Salt placed on roads to melt ice is an environmental disaster. But a new innovation is the residue from beets , producing sugar, and the salty water from making cheese. The industry had no use for this product so sold all cities to use it for melting ice. Now millions of tons are used on Winter roads all across the NA. It is an environmental disaster of huge proportions probably as bad if not worse than the use of DDT. The run off affects the food supply of beneficial insects. In my area the earthworms, snails, Colorado Potato beetles, butterflies and bees have virtually disappeared. Environment authorities are sound asleep at the switch. I have contacted the city of Brantford and the Ontario environmental authorities and got no where. Almost all cities are on the bandwagon using the beet and whey juice. Time to awaken the authorities up.
