Part 1: It Comes from the Sea
http://marinebio.org/oceans/ocean-resources.asp
1. List the important services the Earth’s ocean systems provide us with.
Food, Removes Carbon to give us Oxygven, Minerals, Histoy, Travel, Shipping, Oil, Regulates Earth's Climate.
2. Define the word fisheries.
All the fishing activities in the ocean.
3. What is a major crisis facing the world’s fisheries?
Economy, Management Practices, and Overfishing.
4. What do you think would be the best solution to the problem?
They need to make more awareness of this crisis, because not many people know about it. Some people might not even know that they are overfishing or hurting the ocean.
5. What is one way the oceans impact the world climate?
It circulates more heat, water, and carbon dioxide than the atmosphere.
6. A very important organism from the ocean called Phytoplankton.
Phytoplankton produces approximately 90% of the world's oxygen.
Part 2: Different Effects Humans Have on the Seas
http://www.eco-pros.com/humanimpact.htm
1. What are some examples of negative effects humans have on the oceans that would
be from runoff?
Killing Marine life, threatens human activity, toxic algae bloom.
2. The article says carbon emissions from the atmosphere are raising the acidity of the
oceans. How is this possible?
It's caused by burning fossil fuels.
3. What is a “Floating City”
A cruise ship is called a Floating City.
4. Approximately how many gallons of sewage do cruise ships produce a day?
30,000 Gallons of sewage every day.
5. How is human waste water or black water harmful to ocean systems?
It can carry bacteria, pathogens, diseases, viruses, and intestinal egg parasites which can poison and harm fish and other ocean organisms.
Part 3: DDT

1.Despite its ban, DDT still appears in the tissues of Antarctic Penguins.
2.How do scientist believe this chemical is still being exposed to the environment after
almost 30 years?
A. illegal use
B. leaking from storage containers
C. melting glaciers
3. Describe the process of bioaccumulation and how it lead to DDT effecting penguin
populations.
When the penguins eat the fish that ate the phytoplankton that filtered the DDT, they got the DDT in their tissues. The affect of the DDT made the penguin's eggs thin and they broke more easily.
Part 4: Rigs to Reefs
1. Describe the benefits of artificial reefs.
Some fish will become residents of the reef, and larger fish will move there to eat them. It also provides hard surfaces for plants to attach to.
2. What is a benefit of artificial reef programs for people?
People can get jobs building reefs, it can become a tourist attraction, and then they will be able to fish there.
3. What is a benefit of the programs for the inhabitants of the gulf?
They can get jobs building reefs, and they can fish the sealife that now live there.
4. List the artificial reef programs currently being utilized by Texas Parks & Wildlife:
SHIPS-TO-REEFS, NEAR-SHORE/SHALLOW REEFS, and RIGS-TO-REEFS.
5. The Rigs to Reef program involves the recycling of obsolete petroleum platforms into permanent permanent artificial reefs rather than allowing them to be taken ashore as scrap.
6. Why do these decommissioned rigs make ideal reef habitats?
Because there are many small spaces for fish to live and for algae to grow, but there are also holes in the ship for them to swim through.
