あなたのミネラルウォーターの中にいるかもしれない微生物！

今回は Life Noggin - YouTube から、水中の微生物の動画です！

淡水にも海水にも飲み水にも、無数の微生物が存在しています。

勿論、人が生きるために必要な微生物もいますが、病気を引き起こす微生物もいます。

どういった場合に気を付ければよいのでしょうか？

それでは今日もYouTube英語学習を楽しんでいきましょう！

Hey there!
00:01
Welcome to Life Noggin.
00:02
Oh look it’s my invisible friend!
00:06 (I'm-)
So glad you finally got to meet him!
00:07
Living in the water, and nearly everywhere else on Earth,, are tiny, microscopic organisms
00:14
called microorganisms or microbes.,
00:17
They have existed for at least 3,500 million years and were the only living things on Earth
00:24
for the majority of that time.,, Different types include bacteria, archaea, fungi, protozoa,
00:30
algae, and viruses.
00:32
Microbes are able to survive in harsh environments like hot springs, the Dead Sea, and Antarctic
00:37
ice, as well as ordinary places like swamps, rivers, and soil.,
00:42
And there are a whole lot of them out there.
00:44             =account                                                     そうやって(17%は微生物な状態で)
Overall, they make up about 17 percent of Earth’s total biomass, which is the weight way
00:49 地球上の生物は生きているのです。
of everything living thing here.
00:51
In the sea alone they are extremely abundant.
00:54
In all of the world's oceans, they make up 98 percent of the total ocean biomass., Yeah,
01:01
there are millions upon millions of tiny little communities that you probably have even thought
01:07
about!
01:08                                                                                    s/↓microbes        /
While not all microbes are harmful, there are definitely some to watch out for
01:12 /v    /o
that cause foodborne illnesses, and infectious diseases.
01:15 (難しければ病名は流してもOK、ただし)
These include the bacteria Mycobacterium tuberculosis, that can cause tuberculosis, the protozoan
01:21 (fungus,chickenpox,pathogenはよく出るので覚えよう！)
Plasmodium, which causes Malaria, the fungus Trichophyton rubrum, which causes ringworm,
01:27
and the virus Varicella zoster, which causes Chickenpox.
01:31
These and other disease-causing microbes are called pathogens.
01:35
If we come into contact with them and they enter our bodies, they can cause an infection
01:39
by damaging our cells and could even challenge our immune system by killing or disrupting
01:45
cell or tissue function..,,
01:47
Some of these harmful microbes can make their way into drinking water through feces and
01:51
cause diseases like cholera, typhoid fever, and dysentery., The World Health Organization
01:57
estimates that over two billion people around the world use a drinking water source that
02:02
is contaminated by feces, resulting in nearly half a million deaths.
02:06
But, as I said, not all microorganisms are bad.
02:10
In fact, without them, we wouldn't have pizza bagels!
02:13
Fungi like yeast are used to make bread and beer, and mold is used to make some cheeses.
02:19 微生物は酸素を生み出して温室効果ガスを処理するので
And, because microbes create oxygen while processing greenhouse gases, 
02:25 気候変化を防ぐ一つの選択肢になり得る
they could potentially be an option for fighting climate change.
02:27
Scientists have already found a way to use E. coli bacteria to make biofuels.
02:32                                              サンゴの健康維持 と サンゴの栄養再利用
Marine microbes play a big role in maintaining the health of coral reefs and the recycling
02:37
of their nutrients.
02:38
They also help clean our own water at wastewater treatment plants, where they are used to eat
02:43
biodegradable materials.,
02:45                    身近にも見られる
Helpful microbes can even be found closer than you may think.
02:49 体表面にも体内にも
On and inside our bodies are trillions of microorganisms., Some of these microbes help
02:56
with digestion, protect you from infection, and maintain your reproductive health.
03:00 そう、その小さな生物群が体の表面と中で懸命に働いているのです
That’s right the tiny communities living on and inside you are working very hard!
03:05 (体で微生物が働いていることは)心配無用
No need to panic about that thought at all.
03:07
But just because they are helpful ones, that doesn’t mean you shouldn’t protect yourself
03:12
from potentially harmful microorganisms.
03:14
So, remember to wash your hands often, keep your immunizations up to date, and make sure
03:20
your drinking water is clean.,,
03:22 知りたいテーマがあればコメントしてね！
So, what do you want me to talk about next?
03:25
Let me know in the comment section below right now and you’re suggestion can become a future

03:30 (Are you curious-?)
Curious to know what the heck this is?
03:33
Yeah, you’re gonna want to check out this video!
03:47 (Water bearのくだりの字幕がないので、自分で頑張って聞き取ってみましょう！)
Thank you so much for watching and liking this video!
03:50
As always my name is Blocko!
