Capybara
The individual capybara presents modest durability credentials, with natural lifespans of 8-10 years in the wild and up to 12 years in captivity. Their semi-aquatic lifestyle exposes them to various predators including jaguars, anacondas, and caimans, against which their primary defence mechanism involves running into water and hoping for the best.
However, the capybara's durability must be measured at the species level. Hydrochoerus hydrochaeris has maintained continuous operation across South American wetlands for approximately 10 million years, surviving ice ages, continental drift, and the arrival of humans with characteristic calm. The species demonstrates what ecologists term persistent adequacy: the capacity to simply continue existing through all circumstances.
Great Wall of China
The Great Wall's durability record demands nuanced analysis. The oldest sections, dating to the 7th century BCE, have largely crumbled to archaeological suggestion. The iconic Ming Dynasty segments, constructed between 1368 and 1644, remain standing through a combination of quality masonry and aggressive restoration programmes.
Approximately 30% of the original Wall has been lost to erosion, agriculture, and souvenir hunters who apparently believed removing stones would somehow enhance their holiday photographs. The remaining structure requires constant maintenance, with the Chinese government investing millions annually in preservation efforts. The Wall endures, but it does not endure effortlessly.
