(I'll give brainliest) , Chemical energy sources are often portable and provide large amounts of energy. Fossil fuels are one ki
nd of chemical energy source. Most of the energy we use in the United States is generated by the combustion of fossil fuels. However, fossil fuel combustion adds greenhouse gases to the atmosphere, mostly CO2. One measure of the total amount of greenhouse gases that are emitted into the atmosphere each year is called a carbon footprint. Study these images to compare the carbon footprint of an average person in the United States to an average person around the world. Knowing that greenhouse gases are contributing to climate change, how can we reduce our carbon footprint, particularly in the United States? Could hydrogen fuel replace fossil fuels in the future? Why or why not? Should the size of a person’s carbon footprint be limited by law? Why or why not?
You can reduce our carbon footprints by using renewable energy,calculate your carbon footprint and make changes,use car less and minimize driving and walk or cycle more and reduce water use.
Hydrogen fuel can not replace fossil fuels this is because fossil fuel use more energy and make more pollution.
The answer is likely (E) Exposed... condemning. Although another possible answer could be (A) Portrayed... strengthening. But I would go for (E) myself.
