I've heard of estrogen but not oestrogen. Does it come from ostriches? Why do you give your ostriches contraceptives? ;D I don't eat fish because all the fish in the world are full of mercury. I would only eat a farm raised fish and those are hard to find. If I didn't live in Arizona where water is scarce I would have my own fish farm and raise my own fish. La la la~ Er... LA la laaa~.... LA LA LAAAA!! Dang high notes.

www.outsideonline.com/news-from-the-field/Human-Waste-Melting-Out-From-McKinley.htmlHUMAN WASTE MELTING OUT FROM MCKINLEY Tons of human waste dumped into crevasses on Mt. McKinley's glaciers could surface in the next two decades, according to scientists from Alaska Pacific University. Glaciologist Mike Loso says that the estimated 65 tons of solid waste will work its way to the bottom of the glacier in the next 15 to 25 years. But while the droppings will still be full of illness-causing bacteria like fecal coliform and E. coli, it won't likely pose a threat to human health. "We could do the math and figure out how many kilograms of bear poop are out there and we'd come up with a huge number too," Loso said. Climbers on the peak are required to carry out waste in Clean Mountain Cans lower on the peak, but can dump it in crevasses higher on the mountain.

Shrinking leaves point to climate change

Wednesday, 4 July 2012 University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size.
The study, which is the first of its kind in the world, highlights that plant species are already responding to changes in climate. The results are published online today in the Royal Society journal Biology Letters.
Researchers analysed leaves from herbarium specimens of Narrow-leaf Hopbush (Dodonaea viscosa subsp. angustissima) dating from the 1880s to the present. The study focused on specimens from South Australia's Flinders Ranges.
The analysis revealed a 2mm decrease in leaf width (within a total range of 1-9mm) over 127 years across the region. Between 1950 and 2005, there has been a 1.2ÂșC increase in maximum temperatures in South Australia but little change in rainfall in the Flinders Ranges.
"Climate change is often discussed in terms of future impacts, but changes in temperature over recent decades have already been ecologically significant," says Dr Greg Guerin, a Postdoctoral Fellow with the University of Adelaide's School of Earth and Environmental Sciences and lead author of the study.
"Climate change is driving adaptive shifts within plant species and leaf shape has demonstrated adaptive significance in relation to climate.
"Our results indicate that leaf width is closely linked to maximum temperatures, and plants from warmer latitudes typically have narrower leaves.
"In the case of Narrow-leaf Hopbush, we can significantly link the changes in leaf width to changes in climate."
Dr Guerin says some Australian plant species have greater potential to respond to and cope with increasing temperatures than others. "It's important to understand how plants cope with changing climates, because species that are more adaptive to change may be good candidates for environmental restoration efforts.
"Other species in the region have less potential to adapt. These species may rely more heavily on migration - moving from location to location where the climate is favourable - but this can be problematic in a landscape fragmented by human activity," Dr Guerin says.
