World War Z chapter 4: The Great Panic

The chapter the Great Panic is really about how people are coming to terms with what is happening and their experience in the Great Panic. The part the stood out to me the most was how people were running to the coast to get on the boats and even swimming to get to them; and the people that swam got pulled under by the zombies the boats were throwing overboard. I cringe at the thought that because Zombies don't need air to breathe, they can literally just walk along the bottom and then, eventually, walk onto any land.
