The creature next to me is kind of sea mammal which has already become extinct. We know that the speed of ongoing extinction of species is become higher and higher due to human beings' activities. The biodiversity is decreasing gradually. However, without animals, human beings will also extinct. We should "love, respect and admire" our earth.
I was born and grew up in China. As a result, my knowledge about American history is very limited. However, the tour of the Natural History museum provide a chance for me to learn more about the Native Americans. The museum helps us step out of our ordinary lives by building up a scene of the ancient Indian people's life. By doing so, we can understand the mystery of history and nature more easily because of the vivid exhibition.
