As if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.
Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.
Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brain’s cortex within 30 minutes, which continued even after they left the room.

As a lifelong Catholic and former Catholic priest, I often find myself wishing that the Church would stick to what it knows best: the Sacraments. I wish the Pope would declare a 10-year moratorium on anyone with any authority in the Church saying anything at all about sexuality.
But sometimes the Vatican gets it right.

George W. Bush has definitely been a polarizing personality in his two terms as leader of the United States of America. From the beginning and his War on Iraq he has seemingly attempted to paint himself as nothing more than a moronic menace. Of late, Bush has turned his sights on becoming the world’s greatest environmental foe.
Some may call my words harsh. Others will praise them. They are however, nothing more than my personal opinion about him.
However his actions against the environment are both unquestionable and unconscionable.
A recent Reuters article stated that ‘In cases this week dealing with polar bears, ozone smog and environmental research, groups that monitor these decisions faulted the Bush administration for slighting science in favor of politics.’ I feel that, in looking at the past few months, this statement fails to explain just how Bush has thrown his weight around.

The life of someone looking to support the environment is a tough one, especially with news like this. The Kyoto Protocol was supposed to be Earth’s savior; or at least a benefit concert. But new information provided by the Chinese government has shown that by 2010 Chinese greenhouse gas emissions will have managed to eclipse the reductions achieved by all the countries underneath the Kyoto protocol.

Ag industry lobbyists and lawmakers from agricultural states have pressured the Environmental Protection Agency to drop requirements that factory farms report their emissions of toxic gases — even though the EPA’s findings show the gases pose a health threat.
In a head-spinning move, the EPA complied, citing that the reports are not used by local emergency workers and are thus, unnecessary. Unnecessary to whom? It seems valid that the acknowledged threat to residents living and working nearby would be important information.
Unless, of course, they could be used in a lawsuit against you, which has happened with several industrial farms since 1980 when the EPA was first required to document the emissions of ammonia and hydrogen sulfide. These reports are one of the few tools rural communities have for holding large livestock operations accountable for the pollution they produce.

And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it. - Genesis 2:15
Jim Lackey is not amused that the media - new media bloggers included - keep churning out misleading headlines on what the good old Archbishop Gianfranco Girotti actually said about sinning environmentally.
If you’re wondering who the hell the Lackey fellow is, Jim Lackey is the general news editor of the Catholic News Service and he says there is nothing new about environmental blighting as a sin. He says editors are just having fun and are committing another sin in the process - adulteration of the original ingredient! But the CNS website itself has “NEW SINS” as the sub headline to the big story. Perhaps he means it’s an old sin with a new definition?

For centuries, Northern and Southern Europe have been divided by the Alps, a natural mountain barrier which neatly dissects the central part of the continent, running from Austria, across Switzerland and into France. However, all is set to change with the construction of the world’s longest tunnel, allowing direct travel through the alps for the first time since dinosaurs roamed the earth.
In modern times, trade between North and South has seen an increasing volume of trucks making the long, slow journey through narrow valleys, high passes, and long tunnels, many of which twist and spiral their way through the rugged mountain terrain. At the beginning of school holidays, tailbacks at the entrance to the 15 mile Gotthard road tunnel can reach 30 kilometres as droves of Northern Europeans migrate South for the food, wine and sunshine of Italy.
Concerned by the consequent increase in pollution (amplified as the narrow valleys trap particulate emissions from cars and trucks, which threatens the balance of delicate alpine eco-systems), the Swiss voted in 1994 to limit trans-alpine freight transport to 650,000 trucks per year. Achieving this will involve a massive engineering project, with 2,000 people working on the new Gotthard Base Tunnel, 24 hours a day, 365 days a year.

The car is an enduring symbol of personal freedom. Small wonder then, that in many countries attempts to place restrictions around car usage are fiercely resisted.
The City of London has faced stern opposition over its new congestion charges (even being threatened with legal action from Porsche), the Germans refuse to bow to pressure from environmental groups to put speed limits on their unrestricted autobahns, speed cameras are branded as a universal menace and Detroit automakers have been vigorously opposed to a national fleet average fuel consumption figure of 35mpg.
The super environmentally conscious nation of Switzerland puts a healthy environment above the freedom of the highway. This week, motorists in the Italian thinking region of Switzerland may drive no faster than 80kmh to compensate for high levels of air pollution in the region.

"It looks like the days of skiing on South facing slopes are numbered" remarked the skier to his companion over an apres ski beer in the Swiss resort of Toggenburg. As the two observed the mixture of mud, grass and snow on the slower ski runs on a February afternoon, they murmured about the regretful advance of climate change, the impacts of which were occurring before their very eyes.
Sitting at the table opposite, and having previously wiped mud from my skis for the first time ever, I observed the pair finish their drinks as they continued to discuss the impending catastrophe, before tottering across the car park and jumping in to a large BMW SUV, apparently oblivious to their own part in the play. Similar scenes are replayed daily the world over. Many people agree that human-kind is having a negative impact on our environment, but few are taking direct action. - more on this later.
Most of Earth might be covered with water, but the large population of bipedal animals that crowd the planet’s land masses is doing its best to leave its imprint on the oceans as well.
A new study from the National Oceanic and Atmospheric Administration (NOAA) finds that humans have had a heavy impact on more than 40 percent of the world’s oceans. That’s an […]
