Several times ago, the red cross was lack of blood.Meanwhile blood is one of the most important thing that is used by red cross to do their task helping people. By donating a little of our blood, that means we already help people to survive.
There are still 9 millions Indonesians people that are illiterate and 5 millions of them are women. As good students we can help them by teaching them how to read , write, and calculate. By doing all of those activity, it means that we already participate in supporting government to decrease illiteracy in Indonesia. We also take a role in educating the children that will be Indonesia's future leaders.
Indonesia is a country located in “ring of fire” so it makes Indonesia frequently attacked by several natural disasters such as Tsunami, earth quake, volcano eruption etc. Reacting to those phenomena, as a student, things that we can contribute beside of giving money is to be volunteer, because we still have strength to directly help those who needs.
