Cassandra has moved. Ugo Bardi publishes now on a new site called "The Seneca Effect."

For three minutes of relax, watch this video showing some of the things we are trying so hard to destroy (by David Bayliss).


  1. Per il piacere dei lettori di Cassandra's legacy, in sintonia con il post di Ugo Bardi, una rassegna di fiori e insetti italiani, molti dei quali del Monte Morello, presso Firenze. Piccola natura intorno a noi:

  2. Depressing, not relaxing.

  3. Hi Ugo,

    after the relax, back to reality. Your colleague, professor of physical chemistry, the youngest in UK (at 34y), Chris Rhodes, writes about peak phosphorus, finishing with this:

    There is a Hubbert-type analysis of human population growth which indicates that rather than rising to the putative “9 billion by 2050″ scenario, it will instead peak around the year 2025 at 7.3 billion, and then fall. It is probably significant too that that population growth curve fits very closely both with that for world phosphate production and another for world oil production. It seems to me highly indicative that it is the decline in resources that will underpin our decline in numbers as is true of any species: from a colony of human beings growing on the Earth, to a colony of bacteria growing on agar nutrient in a Petri-dish.

    aaaah, nobody likes the Petri dish analogy, but everybody behaves like that... Alex



Ugo Bardi is a member of the Club of Rome, faculty member of the University of Florence, and the author of "Extracted" (Chelsea Green 2014), "The Seneca Effect" (Springer 2017), and Before the Collapse (Springer 2019)
