There is a map of the world. There is a large island, separated from the main continent by a narrow channel, circled.
This is Baravi. Baravi is a big, nice country with lots of grazing animals.
A long time ago, Baravi did not have any rabbits.
North of Baravi is Litholee. They did have rabbits. Actually, almost the whole world had rabbits - but not Baravi.
Because they were an island, no rabbits had gotten there.
Until one day, someone brought rabbits to Baravi.
We do not know who it was. It might have been a visitor who had a pet. It might have been a careless cargo ship with some rabbit stowaways. It might have been someone who wanted Baravi to have rabbits.
Whoever it was, they made a very bad mistake!
Rabbits had lots of baby rabbits. The baby rabbits grew up and had baby rabbits. And soon Baravi was overrun with rabbits!
In most places that have rabbits, there are also foxes and hawks, which eat rabbits. That means that there are never too many.
But in Baravi there were too many. There were rabbits everywhere. There were rabbits eating all the crops. There were rabbits destroying all the grazing land. There were too many rabbits.
Baravi decided to send their army. They taught them how to kill rabbits and they sent them out to kill as many as they could.
They did this for years!
There were still rabbits!
They sent more people with better weapons!
There were still rabbits!
Baravi did not know what to do.
What would you do?
Baravi asked their greens!
The greens said that the rabbits were probably here to stay. But there would not be as many rabbits if there were rabbit predators.
Baravi did not want to add more animals! That sounded very bad.
Some greens had a clever idea. They came up with a rabbit flu! They said it could kill all the rabbits.
Other greens were worried. They thought the rabbit flu might get people sick. They had to test it carefully.
After lots of testing, they were sure they had a rabbit flu that would not hurt any people.
Helicopters dropped it on fields.
Most of the rabbits went away.
But not all of them! Some rabbits did not get the flu. And their babies did not get the flu either.
Baravi greens tried again. They made three rabbit flus! No rabbit would be immune to three rabbit flus!
This time it worked.
Doing all of this cost Baravi lots of money - it was as expensive as a normal war.
And lots of Baravi farmers suffered while there were rabbits eating their crops.
Everyone learned that the best way to win a war with rabbits is to catch it before it starts.
Island countries have strict rules when people come to visit - to make sure that they don't have a rabbit in their bag!
