Red Tide Red Tide is an algae bloom that releases toxins into the ocean and releases horrible odors that can leave you with breathing problems such as horrible coughing fits, mild coughing or asthma in the worst cases . Algae blooms release toxins when they are in a highly concentrated state in the ocean that shellfish absorb but do not die. Instead they concentrate it all in their body in a small space and if a human eats the shellfish they have a huge chance of dying from the toxin. Algae bloom also affects fish because fish cannot absorb toxins and survive like shellfish, and due to toxins, there is a huge amount of fish that are killed by toxins and their lifeless bodies float up to the beach and if a bird tries to eat it it can even die due to poisoning. Red tides can occur due to human actions from agricultural runoff. Agricultural runoff can help form red tides because they are full of nitrates that will grow phytoplankton. Phytoplankton are single-celled, plant-like organisms that can form dense, visible blobs near the surface of the water. And when they are in an area of ​​high concentration they can produce toxins that can paralyze. They can also change color from brown to green to red. Another way red tides can occur due to humans is global warming (which humans have increased dramatically since 1970). Global warming has increased sea level temperatures which in turn will increase the number of phytoplankton and in turn can increase red tide. Red tide cannot only occur due to human actions but can also occur due to natural phenomena. For example, desert winds carry iron-rich sand into bodies of water that...... middle of paper ...... the presence of red tide is that in January 2013 there was a bloom of red tide on Sarasota beach, fortunately there was no one killed except fish and some people had breathing problems. To conclude, red tide is formed by the concentration of phytoplankton in an area. The bloom can kill you or cause respiratory problems if you eat the affected fish or stay in the area for a long time. Red tide can occur both naturally and artificially. It can form humans due to global warming (which is caused by air pollution). Agricultural pollution (which happens when fertilized soil ends up in water), and of course from desert, El Nino and desert sand events. To decrease the frequency or try to stop it people need to pollute less to decrease the frequency and also report any signs of red tide because if you do that the authorities will come to secure the area.
