Sharks play a very important role in the oceans in a way that an average fish does not. Sharks are at the top of the food chain in virtually every part of every ocean. In that role, they keep populations of other fish healthy and in proper proportion for their ecosystem.  How do sharks keep the oceans healthy?

Sharks keep food webs in balance

Sharks have evolved in a tight inter-dependency with their ecosystem. They tend to eat very efficiently, going after the old, sick, or slower fish in a population that they prey upon, keeping that population healthier. Sharks groom many populations of marine life to the right size so that those prey species don’t cause harm to the ecosystem by becoming too populous. 

The ocean ecosystem is made up of very intricate food webs.  Sharks are at the top of these webs and are considered by scientists to be “keystone” species, meaning that removing them causes the whole structure to collapse.  For this reason, the prospect of a food chain minus its apex predators may mean the end of the line for many more species.  A number of scientific studies demonstrate that depletion of sharks results in the loss of commercially important fish and shellfish species down the food chain, including key fisheries such as tuna, that maintain the health of coral reefs.

Sharks keep prey populations healthy

Predatory sharks prey on the sick and the weak members of their prey populations, and some also scavenge the sea floor to feed on dead carcasses.  By removing the sick and the weak, they prevent the spread of disease and prevent outbreaks that could be devastating. Preying on the weakest individuals also strengthens the gene pools of the prey species.  Since the largest, strongest, and healthiest fish generally reproduce in greater numbers, the outcome is larger numbers of healthier fish.

Sharks keep sea grass beds and other vital habitats healthy

Through intimidation, sharks regulate the behavior of prey species, and prevent them from overgrazing vital habitats.  Some shark scientists believe that this intimidation factor may actually have more of an impact on the ecosystem than what sharks eat.  For example, scientists in Hawaii found that tiger sharks had a positive impact on the health of sea grass beds.  Turtles, which are the tiger sharks’ prey, graze on sea grass.  In the absence of tiger sharks, the turtles spent all of their time grazing on the best quality, most nutritious sea grass, and these habitats were soon destroyed.  When tiger sharks are in the area, however, turtles graze over a broader area and do not overgraze one region.

An important lesson: we need sharks!

Where sharks are eliminated, the marine ecosystem loses its balance.

In the parts of the ocean where sharks have been fished out of existence, we can see the dangerous result of removing the top predator from an ecosystem.

The lesson is important. Sharks are being killed for their fins for shark fin soup, a food that has assumed cultural value but is not important for human survival or health. However, removing the sharks can result in the loss of important foods that we do depend upon for survival.

Sharks have survived for 450 million years, but may be gone within the next decades. Life within the oceans, covering 2/3rds of our planet, has enjoyed a relationship with sharks for about 450 million years. Our growing demand for shark fin soup has increased the slaughter of sharks to such a great extent that many shark species are already nearing extinction.

What will the health of oceans be like when such an important group of animals have been destroyed? Do we want the destruction of sharks and the oceans to be the legacy we leave for our children?

What You Have To Know About Shark Fin

Looks so tasty, right? Shark Fin Soup is a popular soup item of Chinese Cuisine usually served at special occasions such as weddings and banquets, or as a luxury item in Chinese culture.Demand for the soup has increased as income levels of Chinese communities worldwide have risen. International concerns over the sustainability and welfare of sharks have impacted consumption and availability of the soup.

In shark fin soup, the fins themselves are virtually tasteless. The taste comes from the soup, while the fins are valued for their texture. Keith Bradsher of The New York Times describes it as a “chewy, sinewy, stringy” texture.Krista Mahr of TIME called it “somewhere between chewy and crunchy.” Dave Lieberman of OC Weekly wrote that it is a “snappy, gelatinous texture”. Most westerners’ reaction to eating shark fin for the first time is that it has almost no taste. However, texture is prized as much as taste in Asian cuisine. 

but, can you see that there’s an endangered species in your bowl of soup? 

All of this killing for a bowl of soup! Shark finning is not only a cruel and backwards practice, it is a waste and a travesty on nature and must stop before the great equalizer of the sea is lost forever.

Mankind cannot continue to abuse nature or nature will strike back… and with brutal fury! Shark finning should be made a practice of the past so that children will be able to see and admire sharks in the future… for it would be a sad and tragic day when the only sharks people get to see are the ones in books.

Its important to remember also, that mankind will become extinct next if sharks disappear. Without sharks the oceans will team with fish and other ocean animals that live off the plant life in the sea. When this plant matter disappears so will the vital oxygen that the ocean produces… than what happens? Think about it.

Pressure from the public resulted in a international moratorium on whaling, but there are no international regulations to protect sharks.

Shark supplements are used in Asian countries to cure everything from intimacy dysfunctions to cancer. The facts: sharks get cancer and like many creatures in our oceans are contaminated with high levels of mercury.

enaknya menjadi bodoh, kamu tidak perlu mencari cara pintar yang terkadang jadi sulit untuk kamu kerjakan, bahkan untuk dirimu sendiri. karena memang pada suatu waktu, tidak perlu menjadi pintar untuk mengerti hal hal yang mungkin susah untuk kamu mengerti…just go with it! aku yakin hidupmu akan kehabisan waktu untuk memahami hal hal tadi dan akhirnya berakhir dengan melewatkan kebahagiaanmu sendiri. apa yang bisa lebih mengenaskan daripada itu semua? just keep the answer for yourself then…

Rindu Yang Tak Seperti Yang Kita Duga

ketika dalam sebuah perjalanan yang terlihat begitu panjang,

kenapa tidak kita memutuskan untuk berdamai dengan rasa rindu?

rasa rindu yang ternyata tidak seburuk yang kita kira

rasa rindu yang membenarkan segala bentuk kesabaran

rasa rindu yang memeluk segala kekhawatiran

rasa rindu yang memelihara pengharapan

rasa rindu yang memberi penguatan

rasa rindu yang mengikhlaskan yang tak terikhlaskan

rasa rindu yang menciptakan kebahagiaan dengan rupa lain

rasa rindu yang menghangatkan kebekuan ego

rasa rindu yang menyimpulkan senyum tanpa tersentuh lara

rasa rindu yang membebaskan dari dengki

rasa rindu yang pada akhirnya begitu menyamankan hati

i miss being at home,

spending some times with you

two cups of tea

bag of stories

spoonful jealousy

cart of laugh

frame of blue skies

the anxiety

menyenangkan akhirnya memasuki fase seperti ini,

dimana terkadang harus ada perlawanan, ada kalanya ikuti saja arusnya.

yang jelas satu yang harus dipunya, hati yang teguh….

lebih mengerikan jika disaat seperti ini kita tidak bisa menentukan pilihan,

tapi juga harus siap dengan segala akibatnya.

masalah akan menjadi masalah kalau kita menganggapnya sebagai masalah,

jika sebaliknya maka ini adalah hal paling menyenangkan yang harus dilewati.

anggap saja ini adalah suatu proses untuk lebih mengenal diri sendiri

anggap saja ini proses untuk lebih tahu cara terbaik menyelesaikan sesuatu

anggap saja ini pembiasaan dikemudian hari jika harus bersinggungan dengan hal seperti ini lagi

anggap saja ini harta untuk kita bawa demi kebaikan suatu hari.

terkadang kita hanya terlalu sibuk menuliskan hal hal yang kadang kita sendiripun tak tahu tentang apakah hal itu, tapi kita tetap saja menulisnya hanya untuk sebuah harapan akan suatu saat kita akan memahaminya. 

dear, my baby

i know i might not that much fun to be with

but baby when it rains, i might be the one who shelter you

i know i might not that much fun to be with

but baby when it’s cold outside, i’ll give you warmth inside

i know i might not that much fun to be with

but baby when your world comes so hazardous, i’ll calm you this night and the night after
