Question

List any three human activities which would lead to an increase in the carbon dioxide content of the air.

Answer 1

Greenhouse gases:

• A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.
• Almost the majority of the rise in greenhouse gases in the atmosphere is due to human activity.
• In the United States, the main source of greenhouse gas emissions from human activity is the use of fossil fuels for power, heat, and transportation.
• Human sources of carbon dioxide emissions have increased since the Industrial Revolution.
• These three actions encourage the emission of carbon dioxide into the atmosphere.
  • The combustion of fossil fuels such as gasoline and diesel is used for transportation and industrial reasons.
  • Heating and cooking using wood and charcoal.
  • Deforestation/tree cutting
