First, make the environment better and better. Maybe when you go out, you will find trees planted in many places. Because all kinds of trees can make the local environment better and better, trees can absorb harmful substances in the air. Therefore, after seeing uncle's behavior, everyone admired him and felt that uncle's behavior was worthy of praise. Because planting trees can not only beautify barren hills, but also make the environment better. Therefore, uncle's behavior has also been recognized by many people, and even some friends think that they can learn from uncle, because the environment will definitely get better and better.
Second, I want to change my living environment. For some people who live in big mountains, they don't have much chance to go out. Moreover, there are few kinds of trees on many mountains, because the environment on the mountains is relatively bad. So sometimes you will find that some mountains look bare and there are not many green plants on them. Uncle chose to plant trees because he wanted to change his living environment. Because these trees will be particularly lush when they grow up, and they will also change the color of the mountains and make people living nearby feel better and better.
Third, many people feel very moved by summing up uncle's behavior. Because in this process, uncle spent a lot of money to plant trees, and all at his own expense. Therefore, many people think that uncle's contribution to his hometown has also benefited some hometown folks. So everyone thinks that uncle's spirit is worth learning, because a variety of trees can not only make the environment better and better, but also benefit the local economic development.
