• A gasoline - powered car burns gasoline (a fossil fuel). Burning fossil fuels releases greenhouse gases.
• A coal - fired power plant burns coal (a fossil fuel), which releases greenhouse gases.
• When an animal breathes, it releases carbon dioxide (a greenhouse gas) as a by - product of respiration.
• A gas stove burns natural gas (a fossil fuel), and the combustion of natural gas releases greenhouse gases.

Answer:

a person driving a gasoline - powered car, a company operating a coal - fired power plant, an animal breathing, a chef cooking over a gas stove.
