The Big Idea: Noisy Ocean - National Geographic Magazine

To read an article which discusses the fact that the noise made by humans is adversely affecting life which resides in the oceans of our planet, please click on the link above this sentence. To read a report about Ocean Noise which was created by the International Fund for Animal Welfare please click on the following link:

Note: You need a program on your computer which can read PDF files to access the above-mentioned-article.

From the article:
"Ocean noise pollution is also being linked with behavioural
changes that have been seen in marine animals around the
world, including the abandonment of preferred habitat,
alterations in surfacing and diving patterns and in the types,
timing and volume of calls. At least some cetaceans are
known to have changed their calls as they struggle to make
themselves heard. Ocean noise pollution may also be behind
incidences in which marine animals have abandoned vital
activities, such as feeding. It may even be causing fatalities:
high intensity military sonar is implicated in the deaths of
beaked whales and mass strandings of cetaceans around
the world."

Wow,it seems Humans have created even more problems in the Oceans of this planet for those life forms which live there!

 Here is a video I found at Youtube discussing the problem of excessive noise in the Oceans of the World:

Here are some websites which discuss this problem in greater detail than I can in this blog post:

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.
