“Mix of science, politics can result in bad policy” (Our Views, Nov. 28) took the position that reducing fossil fuel use would be too costly and hurt the economy. One result of fossil fuel use that wasn't mentioned is the pollution that hurts our health. “Autism, pollution link is suggested by study” (Associated Press, Nov. 28) cited a scientific paper that linked automobile exhaust with autism, a major neurological disorder of our children. Such a scientific link with fossil fuel combustion and automobile exhaust was made previously for cardiovascular disease and cancer. In addition, fossil fuel combustion is releasing the neurotoxin mercury into the environment, which is contaminating fish as well as the people who eat fish.
