Global Warming Threatens Marine Life." Global Warming Threatens Marine Life. N.p., n.d. Web. 08 Mar. 2013. Current Situation Marine Life - Oceans cover 70% of the earth’s surface
- Two- thirds of marine life is endangered
- Humans are constantly fishing, not letting the population rise again
- 9 billion people by 2050
- 9,000 to 10,000 tons of fish are fished per hour
- 80 – 90 million tons of fish are fished per year
Biggest fisheries:
1. China
2. Peru
3. Indonesia Dangers - 3 biggest threats to marine life:
- overfishing
- global warming
- pollution: Solutions Consumption - global fish consumption: growing by 3.6% every year
- human pop. growing rapidly
- marine resources are decreasing
Top 4 consumers:
1. China
2. Japan
3. USA
4. Australia - 70% of the world's fish species are either extinct or endangered
- Not letting the marine life reproduce and grow
- Cut down on our use of marine resources
- Enforce responsible and sustainable fishing
- Reflect on us as humans: if they die, we die; they are important to us THANK YOU Introduction - Countries close to ocean consume more fish, landlocked countries consume less Pollution - oceans have been treated like sewage dumps
- human population increasing rapidly - more pollution, much of it ends up in the ocean
- top two major pollutants are toxic waste and chemicals
- trash and chemicals in the ocean water it becomes difficult for the marine life to breathe
- animals choke on garbage because they think its food
- when toxic waste harms one organism; it will end up harming a whole food chain of marine life Coral reefs - rainforests of the ocean (biodiversity)
- dying at an alarming rate
- 25% have disappeared already
- biggest threats:
- pollution
- disease
- global warming, ocean temperature rising Examples of Individual Species - one third of all shark species are at risk of extinction
- six of the seven species of marine turtle are threatened
- whaling is still a big issue - blue whales of the Antarctic are at less than 1% of their original abundance
- 5% of North Atlantic fish are left
- 6% of tuna are left, due to overfishing - Reduce the capacity of global fishing fleets
- Eliminate harmful fishing subsides
- Make marine reserves, which are the underwater counterpart of national parks or nature reserves
- Eliminate illegal, unregistered and unreported fishing.
- Double check ships before takeoff to make sure they won't spill oil into the ocean
- Stop all plastic debris, because it strangles/ harms marine life such as fish, dolphins, sea turtles, sharks, dugongs, crocodiles, sea birds, crabs, and other animals too
- Stop noise coming from the ships above because it can affect the marine life
- Stop toxins such as radioactive waste to enter these waters
- Stop commercial whaling in all forms Conclusion - Seafood is a huge part of our diet
- Other resources are used for countless different things in our everyday lives
- Resources are being used up faster than they can be replenished Already, companies and organizations around the world are trying to protect marine life and enforce sustainable ways of fishing. Global Warming - Already threatened by a number of human activities
- Pollution affects global warming
- Global warming is killing lots of sea animals - water is too warm
- Carbon dioxide increasing and sea level rising
- When ocean absorbs co2, chemical reactions create carbonic acids Overfishing - One billion people rely on fish as a key source of daily protein
- 70% of the world’s fish species are either extinct or endangered
- When one species is overfished, it affects the whole ecosystem
