Pizza
Few foods match pizza's democratic availability. From frozen supermarket offerings at two pounds to artisanal Neapolitan creations at thirty, pizza spans every economic bracket. Delivery infrastructure ensures arrival within thirty minutes to most urban addresses. Home preparation requires only basic ingredients and an oven. The pizza exists wherever humans congregate, from Antarctic research stations to International Space Station cargo deliveries. No geological event, economic status, or geographic location entirely prevents pizza access.
Volcano
Volcano accessibility presents considerable logistical challenges. Approximately 1,500 potentially active volcanoes dot Earth's surface, yet reaching most requires significant travel investment. Popular volcanic tourism destinations—Kilauea, Etna, Stromboli—demand international flights, hiking equipment, and often professional guides. Many active volcanoes exist in restricted zones. The experience of witnessing live volcanic activity remains a privilege enjoyed by perhaps one per cent of humanity.
