‘Tis the season of farmers’ markets. Last week I moseyed on down to the Southampton (NY) farmers market and picked up some tasty, locally produced cheese that melted in my mouth with a delicious tang. But that local dairy farmer and others like him could become an endangered species if we continue on our current carbon-spewing energy path. Cows don’t produce much in very hot weather and scientists say that “heat stress and other factors could cause a decline in milk production of up to 20 percent or higher” in the Northeast under a business-as-usual (BAU) scenario. That’s a big deal: dairy is the largest agricultural sector in the region, producing some $3.6 billion dollars annually.
