slt à tous j'ai besoin de votre aide as a member of a philanthropic organisation you decided to write an ad to convince readers to donate blood merci d'avance

Tu peux simplement écrire « Just think about when you will need blood. If no one give blood for you you will die. Now think about the other people, it’s the same problem, as a member of our society you have to help the people around you as well as you can. Give your blood to save people. »
