  • Hey there!

  • Welcome to Life Noggin.

  • Oh look it's my invisible friend!

  • So glad you finally got to meet him!

  • Living in the water, and nearly everywhere else on Earth, are tiny, microscopic organisms

  • called microorganisms or microbes.

  • They have existed for at least 3,500 million years and were the only living things on Earth

  • for the majority of that time.,, Different types include bacteria, archaea, fungi, protozoa,

  • algae, and viruses.

  • Microbes are able to survive in harsh environments like hot springs, the Dead Sea, and Antarctic

  • ice, as well as ordinary places like swamps, rivers, and soil.,

  • And there are a whole lot of them out there.

  • Overall, they make up about 17 percent of Earth's total biomass, which is the weight

  • of every living thing here.

  • In the sea alone they are extremely abundant.

  • In all of the world's oceans, they make up 98 percent of the total ocean biomass., Yeah,

  • there are millions upon millions of tiny little communities that you probably haven't even thought

  • about!

  • While not all microbes are harmful, there are definitely some to watch out for that

  • cause foodborne illnesses, and infectious diseases.

  • These include the bacteria Mycobacterium tuberculosis, that can cause tuberculosis, the protozoan

  • Plasmodium, which causes Malaria, the fungus Trichophyton rubrum, which causes ringworm,

  • and the virus Varicella zoster, which causes Chickenpox.

  • These and other disease-causing microbes are called pathogens.

  • If we come into contact with them and they enter our bodies, they can cause an infection

  • by damaging our cells and could even challenge our immune system by killing or disrupting

  • cell or tissue function..,,

  • Some of these harmful microbes can make their way into drinking water through feces and

  • cause diseases like cholera, typhoid fever, and dysentery., The World Health Organization

  • estimates that over two billion people around the world use a drinking water source that

  • is contaminated by feces, resulting in nearly half a million deaths.

  • But, as I said, not all microorganisms are bad.

  • In fact, without them, we wouldn't have pizza bagels!

  • Fungi like yeast are used to make bread and beer, and mold is used to make some cheeses.

  • And, because microbes create oxygen while processing greenhouse gases, they could potentially

  • be an option for fighting climate change.

  • Scientists have already found a way to use E. coli bacteria to make biofuels.

  • Marine microbes play a big role in maintaining the health of coral reefs and the recycling

  • of their nutrients.

  • They also help clean our own water at wastewater treatment plants, where they are used to eat

  • biodegradable materials.,

  • Helpful microbes can even be found closer than you may think.

  • On and inside our bodies are trillions of microorganisms., Some of these microbes help

  • with digestion, protect you from infection, and maintain your reproductive health.

  • That's right the tiny communities living on and inside you are working very hard!

  • No need to panic about that thought at all.

  • But just because they are helpful ones, that doesn't mean you shouldn't protect yourself

  • from potentially harmful microorganisms.

  • So, remember to wash your hands often, keep your immunizations up to date, and make sure

  • your drinking water is clean.,,

  • So, what do you want me to talk about next?

  • Let me know in the comment section below right now and you're suggestion can become a future

  • Life Noggin episode!

  • Curious to know what the heck this is?

  • Yeah, you're gonna want to check out this video!

  • Thank you so much for watching and liking this video!

  • As always my name is Blocko!

  • This has been Life Noggin!

  • Don't forget to keep on thinking.
