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? Bubonic plague, typhoid and tuberculosis: over the course of human history, we’ve fallen victim to countless diseases caused by bacteria. But only around one percent of known bacteria are pathogens. This documentary looks at the microorganisms that live in the bodies of living things - from tiny insects to mammals such as humans. 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. 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.

Excelent video Documentary. But There was no need for the back ground music at all. There should never ever be kind of back ground music in films and video documentries. No music please.

All I can say is, the producers of this video have absolutely no conception of the extremely complicated process of DNA replication. They are smart, and I am glad they have researched so they can tell us these amazing things. But to assume time and chance brought this about is even more amazing than the fact that it is real.

YProblem with sience is that science believe that for any theory need to be experiment and if experiment is successful things are accepted as truth.but main believe of modern science is that life in general coming from material mather collide together and there is life.but this theory have no any practical experimental truth.this means sience believe in theory without experimental possible that scientists mix 2 matherial things and create not possible .we have practical experience that all life coming from life .any living beings have father .there is no any practical experience that from matherial ingredients life is coming.this means that science believe in main theory without any practical or experiment truth.for the and why Sience not do experiment to profe this statement that life coming from matherial ingredients.put 2 matherial ingredients together and make not possible .is like man is pretending to be milioner .you can speak to him ok you are milioner but I like to see at list 5 pounds .if he can not provide even 5 pounds that means he is not theling truth.similarly we can speak to scientists produse just one small life like ameba or virus or insect from matherial ingredients sience can not provide nothing .this means all this theory without any practical experimental just not this man he speaks he is milioner but if he can not provide even 5 pounds what is it.similarly science can not provide even one virus or bacteria from matherial ingredients what is it is just ridiculous

"All that can be invented, has been invented". When I see an incredible documentary like this. I can't help but think of where this will lead into new discoveries. The new discoveries and their possibilities help you to understand just how short sighted the no more inventions statement was. And then I see that there are 55 people who have disliked this video. I think they are the kind that stay trapped in the closed minded mentality that nothing else can happen or ever be invented.

lightdark00 - Go back and watch the video again starting from (21:00) for about 2 minutes. Listen carefully, this time. At (22:08), the researcher tells us, "What surprised us was that _food,_ geography, and also gender and age apparently have no impact." At (22:43), the narrator, talking about our _enterotype,_ tells us, "What type we are _does not depend_ on our environment, our sex, our age, or _even on our diet._ --------------------------------------- Your animal hugging ideas come from your evolutionary thinking. The Earth and it's diverse biosystems were designed and created for the benefit of Mankind. We may eat the animals or experiment on the animals or turn them into pets. They are here for us. We should respect and be good stewards of the Earth and its creatures because it is all Goᴅ's creation, but it is here for us. No animal thinks about Goᴅ or forms a relationship with Him - only people. Next time you take a shower, imagine all the animals you're destroying. Even cows get some proteins from bugs and bug eggs on the grasses they eat. Life comes from life.

This is great. I discovered DW docu thanks to my interest in systemic problems of society, and it proved very interesting. But then unlike many channels that criticize the status quo, this has some amazing and fascinating stuff that is done within the system. And it brings hope. (which is just another name for anxiety, but I don't care, this is a comment in English after all.)

To anyone who thinks this documentary is very interesting I'd like to suggest reading Ed Yong's book _I Contain Multitudes: The Microbes Within Us and a Grander View of Life._ It's a fantastic book that addresses many of the same topics from this documentary, is very well sourced (as you'd expect from a doctor in biochemistry) and really pulls you in. His TED Talk about parasites is fantastic by the way, Yong has a good sense of humour but he is also very capable at explaining simplified difficult concepts/topics without dumbing them down too much. The TED Talk is a good introduction into the way his book is written as well. Link:
