The Amazon Rainforest, the largest and richest ecosystem on earth, has stood inviolate for thousands if not millions of years since its creation. The profusion and variety of life forms present in the rainforest and its critical role in supplying the world with air has resulted in its being called the "Heart and Lungs" of the planet. Indeed, the majority of the world's oxygen is supplied by its dense foliage and teeming plant life which upon first inspection, seems boundless and indestructible.
