I agree ! However the climate in Canada is radically different and far colder than here in the UK! That doesn't justify the application of salt on roads worldwide but the problem and the solution doesn't rest with us. Our weather is benign when compared to most northern hemisphere countries like the USA, Canada, Russia , Japan, Korea, China, Mongolia, Sweden, Norway, Finland, Iceland, Greenland, Turkey, Bulgaria, Switzerland , Austria, Latvia, Estonia, Lithuania and probably loads more!
We struggle and moan when we get a couple of inches of snow once in a blue moon! Most countries with severe winters insist on winter tyres for all vehicles from October through April! Our climate just doesn't justify that? My wife's Car has all season tyres which are great in snow but not as good as winter tyres! Snow chains are utterly impractical in the UK!
A world wide effort is required !
