Professor Frank Gobas, at the Simon Fraser University in British Columbia, has identified a new class of
chemicals which fish seem to be able to get rid of but which could accumulate and cause problems in people. "These ...
chemicals, representing a third of organic chemicals in commercial use, constitute an unidentified class of potentially
bio-accumulative substances that require regulatory assessment to prevent possible ecosystem and human-health
When faced with extinction, butterflies on two South Pacific islands quickly developed
genetic defenses that helped them fight back, a team of international researchers said on Tuesday. They said the
butterflies' tale is the fastest example of natural selection observed to date and shows evolution can happen quickly
when the stakes are high. In 2001, male Hypolimnas bolina butterflies on the Samoan islands of Savaii and Upolu were
extremely rare. Just 1 percent of these butterflies - known commonly as Blue Moon or Great Eggfly - were male. They were
under attack by the Wolbachia bacteria, a parasite passed down through the female that kills off male butterflies before
they can hatch. Click here
Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950
to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists
estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about
one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Click
Environmental sustainability is already very difficult to achieve with today’s 6.6 billion
people and average economic output of $8,000 per person. By 2050 the earth could be home to more than nine billion
people with an average output of $20,000 or more. Many environmentalists take it for granted that richer countries will
have to cut their consumption sharply to stave off ecological disaster. There is another approach. Global public
policies and market institutions can promote new technologies that raise living standards yet reduce human impact on the
environment. A crucial group of such technologies is aquaculture, the farming of marine animals, which can support
growing human consumption of fish and other aquatic species while relieving intense pressures on ocean ecosystems.
The nation's top public health official on Saturday urged veterinarians to work more closely with
human-health researchers to curb contagious diseases. "Thirteen out of the last 14 new infectious diseases that have
affected people have arisen from animals," said Dr. Julie Gerberding, director of the Atlanta-based federal Centers for
Disease Control and Prevention. "We need a health system that can do fast science, fast detection ... fast and effective
communication, and a very, very important piece of this fast system is the alert veterinarian," she told the American
Veterinary Medical Association's annual convention here. Because animals share our food and water supply and have
greater contact with the elements, their sicknesses can provide an early alert to environmental problems, human disease
- and even bioterrorist attacks. Click
