Jack Johnson (1878-1946), an African American boxer, was convicted of violating the Mann Act under suspiciously racist circumstances; now his family is seeking a pardon. I wish them the best, which is more than I can say for modern-day Jack Johnson, who should definitely not be pardoned for the craptastic music he produces. The catalytic converter that helps reduce my car’s emissions is indirectly tied to a rise in global levels of osmium. Also at Mother Jones this week, a recycling forum. Finally, having been regularly asked at Safeway to round up my bill to the nearest dollar in support of Muscular Cancer Shelter charity (it does all run together after a few trips), I sympathize with the question of what to do.
