Could humans live in underwater city?

    Hello, everyone! Today, I'll introduce a podcast which I watched. The title is 'Could humans live in underwater city?'

    In this podcast, whether we human try to live in the sea and what problems are of living in underwater are explained. First of all, there is a project to live under the sea, and Japanese team is leading it. One of the member of the project team said that it is our purpose to solve environmental problems like lack of natural resources. At seabed, there are a lot of resources, for example, oil and shale gas. He insist that if we can use the resources, we will not have to suffer from shortage of it on the ground. 

    However, there is mainly one big physiological problems when we live in underwater city. First problem is that we have to worry about the bends, a disease caused by the differences of atmospheric pressure between on the ground and under the sea. Because of the bends, even ex-military person could live in underwater only about 70 days. Divers have to readjust to environmental change, so ordinal people maybe are difficult to control their condition. 

    When I listened to this podcast for the first time, I thought that it is good idea to live under the sea, and I hoped that physiological problem can be solved. However, I also think that this is a temporary solution to solve the shortage of natural resources. Even if we can use new natural resources, it is nonsense as long as we think carefully about how to share resources with other people and how to use it. If we don't learn from our history, we will repeat the history!: We will again face to the lack of resources. Thus, I think this is interesting idea, but we have to find other means to solve environmental problems.

    Thank you for reading! What do you think? If you have any idea, please tell me on comments casually!

    This is a very interesting article! I see that living underwater would cause many problems because of the different condition. However, solving the problem may show us how you can live in space! Of course living underwater is a temporary solution, but living in space would be a permanent solution! Imagine our descendants will live like space nomads!

      Thank you for your comment, Keita-san!
      I 'm convinced. I also think that if living in underwater is applied for living in space, we can solve our problems permanently because space is said that it continues spreading now and there are a lot of place which we human don't know.
      Your idea is very interesting!

History of Otoshidama

イメージ
     Hello, everyone! Did you enjoy the last winter vacation? I do hope that you had a good time during the New Year. Today, I will write about the origin of Otoshidama  (お年玉).    　Why Japanese adults give their money to children on the New Year's Day? It is said that this custom had been related to "Year God(Toshigami-sama,歳神さま in Japanese)," who had been worshiped in each family during the New Years holidays. People worshiped Toshigami-sama because they believed that the God brought abundant grains to people. Also, people thought that they could be health and make a lot of grains during the year if they gave rice cakes, which were made for the God, to their family or servants.      Japanese people thought that the rice cakes were sacred things. Therefore, it is said that people called the rice cakes "rice cakes like gems( 玉( Tama ) のような餅)." Also, some people called "the soul of Year God (歳( Toshi )神様の魂( Tama shii))," so the rice cakes became to be ca

Melting ice sheet: Is it too late?

     Today, I listened to "Melting ice sheet: Is it too late?" In this pod cast, the man and the woman talked about melting ice sheet of Green land and the Arctic and whether it's too late for human beings to strive to stop global warming.       Michalea King, a glaciologist, explained that usually, the amount of melting ice sheet and the amount of newly frozen ice was in balance, so we do not have to worry about melting ice sheet. In other words, "the amount of ice being drained from the glaciers was equal to what we are gaining on the surface via snow every year."(This is a citation from her words.)       However, recently, the glaciers have been melting faster than ever, and the balance was destroyed. She said that the situation which we are now facing is the tipping point. In fact, 500 gigatons of ice are now melting into the ocean every year, and the amount of newly frozen ice is less than that. Gigatons stands for a billion tons.          Michalea also sai
