Algal Doom: The Growing Threat of Harmful Algal Blooms

Algal Doom: The Growing Threat of Harmful Algal Blooms

This series provides deep context on algal blooms. Check out other posts about what causes them, their potential toxic hazards and hot spots around the United States. Go to FoodPrint to learn more about how industrial agriculture can affect our water.

Has the water in your swimming hole gone green with gunk?

What about a red sheen topping the ocean waves? Chances are that you are witnessing one of the many harmful algal blooms (HAB) that tend to pop up in the summer’s heat.

Harmful algal blooms are a serious problem in local ponds and in faraway waters. They have spelled “algal doom” by turning drinking water toxic and ravaging aquatic ecosystems. These HABs are a growing threat around the world as human development and conventional agriculture are creating more nutrient pollution. Add to that the high temperatures, heavier rains and more intense droughts expected with climate change, and HAB outbreaks might become even more commonplace – and troublesome.
