Endangered Marine Life

The amount of endangered marine life is on the rise.

Top 5 Endangered Marine Species

Page 4: Endangered marine life  allie carlson

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

Bluefin Tuna

Page 5: Endangered marine life  allie carlson

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

Cape Penguin

Page 6: Endangered marine life  allie carlson

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

Coral

Page 7: Endangered marine life  allie carlson

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

Gray Whale

Page 8: Endangered marine life  allie carlson

Only 7,400 left off the coast of New Zealand

Reasons for endangerment: bycatch, boat disturbance and pollutants

Hector’s Dolphin

Page 9: Endangered marine life  allie carlson

We are their #1 cause of endangerment!

By the effects of pollution, overfishing, boating, oil spills, etc., it is clear that we are the ocean’s biggest threat to life.

Page 10: Endangered marine life  allie carlson

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

Overfishing and Pollution

Not only are we endangering marine animals, but their environments, as well.

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.

Page 14: Endangered marine life  allie carlson

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.

Bottom TrawlingBottom 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.

Why does this matter?

Page 17: Endangered marine life  allie carlson

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…

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?)
