International trade has a major impact on U.S. agriculture. Exports are crucial, providing a market for a major share of crop production and a growing share of meat output. Over this period, the value of agricultural exports has exceeded the cost of agricultural imports, generating a trade surplus each year. Agriculture and its related industries (things like food sales and other industries that wouldn't exist or would be much smaller without agriculture) contribute $1.05 trillion to U.S. GDP, according to the latest data. That puts agriculture's contribution to the overall economy at about 6 percent. Firstly, trade affects the profile of risk factors for disease, trade may increase the risk of chronic disease, through the marketing of unhealthy products and behaviors (such as tobacco and “fast food”) and increased environmental degradation.
