Ocean

1. Timeline

1.1. Many battles have been fought in the oceans.

1.2. Ocean has been used for transportation for many years and many explorers look for ways to go from the Atlantic to the Pacific Ocean for many years before the Panama Canal was built eventually connecting the two oceans together.

1.3. Many species of new fish keep appearing in the ocean.

1.4. The water cycle renews the water which runs into the oceans.

2. Challenges

2.1. People die from oceans because of the saltwater, drowning and fish/plants that kill them. Also there have been cases where people eat fish and other things that are sick because of pollution making them sick or killing them

2.2. Keeping the oceans clean is a challenge for humans because we produce so much waste. Oil spill and trash kill the wildlife.

2.3. We eat the ocean wildlife and sometimes we over feed and we have to protect the species.

3. Location

3.1. The oceans are Pacific,Atlantic,Indian,and Southern Ocean. The Southern Ocean recently got its name a few years ago

4. Benefits

4.1. Food-It is a major food source for people around the world and the popularity of seafood is increasing.

4.2. Climate Regulation- Ocean dynamics strongly affect climate and weather patterns, transferring heat from the equator to the poles and moderating carbon dioxide levels in the atmosphere.

4.3. Economy: Ocean-related industry provides revenue through fishing, seafood distribution, tourism, recreation and transportation. Seafood has become one of the most exported items in the global market today.

4.4. Transportation: Ocean-bound shipping accounts for more than 90 percent of global trade.

4.5. Medicine: Biomedical products derived from marine plant and animal sources provide important medicinal products and health benefits.

4.6. Recreation: The benefits derived from spending time in and around the ocean are largely immeasurable.

5. Long Term Outlook

5.1. We have to keep the oceans clean and keep them clean.

5.2. We can't over hunt wildlife in the oceans.

5.3. We have to make sure that we keep endangered species and avoid polluting the water that they live in.

5.4. Some medicines are made fro m the plants and fish that come from the ocean, if that disappears so do those.

5.5. Water Treatment Plants could be set up to treat water that is harmful to the enviroments.

5.6. Desalination plants use some of the ocean water and desalinate it making it drinkable to us.
