Human noise pollution in ocean can lead fish away from good habitats and off to their death

The growing amount of human noise pollution in the ocean could lead fish away from good habitat and off to their death, according to new research from a UK-led team working on the Great Barrier Reef.
After developing for weeks at sea, baby tropical fish rely on natural noises to find the coral reefs where they can survive and thrive. However, the researchers found that short exposure to artificial noise makes fish become attracted to inappropriate sounds.
In earlier research, Dr Steve Simpson, Senior Researcher in the University of Bristol’s School of Biological Sciences discovered that baby reef fish use sounds made by fish, shrimps and sea urchins as a cue to find coral reefs. With human noise pollution from ships, wind farms and oil prospecting on the increase, he is now concerned that this crucial behaviour is coming under threat.
He said: “When only a few weeks old, baby reef fish face a monumental challenge in locating and choosing suitable habitat. Reef noise gives them vital information, but if they can learn, remember and become attracted towards the wrong sounds, we might be leading them in all the wrong directions.”

If we don't change our ways soon...
A new report by the Royal Society, chaired by Nobel prize-winning biologist Sir John Sulston warns that world population must be stabilized and consumption in wealthy nations must be reduced or the entire planet is in big trouble. As the report reads: "The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future."This is the same warning that President Jimmy Carter gave Americans back in the 1970's - but it was ignored when Ronald Reagan came to power with a "more positive" message basically telling Americans we can do whatever we want. And then after 9/11 - Bush told us all we should go shopping and consume ever more.And now with corporations calling the shots in Washington - long-term sustainability of the planet takes a back seat to short-term profits. If we don't change our ways soon - and embrace clean, alternative energy and educate women around the plant - then we all could be headed for a rough century.-Thom(Is there any chance we will learn in time?

The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness.
