Mark Zuckerberg is raising cattle while reportedly building a huge underground bunker in Hawaii — the cows will drink beer to make ‘the highest quality beef in the world.’ What’s he up to?

Meta CEO Mark Zuckerberg has been making waves recently regarding his expansive property on the Hawaiian island of Kauai.

Zuckerberg has been constructing a 1,400-acre compound — featuring a 5,000-square-foot underground shelter, "blast-resistant door" and "escape hatch" — across his property, known as Ko'olau Ranch, according to an investigation by Wired. The compound will be equipped with "its own energy and food supplies."

This is not your usual bug out spot. The cost of the project, including land purchases and extensive development, exceeds $270 million, according to Wired.

But Zuckerberg's activities on Ko’olau Ranch extend far beyond mere refuge. In a recent Instagram post, the billionaire divulged his newest venture: cattle farming.

“Started raising cattle at Ko'olau Ranch on Kauai, and my goal is to create some of the highest-quality beef in the world,” Zuckerberg announced. “The cattle are wagyu and angus, and they'll grow up eating macadamia meal and drinking beer that we grow and produce here on the ranch.”

Zuckerberg is determined to keep the entire process “local and vertically integrated.” His family has been assisting with the operations.

“Each cow eats 5,000-10,000 pounds of food each year, so that's a lot of acres of macadamia trees. My daughters help plant the mac trees and take care of our different animals,” he shared.

“Of all my projects, this is the most delicious.”
