The Wump World

Resumen

The Wump World by Bill Peet is a children's book taking place on an imaginary planet. It is about the near destruction of the only habitat of creatures known as Wumps. These Wumps look somewhat like a cross between a capybara and a moose.
The story about these Wumps takes place on their own planet, hence the name The Wump World. A race of blue humanoids named the Pollutians overruns the Wump World, causing the Wumps to flee to the safety of underground caves. The Pollutians build great cities and colonise, dirtying the air, water, and plowing down entire forests and grasslands, which the Wumps rely on for food and water. The Pollutians reach trouble when the air becomes too polluted, and their leaders send scouts to search for another planet. One scout returns, claiming that he has found a bigger and better world; upon hearing this news the entire Pollutian populace leaves the planet, leaving their thickly polluted cities. When the world above grows quiet, the Wumps emerge to find a changed world, a deserted "concrete jungle".
