One farmer started using a machine called a digestor to make his cow poop into energy. It was created to that when you get rid of cow poop, it won't pollute the surrounding area. Another reason why it was created was so that the U.S had a newer and cleaner form of energy. He heats his house with this poop energy and he actually gets paid by the electric company. The digestor also can maake bedding and fertilizer. He also saves money by doing this too. The digestor transfors tiny bacteria particles to methane used for power, and leaves a liquid for fertilizer and a solid for anything else used. This process does take at least 20 days but it is still a huge money and energy saver. The only bad thing about the digestor is that they are not sure if it will create a water pollutant from all the run off poop. This can be done with either cow or pig poop. So now you know that cow poop is good for the enviroment. :)
