eutrophication

• Substantif désignant le processus par lequel un plan d'eau s'enrichit excessivement en nutriments, souvent à cause d'apports d'engrais, d'eaux usées ou de déchets d'élevage, entraînant une croissance massive de plantes dont la décomposition épuise l'oxygène et provoque la mort de la vie animale.

A noun referring to the process by which a body of water becomes overly enriched with nutrients, often from runoff containing fertilizers, sewage, or animal waste, leading to dense plant growth whose decomposition depletes oxygen and causes the death of animal life.

The subsequent decomposition of this organic matter depletes oxygen levels, harming aquatic life.

   • Agricultural fertilizers are a major cause of eutrophication in lakes and rivers.
   • Eutrophication can lead to dead zones where fish and other organisms cannot survive.
   • Scientists monitor nutrient levels to prevent eutrophication in coastal waters.
