the red cross
the red cross is an international organization which cares for the people who are in need of help. a man in a pairs hospital who needs blood, a woman in mexico who has been injured in an accident, and a family in india that have lost their home in a storm may all be aided by the red cross.
the red cross exists in almost every country around the globe. the world red cross organizations are sometimes called the red crescent, the red mogen david, the sun, the red lion. all of these share a common goal of trying to help people in need.
the idea of forming an organization to help the sick and the wounded during a war started with jean henri dunant. in 1859, he observed how people were suffering on a battlefield in italy. he wanted to help all the wounded soldiers, paying no attention to which side they were fighting for. the most important result of his work was an international treaty called the geneva convention. it protects prisoners of war, the sick and the wounded, and other citizens during a war.
the american red cross was set up by clara barton in 1881. today the red cross in the united states provides a number of services for the public, such as helping people in need, teaching first aid, explaining water safety and artificial respiration and providing blood.
