3. Top 5 Endangered Marine Species
1. Bluefin Tuna
2. Cape Penguin
3. Coral
4. Gray Whale
5. Hector’s Dolphin
4. Bluefin Tuna
Known as the most valuable fish
in the ocean
Tuna are a very important food
source for humans
Only 25,000 remain
Cause of endangerment:
overfishing, tuna ranching, loss
of prey
Removal of this species and
others, such as the shark, can
degrade marine habitats
5. Cape Penguin
AKA the “Jackass Penguin”
because of their call that
sounds like a donkey
Endangered because of oil
spills, loss of nesting sites and
loss of food due to overfishing
6. Coral
Very important sea animal
Protects and gives creatures a
place for breeding/spawning
Pharmaceutical properties
In danger because of ocean
acidification and bottom
trawling commercial fishing
7. Gray Whale
Known worldwide for their fierceness
Ones located near Baja California
tend to be friendly
Overfishing is the main cause of their
endangerment
North Atlantic population is extinct
Fishing restrictions have allowed the
Eastern North Pacific to grow
8. Hector’s Dolphin
Only 7,400 left off the coast
of New Zealand
Reasons for endangerment:
bycatch, boat disturbance
and pollutants
9. We are their #1 cause of
endangerment!
By the effects of
pollution, overfishing, boat
ing, oil spills, etc., it is clear
that we are the ocean’s
biggest threat to life.
10. Overfishing
and Pollution
Overfishing and pollution are the two
main issues concerning the
destruction of marine life
75% of all fisheries are overfished, and
if this rate keeps going as is, there
will be no more fisheries by 2050
Pollution of the ocean is a major
problem and is done through many
different ways
11.
12. Not only are we endangering
marine animals, but their
environments, as well.
13. Coastal Dredging Projects
The project that created this
upscale community on Roanoke
Island in North Carolina can
significantly alter wetland
ecosystems, disrupting animals’
habitats and interfering with a
marshland's natural ability to
control inland flooding.
14. Another way to destroy a habitat
is simply by killing off the species
which inhabit the area. For
example, 40 million Thresher
Sharks are killed each year, just
for their fins. Removal of
predators such as these can
destroy the environment.
15. Bottom Trawling
Bottom trawling is a form of net
fishing that scrapes the ocean
floor. This damages habitats by
ripping up coral reefs. Bottom
trawlers also collect large
amounts of bycatch that is simply
thrown back to sea or left to die.
17. Who wants 75% of our world to be polluted?
Activities such as boating and snorkeling are leisure activities and
are a main source of income through tourism for many places
Hundreds of marine species, such as fish, lobster, squid, etc. are
a main food source for people all over the world
It is said that at the rate we are going, by 2050 there will be no
more fisheries. In the United States alone, the international
trade in coastal and marine fisheries contributes $70 billion
annually to the economy
This would not only hurt economies around the world, but also
some peoples’ way of life
Etc.
And most importantly…
20. Expected Learning
Outcomes
1. What are we, as
humans, doing to hurt the
ocean’s environment?
2. How do these things
endanger marine life and their
habitat?
3. Why should we care about
the ocean’s environment?
(How does it effect us?)
