Question
How are humans contributing to greenhouse gas effect?
- By burning wood.
- By preferring car-pooling.
- By using eco-friendly materials.
- All of the above
Hint:
Human Activity Is the Cause of Increased Greenhouse Gas Concentrations.
The correct answer is: By burning wood.
Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
