Louisville is worried about ethanol pollution.
Ethanol, a fuel that's backed by state and federal governments and viewed as a boon to corn farmers in the Midwest and South, may make it harder to breathe in Louisville this summer.
While governors in more than 25 states, including Kentucky and Indiana, tout it as a way to make gasoline burn cleaner, there's new evidence ethanol can worsen some types of pollution linked to damaging health effects — namely ozone and fine particles.
And that could make it harder for cities like Louisville, where it already is being used, to meet air standards.
This is my problem with environmentalism. I want to protect the environment, as do most people, but many of us just get tired of people jumping to conclusions about the causes, effects, and solutions for environmental problems.
