    • Troubles with sea otters population

    • The topic of the lecture is the causes of the decline of the sea otter population.
    • From that premise arise two possible hypotheses.
    • In one of them, the writer points out the importance that could have had the pollution near the sea.
    • The second one is that several otters were hunted by their predators.
    • The most accepted one is the first.
    • A few samples of seawater had been taken near the Alaskan coast and was discovered the existence of some chemicals which could have been crucial for the death of many otters.
    • The death of seals was another clue that led to this hypothesis because pollution not only attacks otters but also other animal species.
    • Only predators scattered in a large area, such as orcas, could achieve the same effect, but these prefer to hunt larger species than otters.
    • One curiosity about the death of otters is that most of them died in a small area near the coast, whereas another stayed alive in the same sea, but in a different zone.
    • That could be explained by a high pollution concentration in the areas where these animals passed off.
    • Rather than the pollution hypothesis, the guy who speaks believes that the otters were hunted by predators.
    • The orcas prefer to hunt whales, but on the Alaskan coast there aren’t any, so they have to hunt otters instead.
    • Besides, orcas have access to the zone where otters stay.
