Our presentation

  I looked and listened my class presentation ,I learn about environment a lot.
Also,I studied about animal experimentation and an endangered or extinct species,I knew many things about animal,why animal extinct ,why scientist do animal experimentation,and it is really necessity・・・
 These problems makes me think many things.

Nara

January 9, I went to Nara whit my class member.
Nara is very great place. there are many beautiful temples and shrine.
I can feel mystic space.
  Moreover there are many deers in Nara,we can touch them,and we can see the figure which deer run in the forest.That figure was very cute and made me happy.
 And we met a people who work as eco taxi driver.
His work is　carrying people by Man-pulled car.
When I saw his car, I thought I wanted to ride, but it's very expencive.
So,we couldn't ride that.

Animal Experimentation

Today I study about Animal experimentation for this class prezentation.
That content made my feeling bad and sad,that is very cruel content.
I think that Animal experimentation do not need now,because it is cruel 
Moreover to my surprised, the present science doesn't need Animal experimentation.
Even if Animal experimentation　not,we can produce various of medicine by another way.
So,I think that we should ban animal experimentation .

Ozone Layer

  I　study about Ozone Layer a little.
Ozone Layer is made of three oxygen atoms、it is protect  us from bad  ultraviolet by　absorbing .
If ,when we have a lot of exposure to ultraviolet light,may damage DNA ,cause cancer.
  Ozone Layer protect us　from these dangerous,but  Ozone Layer have been destroying by Freon. already ｔhere are very big Ozone hole
So "Vienna Convention for the Protection of the Ozone Layer" and"Montreal　Protocol on Substances　that Deplete the Ozone Layer"are adopted,but I worry about Ozone Layer and earth.
