Water and Air Pollution is bad for our
world. It destroys animals habitats, kills
animals, and can harm us by hurting
our lungs and contaminating our
drinking water. What can we do to help
stop water and air pollution?
           Air Pollution
• How can air pollution can affect
  animals and plants adversely?
• How does air pollution happen?
• How can we help stop air pollution?
• Air pollution is important because it
  can affect us and aquatic systems that
  we want to protect.
  How Can Air Pollution Affect
 Animals and Plants Adversely?
When we pollute the air the Ozone layer gets thinner.
  Air pollutants called Chlorofluorocarbons (CFC’s)
  destroy Ozone Molecules. The spots destroyed by
  CFC’s are called Ozone holes. When the holes get
  big enough, the sun’s harmful rays (the Ozone
  protects us from them) hurts plants and animals.
Tropospheric ozone harms living organisms. The
  molecules from the troposphere can damage
  animals lung tissue. It can also prevent plant
  respiration by blocking the openings in leaves where
  respiration takes place.
How Does Air Pollution Happen?
In houses and office buildings poor
  ventilation can cause air pollution. In
  urban areas transportation and coal
  burning power plants can cause
  pollution. Burning fossil fuels can also
  cause air pollution.
    How Can We Help Stop Air
Ways we can help stop Air Pollution:
• Walking or biking instead of taking a
• Carpooling
• Avoid spilling gas         Air Pollution

• Use gas powered lawn tools as little as
• Avoid getting products in aerosol spray
          Water Pollution
• How does water pollution affect aquatic
  animals and plants adversely?
• How does water pollution happen?
• How can we help stop water pollution?
• Water pollution is important because it
  can affect aquatic ecosystems
  adversely and we need
  to protect our wetlands.
How Does Water Pollution Affect
  Aquatic Animals and Plants
Water Pollution can affect aquatic
 animals adversely by damaging the
 habitats – making conditions that are
 not suitable for living animals and
 plants. Water pollution can kill animal’s
 prey so they cannot live in that habitat.
 It can also kill human food like fish and
 sea food. It can contaminate their
 drinking water.
      How Does Water Pollution
Pesticides are applied to farm fields and roadsides.
  When it rains ,the pesticides run off down hill and
  into a local stream or creak. This contaminates our
  drinking water and it can hurt the fish living in the
  aquatic ecosystem.
Oil spills can harm aquatic plants and animals. Oil
  spills can also hurt coastal business and fishermen
  because they have no more fish to capture.
Plastic and other litter harms aquatic plants and
  animals. The plastic can entangle fish, sea turtles,
  and other marine mammals. It will also cause pain
  and even death.
   How Can We Help Stop Water
In your home you can:                   Water Pollution
• Properly dispose and recycle trash.
• Use nontoxic household products whenever
• Conserve water – turn off the sink when
  shaving or brushing your teeth, take shorter
  showers, and repair leaks or drips in sinks,
  bathtubs and showers immediately.
In your yard you can:
• Use natural fertilizers – such as compost,
  manure, bone meal or peat.
How Has Water and Air Pollution
     Changed Over Time?
• How has the amount of air and water pollution
  changed over time?
• How long have people been polluting the water and
People have been polluting the air ever since cars were
  invented and factories made products.
• Is the amount of water and air pollution better or
  worse now then before?
The amount of water and air pollution is not that bad
  today. There are still people though that are polluting
  our world.
• Learning about how water and air pollution is
  important because that way we can know more
  about water and air pollution so we can stop it.
       How Has Water Pollution
        Changed Over Time?
Water pollution has changed over time because…
Before the Congress passed the Clean Water Act in
  1965, water was terrible. People threw their raw
  sewage into the River Des Peres in St. Louis. The
  River became very smelly. So, the people of St.
  Louis started a project called the River des Peres
  Sewerage and Drainage Works, and it took nine
  years to complete (from 1924 to 1933). Workers
  paved the River's banks and straightened its bends.
  Elsewhere, the River was directed below ground to
  join with the sewer. In the 1960’s MSD was built, they
  treat waste water (water that comes from your toilet,
  sinks, bathtubs and showers).
 How Has Air Pollution Changed
         Over Time?
Air pollution has changed over time
Before the Clean Air Act our air was not safe
  for plants, animals and humans to breathe.
  The Missouri Botanical Gardens bought
  Shaw Nature Reserve in the 1920’s because
  the air in downtown St. Louis was killing the
  plants. The Clean Air Act is the law that
  defines EPA's responsibilities for protecting
  and improving the nation's air quality and the
  ozone layer.
 How Can We Stop Water and
       Air Pollution?
• Stop littering.
• Don’t release harmful gases into the
• Keep the air and water clean.
• Stopping air and water pollution is
  important so we can save aquatic
  ecosystems from being harmed by
• Mr. Marty Aubuchon – has worked at MSD
  for 24 and a half years. He is a Senior Civil
  Engineer. MSD stands for Metropolitan Mr.
  Sewer District. MSD cleans waste water. Marty
• Mr. Todd Heller – was our tour guide at
  MSD           ME!
• Did you know that water from the storm
  drains go straight to creeks, streams and
  rivers without being treated? Gasoline, oil,
  twigs and grass clippings get thrown straight
  into water which makes the water polluted.
• When your car leaks oil, it gets onto the
  roads. When it rains, the oil goes with the
  extra water as surface run-off. The oil goes
  into streams or other bodies of water and
  pollutes the water.
Lots of people think people are getting
 better at keeping our air and water
 clean. What do you think? How can we
 do even better? We can use the facts
 from this PowerPoint out in the real
 world to make a difference in our world.
