Question

since 1965, global use of fossil fuels and global co, emissions have increased steadily. using more renewable energy in place of fossil fuels is one way to reduce co, emissions. another way to reduce co, emissions is to use less energy overall. for example, biking, walking, or taking public transportation instead of riding in a car saves energy. modern technologies, such as led light bulbs, can also help save energy. led light bulbs use 75% less energy than incandescent light bulbs to provide the same amount of light. click the blue words to correct the statements. over the past 50 years, both fossil fuel use and co, emissions have increased. because co, emissions are a main cause of climate change, people around the world are working to reduce emissions. by relying more on fossil fuels and using less energy overall, people can help reduce co, emissions and other negative environmental impacts of renewable energy.

Explanation:

The first statement is correct as the text says since 1965 (which is more than 50 years) global use of fossil fuels and CO₂ emissions have increased. For the second statement, the error is in "relying more on fossil fuels" (should be renewable energy as per the text) and "negative environmental impacts of renewable energy" (renewable energy is presented as a way to reduce emissions, so it's incorrect; the negative impacts are of fossil fuels).

Answer:

Over the past 50 years, both fossil fuel use and CO₂ emissions have increased. (Correct). Because CO₂ emissions are a main cause of climate change, people around the world are working to reduce emissions. By relying more on renewable energy and using less energy overall, people can help reduce CO₂ emissions and other negative environmental impacts of fossil fuels.
