This cool video from NASA shows how dust is transferred across the Atlantic to the Amazon rainforest and helps nourish the plants growing there. For the first time scientists have measured the amount of dust and the amount of phosphorus in the dust. The later acts like a fertiliser and helps replenish the phosphorus the rainforest loses each year, around 22,000 tons. Amazing how something we perceive as being desolate like a desert actually has an important role in sustaining somewhere we see as teeming with life.
