Santi Palacios shares with the TEDxPatras audience his view on what is, in broad strokes, the greatest of global necessities; people acting to achieve good on their own free will. The Madrid- born photojournalist feels strongly that the values of education and knowledge are necessary tools to achieve that goal- and also clearly states that, in his regard, photojournalism- like other disciplines as well- has an important role to play. Publishing images does indeed generate re-actions and, therefore, can prove to be the cause of short and long- term changes alike. Santi Palacios gets on the TEDxPatras stage, explaining why photojournalism does work to achieve changes- and expressing the hope that those changes will prove to be leading us towards a brighter future.
