What is the role of carbon dioxide in global warming?

Back

Carbon dioxide is a significant greenhouse gas that traps heat in the atmosphere, contributing to global warming and climate change.

Front

What health problems can air pollution cause?

Back

Air pollution can lead to respiratory issues, heart problems, and increased risk of diseases such as asthma and lung cancer.

Front

Are all greenhouse gases man-made?

Back

No, some greenhouse gases are naturally occurring, such as water vapor and carbon dioxide, while others are primarily produced by human activities.

Front

What is smog?

Back

Smog is a type of air pollution that combines smoke and fog, often resulting from industrial emissions and vehicle exhaust.
