Travel the world, and you'll see animals, insects, plants... Among stone, water, and air, this little world bustles about, composing endlessly varied living tableaux. The grown-up word for these? ecosystems.
Starting point: the temperate woods. Then dive into the river and surface far, far away... on a fine, sandy beach. The voyage continues with a coral reef, a tropical rainforest, the savannah, and deserts –tan and hot for the Sahara, white and frigid for the Antarctic. Our journey comes to an end in our own bodies, hosts to helpful bacteria.
