As discussed in the last post, agriculture runoff is a huge problem. Nutrients are running off the land and into our oceans.Today in a recent article from Scientific America, the idea was batted around to take up ocean nutrients with kelp then turn it into fertilizers. These fertilizers could then be used again on land to replenish the nutrients lost. Not only would this help close the nutrient loop, but also take excess carbon out of the oceans.
This is just another example how seaweeds can help reverse negative anthropogenic impacts to our oceans.
