Every five years, the government tries to tell Americans what to put in their bellies. Eat more vegetables. Dial back the fats. It’s all based on the best available science for leading a healthy life. But the best available science also has a lot to say about what those food choices do to the environment, and some researchers are annoyed that new dietary recommendations of the USDA (United States Department of Agriculture) released yesterday seem to utterly ignore that fact.
Broadly, the 2016- 2020 dietary recommendations aim for balance: More vegetables, leaner meats and far less sugar.
But Americans consume more calories per capita than almost any other country in the world. So the things Americans eat have a huge impact on climate change. Soil tilling releases carbon dioxide, and delivery vehicles emit exhaust. The government’s dietary guidelines could have done a lot to lower that climate cost. Not just because of their position of authority: The guidelines drive billions of dollars of food production through federal programs like school lunches and nutrition assistance for the needy.
On its own, plant and animal agriculture contributes 9 percent of all the country’s greenhouse gas emissions. That’s not counting the fuel burned in transportation, processing, refrigeration, and other waypoints between farm and belly. Red meats are among the biggest and most notorious emitters, but trucking a salad from California to Minnesota in January also carries a significant burden. And greenhouse gas emissions aren’t the whole story. Food production is the largest user of fresh water, largest contributor to the loss of biodiversity, and a major contributor to using up natural resources.
All of these points and more showed up in the Dietary Guidelines Advisory Committee’s scientific report, released last February. Miriam Nelson chaired the subcommittee in charge of sustainability for the report, and is disappointed that eating less meat and buying local food aren’t in the final product. "Especially if you consider that eating less meat, especially red and processed, has health benefits," she says.
So what happened? The official response is that sustainability falls too far outside the guidelines’ official scope, which is to provide "nutritional and dietary information."
Possibly the agencies in charge of drafting the decisions are too close to the industries they are supposed to regulate. On one hand, the USDA is compiling dietary advice. On the other, their clients are US agriculture companies.
The line about keeping the guidelines’ scope to nutrition and diet doesn’t ring quite right with researchers. David Wallinga, for example, says, "In previous guidelines, they’ve always been concerned with things like food security—which is presumably the mission of the USDA. You absolutely need to be worried about climate impacts and future sustainability if you want secure food in the future."
What may account for the neglect of sustainability in the USDA’s Dietary Guidelines according to the author?
选项
A、Its exclusive concern with Americans’ food safety.
B、Its sole responsibility for providing dietary advice.
C、Its close ties with the agriculture companies.
D、Its alleged failure to regulate the industries.
答案
C
解析
推理判断题。定位句提到,官方认为,可持续性远远超出了指南的官方范围,而作者在随后的第七段分析指南不涵盖可持续性的原因在于,草拟指南的机构与他们应该监管的行业过于接近。换言之,负责饮食建议的美国农业部的客户就是美国农业公司,故C)为正确答案。
