The world's ocean covers about 70% of the Earth's surface. It is use to produce
us many things. It is more than a place to swimming, sailing and other
recreation. The ocean serves as a source of energy, raw materials and most of
all food like fish and seaweed. In this essay I will talk about "What are our
ocean resources and the importance of the oceans in the future."
First, our largest resource in the ocean is food. There are two different kinds
of food in the ocean, such as marine plants and marine animals. These two kinds
of resources are reborn resources and it will never be end. For marine plants we
have the algae's family, like seaweed. During ebb tide, you can find the seaweed
between rocks. For the marine animals we have fish and shrimp. The fish and
shrimp are always moving around the ocean and follow the ocean currents.
What is ocean current? It is a movement of ocean thatcan buring the fish to
other places. There are two kinds of circulation create the currents in the
ocean. They are (1) wind-driven circulation and (2) Thermohaline circulation.
Wind-driven circulation result from the wind sets the surface waters into motion
as currents. The currents generally flow horizontally-that is parallel to the
earth¡¦s surface. The wind mainly affects only the upper 100 to 200 meters of
water. However, the flow of wind-driven currents may extend to depths of 1,000
meters or more.
Thermohaline circulation produces great vertical currents' hat flow from the
surface to the ocean bottom and back. The currents largely result from
differences in water temperature and salinity. The currents move sluggishly from
the polar regions, along the sea floor, and back to the surface. In the polar
regions, The surface waters become colder and saltier. Being colder and saltier
makes these waters heavier, and they gradually flow back toward the surface and
replace the surface waters that sink. For example, as a warm ocean current and a
cold ocean current meet together, The warm water will always follow cold water
and moving around the ocean. The most important is the plankton does not like to
stay in the cold place. They will follow the warm current. As the result the
small fish like shrimp that eats plankton, will follow the plankton. Similarly
the bigger fish that eats small fish and shrimp will just follow also and these
fish...

Change salt water to clean water is very easy. The scientists invent a machine
which can change the salt water to clean water. First, you have to boil the salt
water and wait until the salt water become steam then the salt will be left in
the container and wait or the steam become clean water.

Corals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish, 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the foundation of marine life, and this also means that they are essential for human life, but all over the world they are dead or dying because people are destroying them at a very fast rate. Already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 years unless people stop doing what they are doing now – i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.
An attractive child still in school is a child until they turn eighteen. The idea that any adult or older peer could find them in the least bit distracting or attractive because of their body being show is horribly creepy. The dress code supports the idea that a student’s body is shameful, therefore, objectifying. Those with opposing views may claim that the dress code is helping education because they do not focus on their looks, just their studies. To show, from 18 Significant School Uniform Pros and Cons, “Because a school uniform limits the options a student has for clothing, there is less pressure to get through the morning routine. This often allows students to sleep a bit more because less time is required to get ready.” Though this is completely true, the most prominent idea of a uniform is to make sure a student is properly covered. Uniforms are a way of objectifying girls and boys alike, so there is at least no unfairness within the concept of gender. Still, there is lack of logic to why anyone should be required to cover up, as if it makes adults feel uncomfortable. Teaching both adults and children to respect those of all ages is imperative. Treat others how they should be treated: appropriately. From a first-hand account, Lindsay Merbaum, a teacher, “Male colleagues would sometimes approach me and point out the offending ensembles, as they felt uncomfortable addressing female students about their attire. I didn’t blame them — there’s something unseemly about telling a teenage girl that what she is wearing is wrong. It reveals that you’re looking at her closely, that you’re looking at her body, that her body is offensive.” Many people could agree that no adult should look at a child like they look at someone their age. It’s extremely uncomfortable to feel like a piece of eye candy for those who can
With smiles on our faces we cast our wisely selected lures into the ocean, but we then encountered our first problem of saltwater fishing. Our lures wouldn’t sink. As soon as they hit the water, the ocean current would just buoy them to the surface and, soon after, down current into the line of a nearby fisherman. Improvising our rigs, we dug the heaviest weights out of our tackle boxes and clamped them onto our lures. Sure enough, we got our lures underwater and under control.
Surface current are found in the upper four hundred meters (400m) and makes up about ten percent (10%) of ocean (Briney, n.d.). Surface ocean currents are as a result of friction between the water and atmosphere interface. The wind exerts a force or stress to the ocean surface and causes the water to move. The winds that most affect the oceans’ currents are the Westerlies which produce belts of ocean currents that flow east in the mid-latitude and the Trade winds which generate currents that flow to the west in tropical latitudes. These winds are mainly a result of warm air from the tropics moving towards the poles. The direction of the current is not the same as the direction of the wind but it is deflected at a forty five degree angle. This deflection is resulted from the earth’s rotation on its axis called the Coriolis force/ effect. Coriolis force and constrains by continental land masses cause surface currents to develop into an alm...
Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to discover.
• Understand the movement of fish. Since small water bodies have limited oxygen supply, fish tend to stay shallower. On the contrary, fish in larger lakes have adequate oxygen supply; hence, fish tend to stay where there is food. The fish may also stay deeper because the temperature of the deep water is slightly higher.
The beginnings of any type of dress code come from social structures around the world. Dress codes were very important in distinguishing the different classes of citizens in society. In the past, dress codes have changed and eventually became commonplace in our educational system. Private schools have set rules in place on what students need to wear and some girls’ schools expect their student body to wear uniforms and even went as far as inspecting socks and fingernails each morning before they started their day (Elizabeth Crook, 2004). The Long Beach Unified School District is recognized as the first public school system to implement a dress code in the United States. Many schools followed in their footsteps and the controversy over dress codes and people being ready to conform to these rules had begun.
While a beautiful sunset on the beach can be astounding, a spectacular scene is not the only benefit oceans provide. Without the oceans, we would not have adequate amounts of oxygen to breathe or enough protein to eat. The Earth's climate would not be inhabitable for human beings and many animals. The oceans supply medicines, food and drinking water which arise from ocean processes. Out of the five oceans, the Pacific Ocean is the world’s largest and deepest ocean. It spreads over an area of 165.2 million square kilometers. More than 25,000 islands float within the Pacific. Within the Pacific Ocean lies an unusual island, an island that is more than twice the size of Texas and is earth’s largest landfill, the Great Pacific Garbage Patch (McLendon). Society is unaware that the excess use of plastic and other non-biodegradable materials has ended up in the middle of the Pacific Ocean and is the main source of ocean pollution. The solutions, ranging from manual clean-up to eliminating any further obliteration to the Garbage Patch, will reduce the amount of effluence the world has to endure.
Sharks are known as one of the most fearsome creatures that end innocent peoples' lives with no mercy, however, there is a large amount of information that civilians do not know about them. This year alone, sharks killed a total of twelve humans worldwide. On the contrary, this is compared to a killer amount of "100 million sharks that were killed this year by the actions of humans" ("Shark Finning"). In addition to these startling numbers, the killing of sharks actually damage our ecosystem just because of this known persona that all sharks are wicked and not help in any way towards the environment. There are quite a lot of positive factors and interesting facts about sharks that make them appealing towards learning more about these majestic creatures. Overall, it is important to feature interesting facts about sharks because of how society displays a stereotypical flaunt of sharks, yet there are respectably well factors of sharks and their input in the dark sea.
It includes the water found in lakes, reservoirs, and groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today.
Earth is the only planet in the Solar System that has liquid water. The ocean contains ninety seven percent of the earth’s water and covers almost three quarters of the planet. There are four different oceans, the Pacific, Atlantic, Indian, and the Arctic. Tides and currents occur in all three of these oceans. Many different kinds of fish and mammals also make their homes in these oceans. All of these oceans are connected to each other in some way. Humans find oceans to be very interesting, beautiful, and exploring.
In a research article by Lotze, Coll, Magera, Ward and Airoldi (2011) they examine the positive side of how ecosystems in the ocean can recover even though they are faced with many different types of struggles every day. The authors ask the main question: How common is recovery among depleted populations and degraded ecosystems in the ocean? It is hypothesized that over the years, ecosystems are going to recover and essentially in the future, increase. The results in this study supported the hypothesis of the research on recovery for certain ecosystems and stated that 10-50% of ecosystems actually show some rate of progression (Lotze, 2011). This has significance when looking at pollution and the effect...
