Cargo Ships continues to carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. But in a Life After People, how will the cargo get transported?
1 Week after people: The crew is gone, but the ship is not quite abandoned. The rats have taken over and starts eating on the grain, But the rats won't just eat, they'll also breed. Female rats can have 6 litters in a year, with perhaps a dozen rats in each litter. And at the age of only 3 months, the young rats are themselves ready to breed.
1 Year after people: A pair of rats can produce 2000 offspring every 12 months, causing this cargo ship to experience a population explosion. The dark hold of the ship has been overrun by rats. The rats' need for half an ounce of water a day has been satisfied by rainwater. But with no one to work at the bilge pump, the cargo ship is starting to sink in the middle of the ocean. As sea water saturates the grain, thousands of rats flee to the upper decks, but they cannot desert.
2 Years after people: The rats have turned on each other. Every single of rats have died, from starvation or cannibalism. Their bodies are now food for the hungry sea birds.
