Title: Fresh/Saltwater Fish


1
Fresh/Saltwater Fish
  • By Sara Babakioff

2
Causes of Death
  • Water pollution/toxic wastes
  • Over fishing
  • Global Warming

3
Types of Water Pollution
  • Oil spills, nitrogen, phosphorous, untreated
    sewage, fertilizer, mining residue, and plastic
    waste are all examples of pollution that is toxic
    to fish.

4
Lethal Incident in China!
  • On August 29th, Yongcheng County opened a sluice
    to release water contaminated with both sewage
    and industrial waste into the ocean which was
    stored for a long period of time
  • 450,000 fish died

6
Over Fishing
  • Off sets the natural food chain
  • The whole ecosystem becomes degraded
  • Not enough adult fish can find mates so theres
    not enough breeding
  • Ultimately reduces populations drastically to the
    point of no recovery

7
Reasons for Over fishing
  • The government doesnt intervene
  • Too much profit is involved
  • More jobs available to people

8
Global Warming
  • Climate change will force fish to relocate in
    colder regions up North
  • This will effect the ecosystem balance, fisheries
    and the crucial food source for countries and
    marine life
  • Since theres more fish now in Arctic regions,
    theres an increase of fishing there
  • Stunting the growth of deep water fish by 30
    from 50 years ago

9
Death due to pollution
10
What we can do to help
  • Reduce your ecological footprint!
  • Never pour toxic substances down the drain
  • Use Non toxic substances
  • Buy fish that have the lowest impact
  • Educate others!

11
The Aftermath
  • Over the past half-century, the world's annual
    fish catch has risen from 18 tonnes to 95 tonnes
  • Much of the fish we consume now are poisoned by
    pollutants
  • We are losing species of fish and other marine
    life
