From reading this article I learned a lot about the non-renewable resources out there and how most are fossil fuels. It was really interesting to find out when they got started and there time period, the Carboniferous Period. This period was about 360-300 million years ago, and formed before the Dinosaurs. This article mentioned how the Earth was a different landscape at that time, and it was covered with wide shallow seas, with swampy forests. The only thing that grew were plants, algae, and plankton. How this period got started was these plants, algae, and plankton, absorbed the sunlight's energy through photosynthesis, then when they died, the organisms drifted to the bottom of the sea floor. Over time then, the dead plants were crushed under rocks and sediment creating a heated pressure underground. With this pressure and heat it turned the dead plants into fossil fuels such as; coal, natural gas, and petroleum. Now there are lots of pockets underground of fossil fuels all over the world. Fossil fuels are valuable and abundant, unfortunately they are also harmful as according to this article, when they are burned they pollute our air quality or supply.
