I am very interested in this meeting. As the President said, we have subjects that are really very important, like the question of the new forms of energy, the question of food security, the question of water, and we have been assured the presence of the Pope. These are the most important questions today, also contained in the last document of the Pope, the Encyclical Laudato si’, which asks for new forms of energy and also the problem of food, and this subject is also in relation and in synergy with the new Sustainable Development Goals of the United Nations. All these things mean that our meeting has a special intensity also because we have, for the first time in a Plenary Session, invited specialists that are not our Academicians. I hope we can really have in the end an important contribution to the development of sciences for the sustainable development of the world.
