Which of the following is a major contributor to global warming?

Step 1: Understand what global warming is. It is the increase in Earth's average temperature due to greenhouse gases.
Step 2: Learn about greenhouse gases. These are gases that trap heat in the atmosphere.
Step 3: Identify common greenhouse gases. Some examples are carbon dioxide, methane, and nitrous oxide.
Step 4: Focus on methane. Methane is a type of greenhouse gas that is much more effective at trapping heat than carbon dioxide.
Step 5: Recognize the sources of methane. It comes from sources like livestock, landfills, and natural gas production.
Step 6: Conclude that methane is a major contributor to global warming because it has a strong heat-trapping ability.
