Al Gore, you had better get rid of your lawnmower

What has Al Gore got to do with lawnmowers? A lot. I recently discovered, to my horror, that a typical gas powered lawnmower produces as much pollution in 7 hours of operation as a modern car does in a 100,000 miles of driving! Another way of looking at this is that the two-stroke gasoline lawnmower that is ubiquitous in the suburbs of North America, pollutes (PM, NOx, etc) as much in one hour as 40 late model cars running for the same amount of time!
Why? Because the off-road engines found on lawnmowers, leaf blowers, tillers, as well as snow blowers, snowmobiles and dirt bikes don’t have to have catalytic converters. These handy devices reduce gasoline emissions by about 90%, and are mandatory on cars and trucks.
