Should we return to the age of horse & buggy?
Nah!
The horse and buggy age about to return?
First, there's the horse manure problem.
Second, growing oats for horses would rob starving people
of wheat or rice.
Third, horse buggies would be uncomfortably cold in the winter
up here in Alberta, and most of North America.
Then you would need horses for the military, and they would need kevlar armor
to protect them from bullets and shrapnel.
Nah!!!...Horses ain't the solution in place of our petroleum comsuming vehicles.
