Read the following passage:
An increase in automobile use has led to increased
demand for fuel. The extraction, processing , and delivery
of fuel put harmful pollutants into the atmosphere. The
fuel that is then consumed by engines creates carbon
dioxide emissions. The carbon dioxide creates a
greenhouse effect in the atmosphere. The gasses trap
heat in Earth's atmosphere, leading to global warming.
