algal bloom
Pond's green explosion
An algal bloom is a rapid, excessive growth of algae in a body of water, often triggered by nutrient runoff from fertilizers or sewage.
Blooms can turn water green, red, or brown and may produce toxins harmful to fish, wildlife, and humans.
The lake was closed due to a toxic algal bloom.
