintaining a healthy atmosphere.

Fun fact: The Amazon rainforest produces 20% of the world’s oxygen, earning it the nickname “the lungs of the Earth.”
