A large number of sea lions and dolphins have been found on the shore in California, dead or dying from a neurotoxin called domoic acid. This toxin is produced by algae that grow in the ocean and are eaten by fish, which are then eaten by sea lions and dolphins. Experts think that the algal blooms are caused by agricultural runoff and warming oceans due to climate change. A group of volunteers from the Channel Islands Marine and Wildlife Institute (CIMWI) are trying to rescue and treat the sick animals, but they are overwhelmed by the number of calls and cases they receive every day. They say this is the worst outbreak they have ever seen.

Let's look at some interesting expressions from the article that you can learn:

  • stranded: unable to leave a place or situation
  • algal bloom: a rapid increase in the population of algae in an aquatic system
  • runoff: water that flows over land into rivers or lakes after rain
  • disorientation: a state of confusion about where you are, where you are going, or what is happening
  • floodgates: something that controls or limits something else
  • flush out: to remove something unwanted from a place or system
