Can we talk about important issues such as sustainability and the future of the Planet and do it in an immediate, fun, sunny but authoritative way at the same time? Between World Water Day and Earth Day, Rai1 calls together artists and scientists for a special evening that reminds us that the problems of the planet do not go on standby. An evening in which the protagonists will be sustainability and issues relating to the environment and the protection of our planet. With this common thread clearly highlighted, the program will be a variety that will give space to contents conveyed with authority, but also with irony, fun and lightness, without neglecting the musical component which is indispensable with the presence of a conductor who is also a much loved musician.
