Nutrients in the Bay
The Chesapeake Bay has pollution. Some of it is from
toxic compounds, such as mercury.
How can we connect this to prior knowledge?
Use the space below to create an analogy for the
amount of nitrogen and phosphorous in the Bay.
Surprisingly, too much nitrogen and phosphorous also
cause pollution. Without nitrogen and phosphorous
plants and animals wouldn’t exist.
too much food
obesity
=
too much nitrogen or phosphorous
How can we help?
Why is this a problem?
Blooms and odors
Loss of oxygen in water – habitat loss
Decomposition
Decreased water clarity
Loss of seagrass
Where is all of it coming from?
1) Agricultural Uses
2) Housing Developments
 leak nitrogen and phosphorous from fertilizer
and dog waste
3) Treatment of Wastes
4) Power Generation
 acid rain
 car emissions

1) Agriculture
 plant cover crops to soak up unused nutrients
 keep animals out of waterways
2) Housing
 use less fertilizer and use at the right time of
the year
 pick up dog waste
 install rain gardens
3) Power Generation
 emit cleaner gasses
 decline in nitrogen falling from
sky
What other ideas do you have?
