A small change can make a big change. (Yoona Hahm)

According to the article "A slow walk of trees", it shows changes of beliefs about abilities of black people. In the past, it was impossible for black people to do something. Also, the author's grandfather and his father thought so. Even though his grandmother and his mother thought more positively and tried to open minds, there was many restrictions on black people.

However, "like the slow walk of certain species of trees from the flatlands up into the mountains," the society where we live is changing. Nowadays, there are more opportunity for black people to do what they want unlike in the past which has restrictions. Our society tries to provide a chance impartially. This small tries and changes make a big change. The new president of the United States is the representative example. Nobody, in the past, could not imagine the black president. However, it happened through small changes.

Of course, the discrimination still exists. However, it is getting disappear. Maybe the change looks so tiny and so small that we can not recognize it. We can not notice the big change like this example until a few decade years later.
