Everyone wants to live in a clean world, but not everyone wants to help keep it clean.
Animals live in the ocean that is dirty. The sea has oil spills and others contamination. This is
causing animal life to disappear. People can stop all these things if they work together. “Because
of global warming and higher ocean temperatures, scientists report that plumes of methane are
now rising from the Arctic Ocean.”(Hilderman). Sea animals that would eventually become
extinct can be saved if the public changes some bad habits and starts to help make the ocean
clean again because most people don’t care about helping.
There is a huge number of different species in the ocean. Most scientists think life began
in the ocean over three billion years ago. “The greatest concentration of animals was found in
waters that were about fifty to sixty eight degrees.”About over one million known species of
plants and animals live there, and scientist say there may be as many as nine million species we
haven’t discovered. “Worldwide, more than seven hundred species have been discovered near
hydrothermal vents. About seventy five percent of those are thought to occur only around vents.”
Scientist only discovered about ten percent of the ocean, they still have ninety percent left and
the scientist don’t even know more than half of the species in the ocean. “The researchers used a
remote – controlled vehicle that dived about eight thousand feet to gather images and samples
from the sea floor.” Imagine all those different species in the ocean that we haven’t discovered.
“Deep in the southern ocean near Antarctica, scientists have discovered 23 new animal species
living in the hot, dark environment around hydrothermal vents.” (Bhanoo).

Dumping oil into the oceanis a big problem. Oil spill are very bad for the sea animals and
plants. “Crude oil contains benzene and other hazardous chemicals that can cause cancer.” The
water is not clean because of many things; one of them is oil spill. “The oil companies know the
dangers of this stuff, says Miller, as she watches report of cleanup workers gathering up toffee-
think oil with any shovels. Nobody provided the workers with any protection. It’s going to
happen all over again.” We need to do this for them and for us we also need a good and clean
place to live. If there is oil in the ocean there won’t be any plants, and some animals eat plants
for example the Algae so they will eventually die because there is no food for them. “During the
cleanup, their brother Paul was hospitalized after he was knocked unconscious by the fumes
from a plastic bag of oil-soaked wildlife and debris. “It was like he had been gassed”, recalls
mike. Afterward, Paul complained of memory loss, chronic fatigue, and a heightened sensitivity
to chemicals. He was gathering the names of the other ailing workers and contemplating a
lawsuit when he died of a heart attack at the age of forty four.” People may think is not a big
deal but it is. “By the end of the year, state records, Show more than thousand eight hundred
cleanup-crew members had filed for workers compensation, two hundred sixty four of whom
claimed respiratory ailments.” The sea would be so much cleaner if we stop throwing things in
it.(Stranahan).
There are other things that harm animals and plants, like pollution. Garbage has always
been thrown into the ocean, but many years past, and plastic use has increased dramatically.

“Currently, a greater problem to most wild life species than the disposal of plastic waste is the
prevalence of plastic fishing nets.” Recycling reduces the amount of trash that is available to go
into the ocean. “Animals are killed when they ingest or become entangled in the plastic debris.”
Another way is make sure that oil from cars suds from washing, and other pollutants do not go
down your storm drain. “The need for a seabird protection zone is at the moment moot because
the Japanese salmon fishing industry has recently been denied permits to fish in Alaskan waters.”
Just by doing little things to help at least is something, your helping in your own way. “Some
nets that have entangled animals are not inactive use, but are instead “ghost” nets that have been
lost or discarded. These nets continue to capture animals, including birds and mammals.
Although good data on net loss are not available, the amount may equal thousand five hundred
kilometers annually.” Pollution can be reduced a number of ways. “Despite the significant steps
so far to reduce plastic pollution in the seas, congress has not begun to deal with the underlying
issue the proliferation of plastic in our society and the need to substitute biodegradable materials
for plastics.” (Blockstein).
The northern right whales are one of the most sea animals that are fighting for their lives.
“Even though commercial hunting ended nearly 100 years ago, northern right whales haven’t
rebounded the way some other whale species have.” They were killed for a long time now at
least several centuries. Some people are trying to stop this. “Clark says he is amazed at the level
of noise that pollutes the waters and he believes the noise can be another serious obstacle for the
migrating whales.” They live in a cold place but once a year they immigrate to a warmer place
for the females to give birth to calves. “It’s estimated that about only 300 of these giant whales
remain in the Atlantic Ocean, and every year a few more are killed.” The right whales were an

early and favorite target of whalers. “Right whales got their name because they were the “right”
whales to hunt they’re big, slow and float after they are harpooned and killed.” There are other
types of right whales in the world and there is not as much as before of their species.” In recent
years, researchers discovered additional dangers to the northern right whales that may lead to the
extinction of species.” (Neilsen).
The demonic acid is very dangerous for marine mammals and humans that consume toxic
prey species. “The slugs have caused the death of around 15 dogs on Auckland beaches and are
also found in Nelson.” Some species of marine mammals and birds have been affected by
uncommon diseases. “About 30 species carry the toxin in varying. The slugs live on rocks, are
fast moving and will “eat anything” that is around them including each other.” The future needs
to focus in developing countries because disrupting chemicals in humans and wildlife. “After
receiving $750000 of funding for the research, the team is now trying to produce “multiple
generations” of the slugs.” The government is not trying to learn from past mistakes and take
action to control toxic chemicals that harm the citizens, the marine wildlife and people around
the world. (Cooper).
Cynthia Patterson is a teacher here in Smithfield – Selma high. She always knew that she wanted
to be a biology teacher since elementary school. She says that she had a special calling towards
science. She always knew she loved science but she says her senior project opened her eyes to
teach. She is interested in Science is because she believes science answers questions, that she
uses all 5 senses to explore things, and that science is always changing. The most things she
loves about Biology are that we will never know everything so science will never end. The least

5. Rasheed 5
things that she does not like about biology are that there is no quick answer, and that we have to
work for our conclusions. She says to help the animals we have to live more simply, use less,
waste less, recycle more, and know more. In her own opinion there are many efforts to save
habitats but a percentage of people aren’t going to get the job done, she says we all have to do it.
She believes that all science is a challenge, but the ocean poses many obstacles such as storms,
waves, depth, and vast area. Science comes to her naturally.
Sea animals that would eventually become extinct can be saved if the public changes
some bad habits and starts to help make the ocean clean again because most people don’t care
about helping. We all want to have the planet and the oceans clean and safe; if we want it to be
clean and safe for our future we need to be doing something even if you do smoothing thing
small like cleaning the trash from the beach before you leave that little thing would help a lot.
People aren’t thinking of the consequences because nothing big has happened yet. Animals need
our help because they can’t do anything about it, and we need them for so many reasons.
Weneed to act fast and get things better before every animals and plants will eventually become
extinct; the best thing to do is be an example to the people for them to start doing something.
