Final answer:
Increasing the use of fossil fuels is likely to increase global warming and have impacts on ecosystems.
Step-by-step explanation:
Increasing the use of fossil fuels is likely to have the effect of increasing global warming. Fossil fuels, such as coal, oil, and natural gas, release carbon dioxide and other greenhouse gases when burned. These gases trap heat in the atmosphere, leading to a rise in global temperatures. This rise in temperature can disrupt ecosystems, affecting biodiversity and causing changes in precipitation patterns, sea levels, and weather events.
