PLANET IN PERIL

Environmental Health Perspectives Cattle graze in a field as gas flares from a pumping installation on the Eagle Ford Shale in Karnes County, Texas. The shale oil boom is going strong on a formation that stretches for about 500 kilomtres across south Texas, one of the most prolific oil patches in the U.S. Excess gas is burned off at oil pumping stations which dot the countryside. A Greenpeace photo. Several studies have examined the association between unconventional oil and gas development and adverse birth outcomes. But up to now, no study is known to have looked specifically at flaring—the controlled burning of natural gas at the well site to relieve pressure or dispose of waste gas.1 In a recent article in Environmental Health Perspectives, investigators report their findings on flaring and maternal and fetal outcomes.  Details here.

Using tools which included video taken by a robot submarine, a Canadian research team recently discovered an amazing array of plants and animals, living in the hear t of Milne, the very ice shelf which broke apart just this summer north of Ellesmere Island (above), losing almost half of its mass. Dr. Derek Mueller, Professor of Geography and Environment Science at Ottawa's Carleton University, is a team member who's worked in the area for decades. In an email to PinP, he can barely disguise his excitement over what they found. "There are really neat microbial mats (communities of micro-organisms including cyanobacteria, green algae, diatoms, heterotrophic bacteria, and viruses) that li

Close ties between the ruling elite and the coal industry have helped perpetuate South Africa’s dependence on the dirtiest fossil fuel for electricity. But now residents of the nation’s most coal-intensive region are suing to force the government to clean up choking air pollution. Story here.

by Larry Powell   A thick blanket of smoke again darkens skies over northern India. Every year, farmers light large numbers of small fires between September and December—after the monsoon season—to burn off rice stalks and straw leftover after harvest, a practice known as stubble or paddy burning. (A NASA satellite image.)  Details here. Smoke from burning stubble hovers over a small town in southwestern Manitoba, CA. Nov. 2020. A PinP photo. Canada is no stranger to the same practise. While "stubble-burning" in this country did not approach that of India's (at least not this year), numerous such fires were still common again this fall over the eastern prairies (See above) and in past years (below).

 By Larry Powell An adult female grizzly  (Ursus arctos). "BearID," as the program  is called,  captures a bear’s face in a  photo image,  rotates,  extracts and embeds it in order to classify the individual.   Facial recognition techniques have long been used to identify primates, including humans. But, up 'til now, there's really been no effective way of identifying wild species like the grizzly (brown) bear who, unlike the zebra or giraffe, lacks unique and consistent body markings.       In co-operation with two US software developers, four scientists from the University of Victoria bought their idea to reality. They tested their system on grizzlies at two locations - Knight Inlet, BC, and Katmai National Park, Alaska. After taking thousands of pictures, they were able to positively identify 132 individuals with almost eighty-four percent accuracy.  An adult female in another colour phase.
