Final answer:
Brazil and Vietnam are the first two largest green coffee producers in the world, with Brazil maintaining a significant lead in global coffee production.
Step-by-step explanation:
The first two largest green coffee producers in the world are Brazil and Vietnam. Brazil's substantial agricultural growth over the past few decades has ensured its position as a major exporter of agricultural products, including coffee. While coffee accounts for only about five percent of Brazil's annual exports, the country is recognized for its extensive coffee production in the Brazilian Highlands.
Meanwhile, Vietnam has emerged as a powerhouse in coffee production, surpassing traditional coffee giants like Colombia. Coffee production is crucial in tropical climates, and both Brazil and Vietnam have capitalized on their favorable geographic and climatic conditions to dominate the global coffee market.
