    “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.

    red flag有提起警示,或是要人注意的意思,

    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。

    to send Up a Red Flag指「發出異樣或危險訊號,而須要提高警覺予以關注」Red flag = a warning signal; something that demands attention. = suggests that something is wrong It means to alert someone to a danger.
