From the introduction: Welcome, Jumper, to the World of Captain Planet. It is a world not unlike your own, with cities and people you will no doubt find familiar. Like your world, the planet Earth is exploited by its inhabitants, its resources consumed recklessly in the name of profit. However, in this world, the consumption has grown beyond all pretense of reason. Pollution chokes the skies and fouls the seas; forests are razed to the ground and plants with and die. If this reckless destruction is not halted, the planet will soon collapse under the weight of its population. Thankfully, Earth is not without its protectors. Five young teenagers, guided by the Earth’s guardian spirit Gaia and gifted with the powers of the elements, have banded together from all corners of the globe. Their mission: to defeat the corrupt and ruthless beings who are destroying the planet, and to raise awareness worldwide on how to save their planet.
