In This Mass Extinction, the Enemy Is Us

The New Yorker magazine quotes Fisher professor of natural history Andrew Knoll on the current mass extinction. The enemy is us.

A human fibroblast—part of the body’s connective tissue—sits on a bed of vertical nanowires in this image from a scanning electron microscope. Hongkun Park and his colleagues hope that the nanowires, which penetrate the cell without harming it, can be a way to introduce genes into cells without the use of an engineered virus or invasive delivery method. One application could be adding a set of genes to fibroblasts that “reprogram” them to act like stem cells.

Particulate matter that is 2.5 microns or less in diameter (PM2.5), the kind emitted from smokestacks and tailpipes, is known to be especially harmful. Reductions in such pollution lead to increased life expectancy. In Boston between 1980 and 2000, for example, as PM2.5 concentrations dropped from 18 to 11 micrograms per cubic meter, local average life expectancy climbed four years. Of that increase, four-tenths of a year—or 10 percent of the total gain—was attributable to improved air quality.

Clean Air, Longer Life

Controls on fine particle pollution extended average lifespan in the United States by five months between 1980 and 2000.
