¿How does the topic 'Survival' appears in the movie? (120 words).

The topic 'survival' first appears when Pi stays alone in the middle of the ocean. He had to survive those two months with short food supplies. During the first days, he used the food from the boat until he relized that there was a mouse. As a result, he had to fish. Thanks to that, he had food. In addition, he had something to do instead of sitting down under the sun. However, this wasn't the solution.
Since Richard Parker, the tiger, got on the boat, Pi knew he was not gonna chill out. The tiger was a huge problem, what's more, it must be fed. Consequently, the food Pi had wasn't enough. Quite unexpectedly, a shoal appeared and they got enough food. Moreover, Pi used that like a way of getting into the boat.

Pi in his little boat he made for himself, a whale and the boat where Richard Parker was. (During Night-time).
