Apparently, something nastier is afoot in California. California makes me think of abundant produce, like this from a friend's Facebook page, taken in February 2015.
However, this article on the California's dairy farms, which produce 20% of the US's dairy products, almost made me glad to be in Baltimore. Huge amounts of toxic particulate matter in the air shorten people's lives, and the impact on global warming is considerable. Ammonia, volatile organic compounds, and pressure on Latin American forests are other toxic byproducts of the expanding industry.
