Questa tabella prevederebbe un aumento della popolazione fino a oltre 8 miliardi, ma la produzione di cereali ha raggiunto il suo massimo in questi anni e basta appena per circa 6 miliardi e 500 milioni di persone.

Tant'è che il prezzo dei cereali è raddoppiato.

Siamo già in 6 miliardi e 800 milioni e infatti il cibo non basta più per tutti.

La domanda è superiore all'offerta.

E' forse prevedibile che il limite massimo della popolazione sarà sui 7 miliardi e poi la crescita si fermerà per mancanza di cibo?
