Ants!

The stupidity of human beings is to always making up for the loss at a lager expense rather than avoiding the loss.
I go to NUS every weekend for a quieter environment to study in and a more convenience attachment to the Internet. However, today is the first day that I find ants in our classroom.
I hate ants. Because they’re annoying crawling around me, especially when I am concentrating on my study. Anyhow, I don’t know whether I’ll have to suffer for the coming two months. At first, I would kill every ant as long as I saw it. But soon I found that the army was so large that I couldn’t kill even one tenth of them no matter what effort I made.
Suddenly, tutors’ instruction occurred to my mind—“No eating in the classroom!” I confess that I have ever eaten something in the tutorial room and it is what I feel regrettable about. Eating outside is nothing more tiring than walking several meters. On the contrary, killing so many ants or expelling them away benevolently costs much more time and energy. How I want to go back to what several weeks ago! Then I could enjoy my studying without disgusting ants.
Likewise, the entire human race shares the same character. When they are in good condition, they can’t find how precious the environment around them is. They pollute, pollute and pollute. Finally, they find themselves living unpleasantly with so much pollution. As a result, every country sets aside a large portion of its budget every year dealing with polluted nature resources, which costs much more than maintaining them. The phenomenon is particularly common and severe in China. Therefore, actually I am heart-broken while typing so.
After all, this sort of common fault cannot be eliminated only because of my word. I still hope human beings can walk less roundabout ways in the process of civilization. At least, I get to learn cherishing what I enjoy now and trying my best to maintain them.
