What is the meaning of Salvatore Quasimodo's poem "La terra impareggiabile"?

Salvatore Quasimodo's collection of poems titled "La terra impareggiabile" means "The Unparalleled Land." It is a reflection on a fictional land, which he calls unparalleled and beautiful. But, because of tragedy and its separation as an island, it is full of isolation. The overarching theme of this work, and many others by Quasimodo, is an attempt to reconnect with others and, more importantly, start a dialogue about what is going on in the world.
There are many evils and terrible disasters that are happening, and, in his time, many people were simply overlooking them. Quasimodo wanted to look at them critically and analyze what we were doing to the world, particularly in the 1950s, in light of the Cold War and the tensions between nations.
