Jevons paradox applied to leisure time

Weed by Bassett Creek pond
Isn't it odd that with all of our time saving devises we seemed to be the most rushed people ever?  Wikipedia states that Jevons paradox proposes that the technological progress that increases the efficiency with with a resource is used tends to increase (rather than decrease) the rate of consumption of that resource. It occurs to me an example of the Jevons paradox is how technology has increased our leisure time, yet seemingly we are living a less leisurely lifestyle than ever before.  Think of all the time saving innovations we have had over the past couple hundred years; telephones, automobiles, washing machines, airline travel, computers, microwave ovens, email and twitter.  Yet, who is more rushed and harried, people living in this century or those a couple of centuries back?  I can't imagine that riding a horse and buggy would have been nearly the same experience as cruising down a busy highway with a bluetooth phone in ear trying to get some work done or keep up with family members. How much different it is sitting down together as a family conversing over a home cooked meal versus popping in a microwave dinner in the microwave for oneself, while watching the news on television and texting a friend.

There is truth in that old saying,"the hurrier I go, the behinder I get". We're going mighty fast these days, and I don't think it is helping us to live a fuller, more satisfying life.  Paradoxically with all of our time saving devises we've become more like human doings and less like human beings.

Fuel efficiency alone is not the environmental solution

Toyota Prius
      In an interesting article by the Simplicity Institute, The Voluntary Simplicity Movement: A Multi-National Survey Analysis in Theoretical Context, I learned about the Jevons paradox.  Somewhat paradoxically, simply through making technology more efficient we actually end up using more resources. So for example with our recent purchase of a fuel efficient Prius, the natural tendency is to drive more, given we don't need to spend as much on the price of gas.  With more fuel efficient cars this then drives down the cost of fuel as demand decreases, and hence again, increases consumption, given the lower prices.
     I have to confess that I've felt less compelled to walk or bike to get groceries now have a car that is getting over 40 m.p.g.

Simply relying on advances in technology will not reduce our consumption of fuel and the related emissions of carbon dioxide and other pollutants. We still must have government intervention to help consumers reduce their demand.  This intervention could come in the form of green taxes, a cap and trade program or higher fuel taxes.  Ideally these taxes could then help to remediate the ecological damage caused by our fuel use.  
     There is growing interest in a "green tax" that would be on carbon emissions.  It has been estimated that the median incremental damage to our environment is $14 per ton of carbon, but some estimates go as high as $350 per ton. The average North American generates about 20 metric tons of carbon dioxide each year.  This compares to a global average of 4 tons.
     Unlike our household garbage, that we can clearly see and measure, it is difficult for most people to be aware of their carbon dioxide emissions. If we are indeed serious about our emissions, we need to start measuring them and tax accordingly.
