Interesting new column by Jonah Goldberg: "A rolling 'dead zone' off the Gulf of Mexico is killing sea life and destroying livelihoods. Recent estimates put the blob at nearly the size of New Jersey. Alas, I'm not talking about the Deepwater Horizon oil spill. ... I'm talking about the dead zone largely caused by fertilizer runoff from American farms along the Mississippi and Atchafalaya river basins."
