Unlike alcohol, we have a positive social image associated with cell-phone use, even when in the car — it’s the very image of viral multi-tasking. We need to call home to find out if there’s milk in the fridge (somehow we got by without the ability when I first learned to drive). But that positive image is an illusion, and it may be just one factor that helps explain the stubbornly high crash and fatality levels in this country. I can hear you say, but I drive all the time on my phone. Most drunks make it home at night too, through sheer dumb luck, but think of all the death and damage done by those who don’t. Laws will be hard to enforce on this; what we really need is a strong social norm that says it’s just not a good idea to drive and talk — and hands-free offers no cognitive benefit over a hand-held cell-phone.

Despite advances in traffic and car safety, driving remains the most perilous thing most of us do each day.  And though the average American is more likely to be killed with a car than with a gun, on the whole, drivers have little anxiety about driving.  Hubris is just one of several reasons why. The propensity of drivers to overestimate their ability has been well documented, especially by Tom Vanderbilt. In Traffic, he explains how the false sense of control and ease driving provides, along with humans’ inability to self-assess, allows most drivers to rate themselves “above average.” The dangerous outcome is a “narcissism” that encourages aggressive driving.

What happens to most of us, in most driving conditions, is that we’re losing some of the key attributes that facilitate human cooperation and, in a larger sense, society. Eye contact, for example, has been shown in any number of experiments to increase the chance of gaining cooperation — that’s why when drivers give you what was called on Seinfeld the “stare-ahead,” your chances that they’ll let you merge in ahead of them are greatly reduced. Then there’s the anonymity in traffic — there’s no one to spread rumors or gossip about you about how bad your behavior was — not to mention the lack of consequences for acting like an idiot. It’s all strikingly similar to the way we act on the internet, in what’s called the “online disinhibition effect.”

Vehicle emissions can affect the environment in several ways. Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. (See Reference 2, page 13) Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals. (See Reference 5) Nitrogen oxides and sulfur oxides are major contributors to acid rain, which changes the pH of waterways and soils and can harm the organisms that rely on these resources.

Long-term stress increases the risk of cardiovascular disease, he says. Research on the precise level of cardiovascular risk is limited, but recent data doesn't paint a flattering picture for the vehicular commuter. A 2012 study in the American Journal of Preventive Medicine found that the farther people commute by vehicle, the higher their blood pressure and body mass index is likely to be. Also, the farther the commute, the less physical activity the person was likely to get.

The BHFNC review suggests that sedentary behaviour is associated with an increased risk of Type 2 diabetes, cardiovascular disease and death from all causes in adults. And, although findings are somewhat inconsistent, this type of behaviour may also increase an adult's risk of certain types of cancer. WCRF/AICR's Expert Report concluded that the evidence that sedentary living causes weight gain, being overweight and obesity is convincing.

Cars, once again, are killing us. They're killing us in crashes and accidents, yes, and they're encouraging us to grow obese and then killing us a little more slowly. But, more than ever before, they're killing us with their pollution.  Particulate air pollution, along with obesity, are now the two fastest-growing causes of death in the world, according to a new study published in the Lancet.

About 19.64 pounds of carbon dioxide (CO2) are produced from burning a gallon of gasoline that does not contain ethanol. Most of the retail gasoline now sold in the U.S. contains about 10% ethanol by volume.  Under international agreement, CO2 from ethanol and other biofuels are not counted at the tailpipe, so burning a gallon of gasoline with 10% ethanol produces about 17.68 pounds of CO2.

Most experts agree that threatened egotism is also associated with murder, rape, as well as gang activity. Making the jump to aggressive driving involves the very same ego-centric behavior. So in this context, a narcissistic driver may perceive another driver’s action as a personal threat to their inflated ego leading to retaliation, which is often manifested as aggressive driving!

Actually narcissism as a cultural force may contribute to the sense out there that driving behavior has gotten progressively worse. This tracks with increases in self-reported narcissistic behavior in psychological tests. More people these days are likely to say “yes” to questions like “if I ruled the world, it would be a better place,” and more people seem to be driving in that spirit.

Do the thing several times a day, and it becomes banal.  Though how much and how fast we drive are key determinants of crash risk, driving everywhere, no matter how short the trip, and speeding, no matter how little time is saved, have been normalized. This normalization is what makes crashes, when they happen, so difficult to process.

Burning 1 gallon of gasoline creates 20 pounds of equivalent CO2. Fossil fuel-powered transportation pumps more than 1.7 billion tons of carbon equivalent emissions into the air annually.

Using one gallon of gasoline in your car produces about 20 pounds of carbon dioxide emissions directly, or 26 pounds if you account for upstream processing of the fuel.

It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. When gasoline burns, the carbon and hydrogen separate. The hydrogen combines with oxygen to form water (H2O), and carbon combines with oxygen to form carbon dioxide (CO2).

The primary greenhouse gas responsible for global warming is carbon dioxide. The U.S. is responsible for 19.91% of the carbon dioxide emissions worldwide.

The combustion of fossil fuels. such as gasoline and diesel to transport people and goods is the second largest source of CO2 emissions, accounting for about 31% of total U.S. CO2 emissions and 26% of total U.S. greenhouse gas emissions in 2010.

To arrest man-made global warming, the world needs to stop the atmospheric stock of greenhouse gases from increasing. This requires emissions to be reduced until they balance with the rate of natural removal from the atmosphere.

THE WORLD is changing; opinions are changing, economies are changing, values are changing and the environment is changing.The environment is arguably the most important thing that is drastically transforming. This global warming, as we know it, is being caused by the burning of fossil fuels — emitting CO2 and other greenhouse gasses into the atmosphere. These fuels are burned in cars, in our homes and first and foremost in power generating stations. One of the primary fuels burned in power stations is coal and lets get one thing straight from the start: burning coal is not clean.

Carbon dioxide takes 100 years to disperse in the atmosphere. Even if emissions are stopped today, we will still feel the effects for years to come.

Here's what we know: an overwhelming majority of scientists tell us that the Earth's climate is heating largely due to rising greenhouse gas emissions, which, in turn, is driving more extreme weather and climate events. The underlying changes -- warmer oceans, more intense precipitation events, and rising sea levels -- are significant contributors to storms like Sandy. Around the world, we're seeing heavier rainfall and record-breaking high temperatures, and many areas are experiencing more severe droughts and more wildfires. These patterns are precisely what climate scientists have said we should expect in a warming world. Further, these extreme weather and climate events are taking a serious toll as they disrupt people's lives and our economy.

We just assume when we turn on the tap, the water will be there, and that the water system buried in the ground is doing fine. Both assumptions are out of date. Population growth, economic development (which changes dramatically how much water people want and use), and climate change are all putting pressure on water supplies — not just in places like Las Vegas or California, but in Atlanta, in Florida, in Spain, across China.

Average temperatures in the Arctic region are rising twice as fast as they are elsewhere in the world. Arctic ice is getting thinner, melting and rupturing. For example, the largest single block of ice in the Arctic, the Ward Hunt Ice Shelf, had been around for 3,000 years before it started cracking in 2000. Within two years it had split all the way through and is now breaking into pieces.

"The general consensus is that if you power an electric vehicle from coal, the net carbon emissions are about the same as a gasoline vehicle," says Paul Denholm, senior analyst at the National Renewable Energy Laboratory in Golden, Colo. "But that's the worst-case scenario; anything that is a cleaner source is an improvement."
