text: My personal view is because they are not as healthy for people or for the enviornment...the reason why they are not good for the environment is because the best produce to buy is that grown closest to home. Less gas is used and local farmers get the money as opposed to large corporations who are trucking it across the U.S. in refgridgerated trucks. I think there are lots of negative effects that would be hard to go into here but you should try looking up the positive effects of organic and locally grown conventional produce to get you started thinking. Does any of that help?
