People of Cambodia are very closely tied to their land. More than three-fourths of the workforce is employed in agriculture. Rice is the main crop, but some export crops are pepper, cassava, corn, rubber, sugarcane, and soybeans.
Fruit is also an important subsistence crop.
Livestock includes water buffaloes, cattle, and pigs. Most of Cambodia's fish comes from the Tonle Sap Lake. Illegal logging is still a problem, and charcoal kilns dot the countryside near Sihanoukville. Of concern is human and animal waste pollution in Tonle Sap Lake, one of the world's richest sources of freshwater fish. Hydroelectric power has potential, but could cause ecological problems.
