We continue our conversation around fossil fuels and why critics advocate lessening our dependence on them. 

We look at fossil fuels' effect on our environment and how greenhouse gasses work. We also look into the risk where experts expect we will eventually run out of fossil fuels and need to find replacement energy sources before we run out of fuel. Additionally fossil fuels are not found everywhere, and as a result, dependence on fossil fuels can lead to countries depending on foreign trade partners for their energy, which can lead to political complications.
