(Never mind the fact that many Wisconsin highways are deserted for most of the day; see Hy 151 southwest of Madistan and Hy 26 south of Jefferson). But I digress.
The REAL objection to the RoadBuilders?
Concrete is the most widely used man-made material in existence. It is second only to water as the most-consumed resource on the planet.They kill baby seals, polar bears, and kittens!!!
But, while cement - the key ingredient in concrete - has shaped much of our built environment, it also has a massive carbon footprint.
Cement is the source of about 8% of the world's carbon dioxide (CO2) emissions, according to think tank Chatham House.
If the cement industry were a country, it would be the third largest emitter in the world - behind China and the US. It contributes more CO2 than aviation fuel (2.5%) and is not far behind the global agriculture business (12%).
