There are many charitable organizations all over the world. Some of them are multinational while the others are local. One of the international charities is called The Chain of Hope. It does operations on children with heart diseases. In this organization, children from poor countries are treated free of charge. In my opinion, these organizations are more important than ever as we have more and more problems with diseases and food shortages, etc.
So the government and the individuals should play a role to keep them. People should give more money to these charities to let them help more people. Also, the government should facilitate their work.
