Where does most of the worlds beef come from?

1. Brazil: Brazil is the largest beef producer globally, accounting for around 20% of the world's production.

2. United States: The US is the second-largest producer, contributing roughly 10% of global beef production.

3. China: China is rapidly increasing its beef production and is currently the third largest producer.

However, it's important to note that "most of the world's beef" can also refer to consumption rather than production. In terms of beef consumption, the top three are:

1. United States: The US consumes the most beef globally.

2. Brazil: Brazil has a large population and consumes a significant amount of beef.

3. China: China is also a major beef consumer, although their consumption has been increasing rapidly in recent years.

So, depending on what you mean by "most of the world's beef", the answer could be either Brazil (production) or the United States (consumption).
