You hear people on the news talk about it. It gets politicians worked up and scientists worried. Every walk of life from a humble office worker to a big shot celebrity is helping to lessen the problem. What is the problem anyway? We call it the HEP, every human-caused problem affecting the earth from climate change to resource deficiency. Whatever you call it, its effects are still the same. The human population is overcrowding and polluting the Earth to such an extent that, if we don't stop, the world as we know it could end in less than a decade. Although the cause seems unlikely, if you go green, you are not only becoming more eco-friendly but also inspiring change for others.
