Red tide
“Red tide” is a common name for a phenomenon known as an algal bloom, an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column, or “bloom”. These algae, more specifically phytoplankton, are microscopic, single-celled protists, plant-like organisms that can form dense, visible patches near the water’s surface. Certain species of phytoplankton contain photosynthetic pigments that vary in color from green to brown to red, and when the algae are present in high concentrations, the water appears to be discolored or murky, varying in color from white to almost black.

Man is destructive and disrespectful of nature; just sad that earth is fighting back the environment polluted and now only a few care. This is GODS earth HE allowed us also along with nature to inhabit and take care of it not destroy its beauty. Who knows why Red Tide occurs. Could be polluted waste by man.
