  • as it flows across roads, yards, farms, golf courses, parking lots and
  • construction sites.

AIR POLLUTION

  • Air pollution doesn’t just cloud the air we breathe.
  • It also harm our land and water.
  • What goes up must come down, and pollution that is in the air
  • Comes back down and winds up in our water way.

AIR POULLTION

  • Atmospheric deposition occurs in several stages.
  • First, pollution is emitted into the air, where wind and weather can carry
  • carry it over long distances.
  • Eventually, airborne pollution particles fall onto the land or into the
  • the water, sometimes in the form of dry particles

STRIPED BASS

  • Striped bass are a key predator in the Chesapeake Bay food web
  • They also support one of the Bay's most popular commercial and
  • recreational fisheries.
  • they must have enough prey primarily menhaden and bay anchovies
  • available to them to keep their population healthy

STRIPED BASS

  • Strong fluctuations in the number of striped bass
  • In the bay could cause cascading changes throughout the rest of the
  • the food web.

BLUE CRABS

  • As both predator and prey, blue crabs are a keystone species
  • in the Chesapeake Bay food web.
  • Blue crabs also make up the most productive commercial
  • and recreational fisheries in the Bay.

BLUE CRABS

  • Blue crabs are prey for fish, birds even other blue crabs!
  • During the past 60 years, blue crabs along with Atlantic menhaden
  • Blue crabs enhance salt marsh communities by feeding on
  • on marsh periwinkles.
