What I want to learn about CP

What I want to study about computer is how to make effective homepage. It relates to my dream. It is to solve the environmental problems and to improve the developing countries life. In the future, I will try to go to some countries to see these problems directly and work for them. Moreover, my purpose is to tell this truth to other Japanese who do not know it or think it not so seriously. I think the homepage is one of tools to introduce own idea for many people, and it is why I want to make the good quality homepage to achieve my dream. Now, I feel difficulty to show my thought about volunteer, through the volunteer work at NIC. Therefore, I will try to think what kind of homepages attracts people and able to tell them my thought correctly in this class.
