I went to the Harvard Museums. There are many animals, plants, and insects on displays, and I found it very interesting to learn about the ecosystems of marine and land organisms. There was also an exhibit on global warming. Many issues such as climate change, destruction of coral reefs, air pollution caused by factories, destruction of ecosystems caused by wildland fire, etc. were displayed with sentences in each booth. It made me think, but at the same time I felt terrible to think that human beings have so many problems. However, there were many evidences such as videos, photos, and results of experiments, for example, digging underground and displaying geological strata, which persuaded me and made me feel that it was no one else’s problem.
