Incomplete question. I assumed you are referring to the article <em>"Excerpt from Marine Mammals in Captivity" </em>by The Humane Society of the United States.
<u>Explanation:</u>
In that section, the author provides real-life examples that back his claims about why animals should be taken from their natural wild habitat.
For example, the author stated, <em>"The very nature of these animals makes them uniquely unsuited to confinement." </em>He further continued by stating how Whales and Dolphins naturally love to travel long distances every day,<em> </em><em>"they are always aware, and always moving."</em>
The author made a lasting point by adding, <em>"Understanding this, it is difficult to imagine the tragedy of life in no more than a tiny swimming pool." </em>With such expression the author no doubt causes the reader to think about the sudden changes experienced by these living organisms.
