Cheap in the short run, costly in the long. Another way superstores are destroying the planet…this year’s severe outbreak of late blight fungus has been traced to tomatoes sold out of Wal-Mart, Lowe’s, Home Depot, and the like, all sourced from the same Alabama factory(farm). Late blight thrives in damp cool weather, so it’s been having a good ol' time on our coast this record-breaking cold wet summer. Bottom line: a really bad year for farmers and few tomatoes and potatoes for us.
For history fans, late blight is the fungus that caused the Irish famine... well, destroyed the spuds, anyway, since it was the Brits, who continued to export food from Ireland throughout, who caused the famine.
