I am writing an English paper wherein I have to appeal for change in the way humans treat wildlife. I was initially given a situation wherein I took a ferry in a certain area and saw a dead baby dolphin.
Along the way, I (it is written in second person) apparently notice how little water is now available for the dolphins (due to some bridge being constructed).
What exactly is bad for dolphins (or animals in general) when they have limited space to roam around?
So far I thought of dolphins hitting boats due to the crowded state of the area in question.
