The sinking

In the life of pi, lots of interesting things happen,  and most of them are cause and effect cycles ( when someone does something and that effects something and that effects something else). The main event is when the ship sinks.

                pi wakes up and notices something isn't right.
                So the ship starts to sink and that’s the cause. So pi and everyone on the boat wants to get on the lifeboat and that’s an effect. There’s a hyena  on the boat because it jumped in there before everyone else, and that’s a cause.If the hyena didn't get in everyone else would and later everyone would probably be eaten By Richard Parker or they might have starved. Subsequently, pi is let on the lifeboat first  because no one wants to get in (pi doesn’t know there are animals in the lifeboat)and that is another effect. If pi didn't get in he would have died.   A lion gets in the lifeboat, that’s a cause. Then the hyena, a zebra and a few mice get eaten, that’s an effect.
