click the blue words to correct the statements.
over the past 50 years, both fossil fuel use and co₂ emissions have increased. because co₂ 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 co₂ emissions and other negative environmental impacts of renewable energy.

Explanation:

To correct the statements:

1. "increased" is correct as fossil fuel use and CO₂ emissions have increased over 50 years.
2. "more on fossil fuels" should be "more on renewable energy" since relying on fossil fuels increases emissions.
3. "renewable energy" in the last part is incorrect; it should be "fossil fuels" as fossil fuels have negative environmental impacts, while renewable energy is better. So the blue words to correct are "more", "fossil fuels", and "renewable energy" (replace "more on fossil fuels" with "more on renewable energy" and "renewable energy" with "fossil fuels").

Answer:

• For "more on fossil fuels": Replace with "more on renewable energy"
• For "renewable energy" (last part): Replace with "fossil fuels"
