*Today, most of civilization exists within congested smoggy cities. Fossil fuel air pollution, including filthy diesel fumes loaded with fine particles of nitric oxide and nitrogen oxide, are quickly crippling, dogs, bees and man.
About two decades ago in Mexico City, my colleagues began investigating an increasing number of howling frightened dogs that grew disoriented and incapable of recognizing their owners.
They examined the dog’s brains and found them coated with the protein amyloid beta, or, plaque, linked with Alzheimer’s disease. The dogs, they concluded after further experiments, had lost their minds from breathing the exhaust fumes of fossil fuel combustion.
