There were two stories in Time Magazine that caught my attention last week.  One is about living longer and the other is about dying, but they have one key thing in common: reducing our air pollution.

In the first story, “Want to Live Longer? Cut the Pollution”, they cite a recent study in the New England Journal of Medicine.  The study details increased life spans for people who live in areas where pollution has been curbed.  Now this should not come as a surprise to anyone, but it is reassuring to see statistics to back it up.

Color on Dead TreesIn the second story, “Study: U.S. Trees Dying at Alarming Rate”, they look at the findings of a thirty-year study published in the journal Science.  The study finds that the death rate of trees in the western U.S. has more than doubled in the last few decades.  These are trees of all sizes and types in healthy, well-established forests.

We have already lost millions of tress to beetle infestations, but these are apparently healthy trees without evidence of infestation that have been weakened by global warming.  The real irony is that trees soak up large quantities of carbon dioxide and are critically important in slowing climate change.  So these trees will not be around to help clean the air and their dying actually releases carbon dioxide back into the air as a kind of global warming double whammy.

As temperatures slowly rise, this problem will worsen since the summer season will be longer which causes trees to be stressed and vulnerable to drought conditions.  More trees dying will have a direct effect on our air quality and ultimately our own longevity.

Aggressively reducing our auto emissions is a huge step in slowing the current rate of climate change.  Pay4Rides would help trees live longer, which improves the health of the planet and the air we breathe.  Now aren’t those a couple of great reasons to share rides?

Today President Obama endorsed efforts to allow states adopt rules for stricter emission standards.  In a USA Today story, Obama pushing stronger fuel-efficiency standard, they detail many of the reasons behind this initiative.It's the economy, stupid!

This may seem like bad news for the automakers, but they know these changes are necessary.  We need to focus on lessening our dependence on foreign oil for our own national security.  In a Wall Street Journal story, they make some excellent points:

President Obama again linked his energy agenda to the economy, the environment, and national security. Spending hundreds of billions of dollars on foreign oil helps finance terrorism, subjects Americans to volatile gasoline prices, and courts the “irreversible catastrophe” of climate change. “These are the facts,” he said.

This won’t happen over night, but it is a very good first step.  We need to aggressively curb our greenhouse gas emissions and slow global warming.  California has been ahead of the curve on this issue and it is about time the rest of the country caught up.

Higher gas mileage and lower emissions, sounds pretty obvious, doesn’t it?

Car & Passenger Vehicle Facts - lots of cars cost lots of money

The average American spends an hour and half in the car every day.  There are 300 million people in the U.S. and over 230 million registered vehicles.

Burning a gallon of gasoline produces 20 pounds of carbon dioxide, which contains 5 pounds of pure carbon.  So an average car that travels just 1,000 miles a month at an above average 25 miles per gallon would burn 40 gallons of gasoline and produce 800 pounds of carbon dioxide.  Just think about those numbers per car per month and multiply by 230 million.

IMG_6096In 2004, U.S. cars and light trucks traveled a combined 2.7 trillion miles. According to AAA, owning and operating a vehicle costs an average of $9,531 each year.  These costs include the type of vehicle, insurance, maintenance, tolls, parking fees and gasoline.

Wouldn’t you like to reduce those costs and drastically cut our emissions?
