As a result of climate change, water temperature is increasing throughout the United States. This increase accelerates the spread of toxic algae, which is becoming more frequent in states like Utah and Ohio. In Ohio, a 2014 algae bloom caused authorities to warn residents to avoid drinking tap water, suspending the principal water source for over 400,000 people. High doses of the algae’s toxins can cause liver damage and provoke an attack on the nervous system. Researchers also predict that long-term exposure to low levels of this toxin is potentially linked to liver cancer and neurodegenerative diseases.
