Suddenly the Sphinx collapses! Can this really happen or is this imagined? Believe it or not, this is can actually happen. If we stop pollution this will not happen.

Unfortunately, the rich silt that normally fertilized the dry Egyptian land settled in Lake Nasser after the building of the dam, forcing farmers to use one million tons of artificial fertilizer every year“ Artificial fertilizer can have devastating effects on the land. The website “https://www.scientificamerican.com/article/how-fertilizers-harm-earth/” states “A related issue is the poisoning of aquatic life. According to the U.S. Centers for Disease
