Fertilize in Kentucky, Cause a Red Tide?

Let me tell you a story about nitrogen. A farmer in western Kentucky applies nitrogen-based fertilizer to his crops. It rains. The rain carries run-off from his fields into a little stream nearby.

The vault, located in Norway and funded by the Norwegian government, is the world’s insurance policy on a host of threats that could destroy important crops, from global warming and war, to natural disasters like drought, flood and wildfire. The media have nicknamed it the “doomsday… Continue reading 'Doomsday' Seed Bank Opens In The Arctic
