Dr. Thompson--Oil

The only thing that really ever came to mind when the subject oil came up was that it kills many animals and plants each year by oil spills. Obviously I have not been well informed. I never realized how much of our everyday use is possible by a series of chemicals which creates oil. The most unusual fact that surprised me was that humans and a lot of creatures contain oil. It might just be me but that’s weird. The whole process of extracting and transporting oil is extremely interesting and is amazing what natural resources that our ecosystems provide for us. Maybe I missed this point but if we out way coal and oil disaster which one is of greater harm and occurs more? If anyone can answer this question please write me back.
