Norman Borlaug, the unassuming Protestant agriculture researcher who saw it as his mission to feed the world. And even Slate called him the man who fed a billion people, because his dwarf grain varieties tripled food yield.
But no one will mention his faith as the reason he spent a lifetime trying to ensure we could feed everyone, much less proving environmentalist doom and gloom wrong.
It takes an atheist/communist like Stalin to crush a breadbasket (like Ukraine) into genocidal famine. It take a free Christian like Borlaug to open the door for plenty worldwide.
