Red tides are caused by algae, which are tiny, microscopic organisms that grow in the water. In fact, the water changes color in a red tide because the population of algae living in the water becomes so dense. Red tides have been around since long before humans.

A “red tide” is a common term used for a harmful algal bloom. This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe.

Current Conditions. A patchy bloom of the red tide organism, Karenia brevis, persists on the Florida Gulf Coast.

Red tides are naturally occurring, but there is ample evidence that shows nutrient pollution can fuel blooms, making them larger and longer lasting….Make your yard more Ocean Friendly.

1. Go organic.
2. Apply mulch and compost to build healthy living soil instead.
3. Plant native and climate-appropriate plants.

Dinoflagellate ‘blooms’ (cell population explosions) can cause discoloration of the water (known as red tides) which can have harmful effects on the surrounding sea life and aquaculture. Some dinoflagellates species produce toxins that can kill both finfish and shrimp and indirectly to other consumers.

Florida’s lakes, rivers, springs and estuaries routinely have some of the nation’s worst algae blooms. Along with endangering public health and wildlife, the blooms cost local economies hundreds of millions of dollars.

The most common and widespread contaminants in Florida are bacteria, nitrates and lead. Other chemicals like ethylene dibromide (EDB), tetrachlorethylene (PCE) and temik have also been found in isolated areas. Contaminated drinking water can cause a number of diseases, and is sometimes fatal to vulnerable people.

Emergency crews in Florida have been working to prevent a “catastrophic” flood after a leak was found in a large reservoir of toxic wastewater. Officials said the 77-acre (31-hectare) reservoir holds millions of gallons of water containing phosphorus and nitrogen from an old phosphate plant.

Florida’s regional water conflicts stem primarily from the fact that the majority of the fresh water supply is found in the rural north, while the bulk of the population, and therefore water consumption, resides in the south.

The city of Tallahassee’s drinking water has been declared the best in the state of Florida.

But the water crisis is not restricted to Florida alone—or even California, Texas, and Arizona. It is part of a wider national water crisis across that United States. A government-backed study predicts serious water shortages in nearly half of America’s water basins in around 50 years—sooner in some places.

Florida’s high point is 345 feet above sea level, the lowest of all fifty states. Thus it will never go completely underwater, even if all the ice sheets and glaciers on the planet melt, since a total meltdown of all the ice sheets glaciers would raise sea level 212 feet (65 meters).

At any rate, it could even be as early as 2050 when much of the Florida coastline would be underwater, depending on what the results of newer data might say. Flooding would affect Miami, Orlando, Tampa Bay and any other major center touching saltwater.

According to scientists with the California Geological Survey, low-lying beach towns such as Santa Monica, Malibu, Venice, Marina del Rey, Redondo Beach, Long Beach, Seal Beach and Newport Beach are all vulnerable to a catastrophic tsunami.

CoreLogic, a business analysis service, estimated a Southern San Andreas fault rupture will cause 3.5 million homes to be at risk with $289 billion in reconstruction value. Water, electricity and gas lines cross the San Andreas fault in Los Angeles. They break during the quake and remain unfixed for months.

The world in 2050 is more hostile and less fertile, more crowded and less diverse. Compared with 2019, there are more trees, but fewer forests, more concrete, but less stability. The rich have retreated into air-conditioned sanctums behind ever higher walls.
