Reefs at Risk!!! (Revised 2)
Do you still remember the sensational “best job in the world” in
2009? Tens of thousands of outstanding
candidates the world over participated in this ferocious wild-card competition, merely to grasp this once-in-a-lifetime chance
and experience--- to be an island caretaker and promote the remarkable
World Heritage site, the Great Barrier Reef Islands
in Australia, to the public. The ones who competed in getting the precious wild card would get the privilege to live in
the high-end resort on the island for free and if chosen to be the winner, he
would be paid fairly high. Although the criteria for the suitable promoter were
extremely strict and tough--- the prerequisites, for
instance, were advanced proficiency in English, enthusiasm in interpersonal
relationship, outdoors activities, and excellent swimming and snorkeling skill,
I still dreamed to be one of those impeccable candidates. Imagine myself immersed in the
ambience of a carefree island, enjoying the
bright warm sunshine, plunging into the
turquoise crystal clear ocean and feasting my eyes with the wonderful splendid undersea world, along with colorful schools
of fishes swimming by in droves and gorgeous corals swaying as beckoning. It is always my
dream-to-realize, for I love the azure ocean so much!
Nonetheless, I doubt if I have the luck to
explore this spectacular wonder in the future.
You
must be curious about the underlying meaning I am referring to. Actually, not
only the Great Barrier Reef but also other islands
composed of reefs are at the brink of extinction. Take Republic
of Kitibati, a petit country composed of reefs and located in the Pacific Ocean , for example, residents there are even forced
to leave their hometown due to the sinking of
the coral-based island. By pursuing the growth of economy, we are at the
same time exhausting and devastating the nature.
We devote ourselves to the development of the industry yet
simultaneously, we downplay the risk and cost we have brought to our mother Earth. The consequence is that our world is
not as beautiful as before and many creatures are endangered, inclusive of the coral reefs.
Like “rainforests on land” are facing the threats of logging and deforesting, those
“rainforests of the sea” are doomed to deteriorate because of the excess use of
natural resources.
“Reefs at risk” has been an important issue nowadays because it
affects the whole ecosystem. Reefs are home to millions of animals and they
serve as a buffer holding back waves during hurricanes. By and large, they are the vital anchor that supports
the entire system. As a consequence, once we lose these coral reefs, the
eco-system breaks down and so in order to sustain biodiversity and keep this
extraordinary beauty under the sea for future
generations, we have to cut directly into the point and examine the key
contributors that result to the coral’s deterioration.
The causes of the coral’s demise are manifold but they derive from the same
culprit--- human. It is we that make the condition
worse. By sorting all
the listed causes that would lead to massive coral killing, we could categorize
them into the four main factors: Warmer oceans, pollution of the water supply, overfishing and carbon dioxide
problem.
Firstly,
when it comes to global warming, it undoubtedly poses an extremely severe
threat to the survival of the coral reefs. That is, the warmer the water, the
whiter the corals. If we cannot stop the climate change and lowering the
keep-rising temperature, the dazzling coral reefs would vanish for good. When the water heats up above a certain
degree, the colorful algae inside the corals would be forced
to expel out of the body and reefs would undergo bleaching process then die as soon as possible. Secondly, the excess
emission of carbon dioxide is a fatal contributor as well. Carbon dioxide has a great impact on the ocean in that the
unabated rising of carbon dioxide has turned the ocean more acidic. The corals’
calcium carbonate limestone skeleton would merge
with carbon dioxide and thus break the formation of the corals, making them utterly vulnerable. Thirdly, pollution
of the ocean water brings about the so-called eutrophication,
caused by the enrichment of chemical nutrients from fertilizer or sewage. These
toxic chemicals lead to the fast-growing of seaweed and
those seaweeds would cover the surface of the ocean and smother corals
by blocking sunlight, which is a pivotal source for
plants to produce nutrition. Another cause that results in water pollution is
the oil contamination from the ships. The occasional oil spill would spread at
a large scale and thus ruins the entire reef system and marine life, destroying
the biodiversity. Last but not least, the overfishing issue. Overfishing
dwindles fish stocks. When the reef’s colorful grazers, the fish, are taken
away, the seaweeds take over and thereafter isolate the
underwater world from sunshine. In addition, the
fishermen often use anchor chains instead of moorings to stop the ships and
that would tear the coral branches apart.
Corals
reefs are indeed the dominant
architectures of the gorgeous wonder of the ocean. In order to sustain this breathtaking
amazing beauty, we have to take actions to
protect the dying coral reefs. Being one of the members
on the Earth, we need to come up with some ways that we could put into practice
in our common life: Do not purchase jewelry that are made from endangered
corals; Do not touch corals when we go scuba diving or snorkeling because we
might hurt polyps within; Avoid eating fish that is crucial in food chain like
sharks otherwise it would break the balance and bring abundant seaweeds; Apply
biodegradable sunscreen possibly when we go swimming, and wait for a while
before jumping into the water because the ingredients in most of sunblock contain
chemicals that could boost viruses in seawater and block the sun, just to name
a few With all these easy-to-do manners, I believe we could make a huge
difference by doing small. After all, it is never too late to mend!
