“Green” Products Are Sending Up a Red Flag
Not all products are as environmentally friendly as their labels want you to believe by Joanna Wuertz
These days everyone is trying to do their part to help the environment. One of the easiest ways is simply to buy products that are labeled “eco-friendly.” Choose fruits and vegetables that are organic. Select appliances that are energy-efficient. Avoid items made with synthetic materials. But going green may be harder than it looks – those product labels can be misleading.
通常是用raise a red flag，亮起紅燈之意，
send up是升起；發射，因此在這裡指所謂的綠色產品的標籤，是需要警戒注意的。參考資料： 自己＆Internet
