Endangered Marine Life Allie Carlson McGinley Fall 2011
The amount ofendangeredmarine life ison the rise.
Top 5 Endangered Marine Species 1. Bluefin Tuna 2. Cape Penguin 3. Coral 4. Gray Whale 5. Hector’s Dolphin
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
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
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
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
Hector’s Dolphin Only 7,400 left off the coast of New Zealand Reasons for endangerment: bycatch, boat disturbance and pollutants
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.
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
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 marshlands natural ability to control inland flooding.
Another way to destroy a habitatis 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 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 largeamounts of bycatch that is simplythrown back to sea or left to die.
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 Outcomes1. What are we, ashumans, doing to hurt theocean’s environment?2. How do these thingsendanger marine life and theirhabitat?3. Why should we care aboutthe ocean’s environment?(How does it effect us?)
