We’ve gotten so much great feedback on our June story “Running the Numbers” about Chris Jordan’s photographs — we’ve received dozens of letters from readers galvanized to help change the cycle of wastefulness in their communities. Check out this new post about Jordan on Ethicurean today.

Incense might do more than just smell good. In a study, to be published in the October issue of the journal Cancer, that involved more than 61,000 Singaporeans, incense burning nearly doubled the risk of upper respiratory cancers — whether subject smoked cigarettes or not. Although there was no evidence to suggest that incense burning increased the risk of lung cancer, the American Lung Association plans to add incense burning to the list of risk factors for the disease. But casual incense users don’t necessarily have to stub out that sandlewood: Only people who burn incense regularly and heavily are at risk. Casual use is probably harmless.
