Having no cars at all would do little, in time. All the cars in the world make
less than %10 of the worlds co2. I think the point of diminishing returns is
long past for cars. What's needed is work starting now on getting the co2 in
the air out. It's know how to drop the level to pre industrial times. But there
is no big money in it. Obama' science guy is looking into it. but no one in the
greens ever has. better to hate cars and fat people. better to keep saying the
same old things that have not done enough. it's believeded the seaes have about
100 years before all life in them dies. Then we will.
