If is not too much to ask for TOEFL PRACTICE 2 Hello guys ^^ I am practicing my writing skills on my own with youtube videos. If there is any possibility that you get a look to a youtube video ( the link is below ) and watch the first 15 min (if is not too much to ask :( ) please let me know how I am doing. I really appreciate all your help ^^ https://www.youtube.com/watch?v=eG2nypYexgM The reading passage makes a statement of sea otter population decline. States two theories about this. The first theory is that pollution should be laying industrial chemicals through the Alaskan coast and this makes these mammals get infections and thus ride them to death. The second and less probably theory is that these mammals are attacked by predators like orcas, but orcas usually eat bigger prey, like whales. In the lecture, the Professor makes a statement that the decline population of sea otter is by being attack by orcas. Because she states some important points. The first point is, that if the reason is pollution and these mammals are getting infected and die through the alaskan coast, there is no evidence because the bodies of the dead animal are not founded. The second reason is, that whales are the common prey for orcas but human hunting scare whales and make them go away from the orcas normal environment . Because of this, the only prey available to hunt is small mammals like sea otter, sea lion and seals. This makes orcas adapt to their needs. The third depends on location, otter seal and orcas avoid a shady and rocky environment because otter seal can not climb and orcas are too large to comfortably swim in this kind of environment. This is why both share the same location and make these small mammals easy to hunt.
