Pollution is killing more than AIDS in Sao Paulo, says a Sao Paulo University report Air Pollution Lab.

According to the study, some nine people die each day because of pollution - which makes it some 3,500 a year. Less than half of that number of people, 1,624, die each year as a result of AIDS and traffic combined.

Sao Paulo will spend $1.5 billion on pollution-caused diseases, caused mainly by the six million cars in the city. Is it just me or that sounds like, if the cars don’t kill you in traffic, they will kill you with what comes out the back?

Nearly two-thirds of the air pollution is caused by 10% of the total vehicles, the ones that run on diesel fuel. Statistics say that there are about 150 lives lost each year due to sulfur releases from diesel-fueled vehicles and 232 deaths caused by AIDS.

Sao Paulo will adopt a “clean diesel” in 2009 hoping to reduce pollution by at least 5%. Seriously time for the “B” in Bric to clean up its act. - via Xinhuanet

It’s not the extinct white dolphin or something you might see at one of those incredible hotspots for whale watching, it’s the world’s largest shark, the whale shark. Researchers down under, that’s down under (Australia) and down under (underwater) attached devices for observation to eight sharks 8 meters (26′) long off Ningaloo. The devices which are designed to release from the sharks on command, track every move the giant fish makes over several hours.

The whale shark dives like a hawk, then soars like an eagle, using momentum and gravity to conserve energy. Momentum and gravity for conservation of energy? Is there something we landlubbers can learn here because to be honest the whale shark is as big as a bus!

The study was done under pretenses of protecting the whale sharks against whom or who? People who might stick devices to them maybe?

The devices are supposed to reveal where the sharks feed and breed so that we humans can know where and when to leave them alone. How about we just leave them alone. But, then if we aren’t careful, hunters will find them. And if the hunters don’t get them, pollution might.

So, do we study animals or should we leave them alone? What do you think?
