This website shows the process of fracking.

This article connects our last unit to our present one, showing another harmful effect of fossil fuels as an energy source. Hydraulic fracturing or "Fracking" is a proses where an energy company injects fluid into drilled holes, fracturing oil shale rocks. This process releases natural gas and methane, which the energy company uses for fuel. This gas can also; however, seep into the ground water and wells, polluting our very own tap water.

This recent event shows how people can easily pollute our own fresh water systems. The chemical company Freedom Industries showed disregard for the protection of water in Charlestown West Virginia. When the chemical 4-methylcyclohexane methanol seeped out of a chemical container into the Elk River, over 300,000 people were left without usable water. This event shows how we are diminishing our fresh water sources through pollution and not just overuse.

This is a really cool video about a sustainable city. The Abu Dhabi Government created a sustainable city near Dubai, In the United Arab Emirates.
