    Imagine possessing something that you loved so much. Imagine what it would feel like if you lost it. While that item may be something as simple as a toy, you would still feel very upset, but you could replace it with a new one. Now imagine losing something that you depend on for survival and cannot be replaced. That is what it would be like if we lost the natural environment around us.

Firstly, I believe the environment should be protected because it supports human life. One of the largest examples is that we get all of our food and drinks from the environment. If the environment were to be destroyed beyond revival, then the human race would be over in months. Scientists have to find another planet with similar conditions to the Earth, and if it's found, we don’t have the technology to get to that planet in time.

Secondly, I believe that the environment serves as an amazing educational tool for students. When I was in second grade, I had an absolute interest in animals. When we had a field trip to the Daggerwing Nature Center, I was very excited. When we got there, I could hardly believe what I was seeing. There was a bridge to get to the main building, and under the bridge was a small swamp (沼泽) with turtles, fish, and my personal favorite, alligators. I was so surprised that I almost ran into the tour guide. We walked into the building and saw various animals in their habitats. I was so inspired by this visit. Six years later, I have taken an animal behavior class for three weeks. Meeting by chance with the environment can inspire people, and if preserved, it will continue to inspire people.

In conclusion, the environment is so valuable because it can't be replaced, keeps us alive, and serves as a great educational tool.
