Landfills

 
     A landfill is where waste can be disposed. One type of landfill is a sanitary landfill. This landfill actually helps the environment. How? The people seal the garbage away. The second type is municipal solid waste. This is also like a sanitary landfill, except it holds more of our household waste.               The opposite is unsanitary. This landfill can affect human life and the environment health.                                                                         
    Landfills can be used in many ways. In fact, the gases in a landfill, like methane, can be used to heat our homes, or gives us electricity. But these gases can be minor. To produce this methane gas and others, H2O and oxygen go into the dirt covered pack. Once that happens, the gases go out doing their evil mission: hurting the atmosphere. But in a sanitary landfill, operators have to control the H2O and oxygen. If operators cover the pack too early, the pack too early, the pack will go down and pollute for a long time. Lastly, the gases produce the odor of the landfill.

            There are a variety of reasons landfills are harmful to the environment. When a landfill breaks down, it takes many, many years to disintegrate. Years…years are bad. Like I said, it produces many gases to harm the atmosphere. These gases contribute to different climate changes. Also if the landfill pack is covered too early, it is also polluting the ground and air. Humans keep putting garbage into landfills. The more the garbage, the more the world is having weird climate changes. And negative effects to our environment.
