I think sometimes people forget, or just frankly don't know, the thousands of products that we own, use, interact with, and see everyday that are made from fossil fuels such as petroleum. The gas in our cars and tractors and planes and power plants and other big visible machines are the things most associated with fossil fuels to most people but just simply go to a grocery store and down every aisle are hundreds upon hundreds, thousands really, of products that are made from fossil fuels. As dirty as they are we can't just simply pretend that our country can just stop using fossil fuels overnight or even over one presidential term. It will take a lot of time, effort, money, alternatives, will power, thought, sacrifices, and calm in order to convert completely away from fossil fuels. It's worth the effort, but we really also need to be realistic about the process in my opinion.
