1Is organic food worth the higher price? It’s the classic grocery store dilemma. On the one hand, your family dinner
2table deserves only the best. On the other hand, your wallet can only stretch so far.
3Whether or not to buy organic is a personal decision, said Mike von Massow, professor of Food Agriculture.
4Science won’t give a clear-cut answer to the question of whether organic food is “better.” There are often trade-offs
5(权衡) and answers become less definitive depending on the product under consideration.
6One thing is definitive: Organic and conventionally grown food are equally nutritious. From a nutrition point of view,
7there is no difference between organic and traditionally grown products.
8Organic products don’t necessarily have fewer pesticides (杀虫剂)—in fact, they may have more. There is also no big
9difference between organic and non-organic products from a food-safety perspective. Even organic growers use pesticides.
10Testing shows little if any pesticide remains on conventionally grown products.
11In fact, organic farmers often use larger quantities of pesticide because they can only use the natural variety of
12insect-killers. Chemical pesticides generally kill a much wider range of pests (害虫) than any single natural pesticide.
13The use of animal waste in organic agriculture can also be a factor in the spread of bacteria like E. coli and
14salmonella. Over the past 10 years, Canada has seen more food-safety recalls for organic products, proportionally, than
15for conventional products.
16On the whole, organic agriculture may have a smaller environmental footprint. That’s mostly because the risk of
17groundwater contamination from organic farming is lower. Organic farmers never used neonics, the controversial
18pesticides that have been linked to shrinking bee populations worldwide.
19Traditional agriculture has been making “dramatic improvements” to reduce its impact on the environment.
20It isn’t a black-and-white picture, though.
21Organic farming is much less efficient when it comes to land use, although yields vary considerably depending on the
22crop.
23On the other hand, advocates of organic farming argue yields and efficiency could be significantly improved if the food
24industry devoted as much research and money to organic farming as it does conventional agriculture.
