The heat index shot up to 53 degrees Celsius in some provinces with significant impacts on vegetation and biodiversity. Lake eutrophication becomes an increasing threat due to the excessive anthropogenic nutrient input from fertilizers, aquaculture, pollution.

Therefore, the possibility of another factor was taken into consideration. A number of ponds on Cape Cod show signs of eutrophication. Plant nutrients accumulate in these ponds over periods of centuries, increased plant growth (including algae) form more bottom sediments, and gradu- ally the pond becomes shallow. The process starts slowly and after a certain time its speed increases. Presently we
