Which human activity is correctly paired with the greenhouse gas that it increases?

Step 1: Define the Problem

Identify the human activities and their corresponding greenhouse gases.

Step 2: Break Down the Problem

1. List common human activities that contribute to greenhouse gas emissions.
2. Identify the specific greenhouse gases associated with each activity.

Step 3: Apply Relevant Concepts

• Burning fossil fuels: Increases carbon dioxide (CO₂).
• Agriculture (especially rice paddies and livestock): Increases methane (CH₄).
• Use of industrial refrigerants: Increases chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs).
• Deforestation: Reduces CO₂ absorption, indirectly increasing atmospheric CO₂.

Step 4: Analysis, Verify and Summarize

• Burning fossil fuels is a major source of CO₂, a primary greenhouse gas.
• Agriculture is a significant source of CH₄ due to enteric fermentation in livestock and anaerobic decomposition in rice paddies.
• Industrial activities involving refrigerants contribute to CFCs and HFCs, potent greenhouse gases.
• Deforestation decreases the number of trees available to absorb CO₂, leading to higher atmospheric levels.

Final Answer

Burning fossil fuels is correctly paired with the increase in carbon dioxide (CO₂).
