Assignment Example It is only by changing the mentality of human particularly the fishermen that the aquatic life will be protected from possible extinction. It is wrongful for a few individuals to engage in practices that benefit only a few but has dire consequences suffered by all. A good example is overfishing, which destroys aquatic life affecting even those who do not practice it. 2. How were your views and opinions challenged or changed by your reading of In Pursuit of Giants, if at all?   Before reading this book, I considered humans dynamic in that they can change their behaviors depending on the situation. However, reading this book made me realize it is not always the case.

Mid-water trawling is another commercial fishing method commonly used in different parts of the world and entails immersing nets net in areas with high water volume.
