We know that PM is harmful for us, but we can't explain where PM has negative impact of our body so I wondered it. I think the brain plays very important role in our body, and consequently I became curious about what consequence it brings to the brain.

"Ironic, isn't it: we are investing in our children's future, we are sending them to school everyday to expand their minds (중략), and yet the air they breathe while waiting for the school bus is influencing negatively the development of the brain." This part impressed me because it was shocking that many parents make a lot of efforts to develop their children's brain but they might not know even before their children arrive at school, their brains are getting damaged.

I learned the impact of the PM to our brain such as damage of the central nervous system, encephalitis, Alzheimer's and that impact is wide from foetus to adults. All people has a brain and there are so many bad impacts of the PM on their brains but they are indifferent, saying "It'll be fine cuz for now we are okay.". I recalled the change of the atmosphere during 2020 when covid-19 started. Like this, we can solve this problem if we have will to solve it, in that I hope that people realize the seriousness of the PM and we see the blue sky continuously. 

So, I decided to find out what the earth would be  in the future and what is going to be like if human damage nature same as now. There may be several problems with this, but I selected one topic and explored in depth, and that is the story of the permafrost.

Most people are aware of the existence of this permafrost. However, not many people know the details of the enormous impact of this permafrost. So did I.

Once this layer thaws, the peat decomposes and releases carbon, not carbon dioxide as we know it, but methane, a powerful greenhouse gas. It can cause a much larger temperature surge than carbon dioxide.

Also, if the ancient virus that lived in the permafrost is leaked out, the antibiotics we depend on today are powerless because they have never been exposed to them. That could give rise to unbelievably  powerful strains of microbes that would eventually harm us.

There are many other problems including the permafrost, so I want to raise awareness about global warming and inform many people about them(problems)

Also, I thought I should work hard to protect the environment.

By doing this challenge, I could understand better about the chapter we learned.

In addition, as I picked up trash on the street, I thought I should voluntarily pick up trash more often.

Lastly, I think I should work hard to protect the environment with my friends for future generations

I was surprised that the unexpected ingredient became the main ingredient of Ooho, so I found this ted video while looking for information about seaweed. 

Until I watched this video, I didn't know the function and advantages of seaweed, but I'm very proud that I learned a lot of information through this opportunity. The most impressive thing about this video was the fact that seaweed, the main content of the video, absorbs carbon dioxide through photosynthesis, and seaweed is emerging as a shield against global warming. This video introduces the possibility of carbon capture in seaweed, explains how marine seaweed cultivation can capture all the carbon that we emit into the atmosphere on a large scale, and shows that seaweed absorbs carbon dioxide through photosynthesis. So far, I've thought that the only way to stop global warming is to reduce emissions of carbon dioxide and harmful substances, and it's amazing to know that there's also a way to reduce the carbon ratio in the air by absorbing carbon using seaweed. There's something I felt the most during this promotion. And as the speakers in this video said, half of the CO2 in the air right now is what we've emitted in the last 30 years, and if we've emitted it in 30 years, we can remove it in 30 years. I felt the hope that if we cooperate and work together from now on to reduce emissions and practice in various ways, we will live in a much better environment in the future. If I become a teacher later, I want to tell children what I realized.

While I was thinking about how to solve environmental pollution, I learned about him and the bacteria that broke down plastic from the virus I learned in life science class
This bacterium breaks down the plastic and gets the energy it needs This could help us where we dispose of plastic.

Bacteria are a variety of species that live everywhere, and they exist in extreme environments, and they have as many different food sources as they do.

Although there is a problem that bacteria decompose plastic slowly, research can help increase the rate of decomposition or increase the amount of growth.
Through this survey, it was interesting that life science can help environmental problems, and it was impressive that science fields interact with each other and solve problems.

I regret that I was ignorant about the environmental pollution problem before, and I vowed to pay more attention to the environmental pollution problem in the future.

The most memorable thing in this documentary was, "People shouldn't be afraid of sharks in the ocean, they should be afraid of not having sharks in the ocean." Do you know what does this mean? Now, many sharks are dying from shark finning. Shark finning means catching sharks, cutting fins, and throwing the body out of the ocean.

The only reason this is happening is because of the demand for shark's fin. People kill 11,000 to 30,000 sharks per hour. What happens to the ocean if this behavior continues and sharks become extinct? Sharks are apex predators. So they are at the very top of the food chain(level one). They eat level two. When we take away level one, level two then overpopulates. And level two eats level three. So they'll actually overpopulates. They'll wipe out their food supply, which is level three. And then, level two's got nothing to eat. So level two then disappears, and they go extinct. And it carries on down the food chain, down to the smallest organisms. I reflected on that i thought 'What's wrong with sharks disappearing?'

It was shocking to me that sharks are becoming extinct even though they play an important role in the ocean. But what's even more surprising is that I've only introduced one hour and half of this documentary, and it tells us a lot of realities about marine ecosystems and fisheries that  we've never been interested in, so I hope you guys watch this at least once as a person who lives on Earth

What I think I did well unlike other friends is that I was the only one who used the electronic receipt to protect the environment.

I didn't drink water often, so I didn't drink water using a tumbler, but I decided to use a tumbler when I drink water in my daily life, not a mission.

All missions are things that you can do in your daily life, so even after the missions are over, you'll keep them for the environment.

If many people pay more attention to the environment, environment destroy speed will decrease.
