Are farmers, ranchers and truckers the new ‘canaries in the coal mine’?

Frida Ghitis: Are farmers, ranchers and truckers the new canaries in the coal mine’? Ghitis says there are few groups who work harder, have more common sense or offer up more pragmatic solutions than farmers, truckers and truck drivers.

She says some members of these groups have been waving “warning flags” of dangers to society’s functioning, but world leaders have turned a blind eye to their pleas, or worse, vilifying those who speak out about problematic government policies.

Ghitis writes: Politicians and activists often ignore such pragmatic advice.

Douglas MacKinnon: Maybe it's time to pause the politics and pontificating for a moment to listen to them, before it’s too late. They’re the real “experts” in my mind. So, maybe it”s time to stop the politics.
