“Yellow Dust”, the dust plumes flown to Japan from Eurasia Continent in spring causing haze and pollution is received unplesantly, but overviewing from satellites reveals another surprising fact about this climatic event.

Dust from west coast of Africa travels 5,000km over the Atlantic Ocean to reach the Amazon rainforests of South America (5,000km is the approximate distance from New York, U.S. to Dublin, Ireland).

According to NASA, the Saharan dusts contain rock minerals such as phosphorous, an essential nutrient for plant proteins and growth, and is thought to provide nutrients for Amazon soils. Scientists point out the possibility of relationship between the growth of the vast Amazon rainforests and the Saharan sands.

Looking at things from one step back on a larger scale may give a valuable, new finding about the nature which may seem troublesome to humans on a smaller scale.
