Bacterial world – Microbes that rule our world
Bacteria are everywhere: in the ground, in the water and in the air. There’s no creature on earth that’s not populated by bacteria. Scientists are exploring the complex role of microorganisms. How great is the invisible power of bacteria?
Bacteria are everywhere: in the ground, in the water and in the air. From the tiniest insects to human beings, there’s no creature on earth that’s not populated by bacteria. Scientists are only just starting to understand their complex role. Without bacteria, the human digestive, immune and even reproductive systems wouldn’t work. The human body contains ten times as many bacteria as it does cells of its own. Scientists are only now beginning to understand why. Without these tiny residents, many things wouldn’t work. Bacteria may have played a bigger role in the evolution and development of species than previously thought. Thanks to its symbiotic relationship with bacteria, the bobtail squid, which lives off the coast of Hawaii, is able to light up and defend itself against predators. A marine worm off the coast of Elba can feed itself without having a digestive system, and a species of wasp reproduces alone with the help of bacteria. How great is the invisible power of microbes? A fascinating documentary about the tiniest living things.
