Recently it’s warmer, and windier. As the wind blows garbage everywhere, we went to the park to pick up garbage. Looking at the garbage on the ground, many of them are thrown by people. Long time ago, we also have this bad practice. For our own benefits, we threw garbage everywhere, and thought it’s okay. Uncle corrected our bad habits. Or else, everyone throws their garbage everywhere, and no one cleans up them, it’s hard to imagine what the environment will become after some time.
