Red tide is a harmful algal bloom that causes discoloration of the water and can produce toxins that are harmful to humans and marine life. In recent years, red tide has become increasingly common and intense in the Gulf of Mexico, including in Naples, Florida. This article provides an overview of red tide, its causes and effects, and what you can do to stay safe if you're visiting or living in Naples.
Red tide is caused by a microscopic alga called Karenia brevis. This alga naturally occurs in the Gulf of Mexico, but when conditions are favorable, it can multiply rapidly and form blooms. Red tide blooms can last for weeks or even months, and can spread over hundreds of miles.
Red tide can have a number of negative impacts on human health and the environment. The toxins produced by Karenia brevis can cause respiratory irritation, eye irritation, and skin irritation. In severe cases, red tide can also lead to neurological problems and even death. Red tide can also harm marine life, causing fish kills and damage to coral reefs.
