Primary Industry
Although Rio was once a place bustling with agriculture, it is now, like most major cities, rid of this primary industry. However, outside of Rio there is major agriculture in sugar cane, coffee, and soybeans. After being harvested these crops are taken to Rio where they are exported to other countries through the city's port. This brings in revenue for the city as most crops are taken here to be exported. However, Rio de Janeiro has most of its industry in services and manufacturing as it has developed past primary industry.
