What causes red tide?
Red tide is a natural phenomenon not caused by human beings. When temperature, salinity, and nutrients reach certain levels, a massive increase in Karenia brevis algae occurs. No one knows the exact combination of factors that causes red tide, but some experts believe high temperatures combined with a lack of wind and rainfall are usually at the root of red tide blooms. There are no known ways that humans can control it, but many scientists around the world are studying red tide at present. It’s important to remember that red tide has happened before and the Texas marine environment has always recovered.
