2 days ago, I watched a movie published by BBC in the cinema. The quality of the movie was very delicate, the sound and special effects were also top-notch. Nevertheless, the content of the movie was the most shocking bit. The movie was about the world's environment getting worse. After the movie ended, I felt very heavy-hearted. Everything we human beings need to be able to survive comes from the Earth; without it providing resources, we will have no change of surviving. However, humans' constant demand for resources has lead to deteriorating environmental conditions. Eventually, the Earth will not supply us with our needs to survive.
