We are told that we must decrease the so named ‘greenhouse gasses' by two degrees Celsius, or we are doomed. That is, all hell will break loose.
This mythical Holy Grail, once secured, will presumably be kept in check by some canute-like body, lamely ordering so.
Well, before these wondrous happenings are tackled, let's tear our eyes from the stars and take note of what's happening down here, on Mother Earth.
I commend your readers to Google up ‘The Worlds 10 Greatest Coal Producers'. If they strike the right reference, there are vivid pictures of vast tracts of land devoted to gigantic open cast coal mining. The method of extraction is easy, the product cheap and our world leaders are kidding themselves - and us - if they think that the producers will take a blind bit of notice of what anyone says.
However, the real harm these activities create, at the point of production, is terrible conditions for the workers and residents in the surrounding areas, with the choking, gritty pall constantly present, often wind-blown further afield. The casualties are real, now, before a single lump coal is converted into a ‘greenhouse gas'. Collateral damage, eh!
