Study suggests a third of shark and ray species are threatened



"Dr. Jack Musick, emeritus professor at the Virginia Institute of Marine Science, has overseen a global study suggesting that 33 percent of shark, skate, and ray species are threatened with extinction."

"The group's work suggests that 345 of the 1,044 species of cartilaginous fishes studied (33%) are "threatened," a broad grouping that includes species in the "vulnerable," "endangered," and "critically endangered"

This is very bad news for these species. If these species leave our planet, our human existence is threatened! Why is human existence on this planet as a species threatened if sharks species go extinct?


Sharks exist on top of the marine food chain, the disappearance of shark species from our oceans would have cause detrimental effects  throughout the entire marine ecosystem.Plankton makes up 70% of the Earths oxygen. Millions of fish eat this plankton, but luckily the sharks eat and control the population of the fish.. but for how much longer?

 Now I would like to return to the article which indicates that a third of shark and ray species are threatened with extinction. In this article I found the following statements:

"Scientists have already observed the phenomenon off the East Coast from New Jersey to the Carolinas."  The phenomenon which is being alluded to is this:

  "The ray population there has exploded because the sharks that normally preyed on them were overfished. The large numbers of rays in turn gobbled excessive volumes of scallops, decimating the local scallop fishery."

  "A 2007 study in the journal Science outlined this chain reaction."

  "Marie Levine, founder and executive director of the Shark Research Institute in Princeton, N.J., said the area's water quality also deteriorated, because scallops filter water."

"Sharks are critical to the health of the ocean," Levine said.

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
