Thank you for pointing out that Suffolk County's smog is a local symptom of a larger emissions problem, much of it off-Island -- and we, unfortunately, happen to be downwind ["Suffolk fails an air pollution test, again," News, April 30].

The lesson here is that our atmosphere is a shared resource. Emissions are bad not only for people's lungs but for our planet's temperature. Fossil fuel-burning power plants are spewing pollution, but they're not paying for the consequences.

To start curbing these emissions, we need legislation like what was passed in British Columbia in 2008. It makes polluters pay, and greenhouse gas emissions dropped 10 percent between 2008 and 2011. We should do the same.
