At the peak of global tobacco production, there were 20 million rural Chinese households producing tobacco on 2.1 million hectares of land. [12] The vast majority of tobacco production is intended for the national market. While it is the major crop for millions of Chinese farmers, growing tobacco is not as profitable as cotton or sugar cane.
In the period of 1619 to 1629, the average tobacco farmer was expected to produce 712 pounds of tobacco in a year. By the period of 1680 to 1699, the output per worker was 1,710 pounds of tobacco in a year. [6] These increases in productivity were brought about primarily from relocation and better farming techniques.
The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre.. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. [1]
Heavily mechanized, U.S. agriculture has a high yield relative to other countries. As of 2004: [20] Corn for grain, average of 160.4 bushels harvested per acre (10.07 t/ha) Soybean for beans, average of 42.5 bushels harvested per acre (2.86 t/ha) Wheat, average of 43.2 bushels harvested per acre (2.91 t/ha, was 44.2 bu/ac or 2.97 t/ha in 2003)
Cigarette smoking alone has cost the United States $96 billion in direct medical expenses and $97 billion in lost productivity per year, or an average of $4,260 per adult smoker. In 1964 the Surgeon General of the United States published its landmark report, Smoking and Health, which identified smoking as the cause of many health problems. [8]
The tobacco industry comprises those persons and companies who are engaged in the growth, preparation for sale, shipment, advertisement, and distribution of tobacco and tobacco-related products. [1] It is a global industry; tobacco can grow in any warm, moist environment, which means it can be farmed on all continents except Antarctica .
