Shrews are the smallest mammalian predators on Earth. The Etruscan shrew (Suncus etruscus), weighing only 2 grams, is the smallest living terrestrial mammal.
They are so tiny that their energy expenditure per unit mass is the highest amongst all mammals, so much so that they require 3 times their own body weight in food just to stay alive, making them gram-for-gram the most voracious predators on Earth.
Someone once kept 3 shrews in a terrarium. One day, he was late for work and forgot to feed them. Guess what he found in the terrarium when he came home in the evening?
A lot of shrew droppings, and the front half of one shrew.
Finally, he figured out what happened: First, two of the shrews killed and ate the third. Second, one of the remaing two killed and ate the other. Third, in desperation, the last shrew ate itself alive from the tail up.
This means that an animal would rather eat itself alive than starve to death.
The 200 or so nations on the planet today are like the three shrews in the terrarium. Think about it.
