Each week one question, four expert witnesses, and an answer.
It's early May in the town of Ubaraba in southeast Brazil,
in the heart of the country's agricultural interior.
And 400,000 people and nearly 3,000 cattle have gathered for a vibrant celebration of Brazil's cowboy culture.
There are cattle in corals, stands selling burgers,
and families walking around admiring the livestock.
And they're here for Expo Zebu, an annual fair dedicated to the Zebu Super Cow,
a genetically hyper-advanced breed of cattle that is prized for its beef and which now dominates Brazil's meat production.
Brazil exported 2.9 million tons of beef in 2024,
most of that from Zebu herds, and demand is still rising.
So for the inquiry this week, we're asking Can Brazil's supercows feed the world?
The zebu animals are huge.
