So, it seems there are 4th grade curriculum materials developed by Scholastic with funding from the coal industry, which touts the use of coal but without noting

the negative effects of mining and burning coal: the removal of Appalachian mountaintops; the release of sulfur dioxide, mercury and arsenic; the toxic wastes; the mining accidents; the lung disease.

Student advocacy groups are not happy. The coal industry got what it paid for, but now it has a black eye, and its (and Scholastic’s) PR people are working overtime to address these matters.

It seems to me that we don’t need to spend public money on classroom materials that has been developed without full attention to all the issues, not the least of which are environmental and health effects.
