1700 tonnes of snow

In the Volvo winter brochure it is written: “Every year 1700 tons of snow fall on the earth” Isn’t that a bit less? Will it be more if we drive more V8? Or less? or does it mean better on the earth? Or does it only apply to Sweden? Still, it seems too little to me. 1 Kubik snow should weigh 30-60kg in powder snow, 200kg in cardboard snow. who can clarify it? doxc
