| 2. How does air pollution affect human health? | |
Ans. Air pollution can have detrimental effects on human health. Breathing in polluted air can lead to respiratory problems such as asthma, bronchitis, and other respiratory infections.

Ans. Deforestation poses several health risks to both local communities and global populations. One major risk is the loss of biodiversity, which can disrupt ecosystems and increase the transmission of zoonotic diseases from animals to humans. Deforestation also contributes to climate change, which has numerous health impacts as mentioned earlier. Furthermore, deforestation reduces access to clean air and water, leading to respiratory problems and waterborne illnesses.
