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.
I looked your presentation. It is very interesting for me. And I could learn many things from your presentation. I think we should think about endangered species. Thank you.
