Welcome to Lake McNasty

• The tragic story of a polluted lake.

2

• Once upon a time there was a beautiful lake with
  crystal clear water. It was so clean you could
  see right to the bottom, and all the animals were
  happy. No humans lived around it, until one day
  

3

• ...people from far away came with barrels of
  paint and dumped it into the lake. The paint
  slowly seeped from the barrels into the beautiful
  lake!
• (students dump paint into aquarium)

4

• The lake was getting so dirty you could no longer
  see the bottom. The animals started feeling
  sick. A few weeks later a boat sailed across the
  lake and leaked oil.
• Students dump vegetable oil into the aquarium.

5

• Now the animals were slowly dying off, or leaving
  the lake. Not many were left when along came
  garbage trucks every week dumping trash into the
  lake.
• Every student dumps a piece of trash into the
  aquarium.

6

• By the time humans had moved in to the surround
  lake area, it was so disgusting they started
  calling it Lake McNasty. The once clean
  freshwater lake was nothing but a pit of sludge.
  They were unable to drink it, swim in it, or use
  it for any purpose.

7

• Now the people started to work together to clean
  up Lake McNasty and return it to its original
  state by picking up trash, and stop dumping
  toxins. Slowly the lake started to look better,
  and animals gradually moved back. But its still
  not as clean as it was in the beginning and it
  may never be.
