Farming, mining, and fishing are examples of primary production. This means that they involve the extraction or cultivation of raw materials directly from natural resources. In farming, crops are grown and animals are raised for food and other agricultural products. In mining, minerals and other valuable resources are extracted from the earth. And in fishing, fish and other seafood are harvested from the oceans, rivers, and other bodies of water. These primary production activities are the foundation of many economies, as they provide the raw materials that are used in secondary and tertiary production processes to create finished goods and services.
