随着全球气候异常现象不断升级，各国人民的环保意识也在提升。低碳生活、低碳经济正在慢慢深入人心，而提倡人们多多选用本地出产食品的“土食者(locavore)”们也越来越多了。

　　A locavore is someone who eats food grown or produced locally or within a certain radius such as 50, 100, or 150 miles (240 km). The locavore movement encourages consumers to buy from farmers’ markets or even to produce their own food, with some arguing that fresh, local products are more nutritious and taste better. Locally grown food is an environmentally friendly means of obtaining food, since supermarkets that import their food use more fossil fuels and non-renewable resources。

　　“土食者”(也称“本土膳食主义者”)指那些热衷于食用本地或住所周边50到150英里范围内出产食物的人。这种“土食活动”鼓励消费者到农贸市场去购买食物，或者干脆自给自足，因为他们认为当地产的新鲜产品更有营养、口感也更好一些。本地出产的食物是比较环保的，因为超市从外地进购这些产品的话会耗费更多燃料和不可再生资源。

　　"Locavore" was coined by Jessica Prentice from the San Francisco Bay Area on the occasion of the 2005 World Environment Day to describe and promote the practice of eating a diet consisting of food harvested from within an area most commonly bound by a 100-mile (160 km) radius. "Localvore" is sometimes also used。

　　“土食者”这个理念是旧金山湾区的杰西卡•普兰提斯在2005年世界环境日提出来的，提倡食用居所周边100英里范围内出产的食物。有时在英文中也会写做localvore。
