环保英文怎么拼

"Environmentally friendly or environment-friendly, (also referred to as eco-friendly, nature-friendly, and green) are sustainability and marketing terms referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment."----from wikipedia所以两种说法都对，但是environment-friendly 中间有连字符。

环保environmental protection

绿色环保：environmental-friendly(一个词，是adj.形容词)；也可直译为green(作adj.形容词用)。例如：environmental-friendly agriculture 生态农业enjoy an Environmental-friendly Christmas 过一个环保圣诞但是如果一句话中既有green又有environmental-friendly时，如下句例，green的意思就只能是其本意“绿色(地)”，而非“绿色环保(地)”：Select green-decorated materials to do indoor environmental-friendly decoration 选绿色装修材料，做环保室内装修而a green material翻译成“一种(新型)绿色材料”即可。另外，如果说某产品是假环保，就称其是一种“洗绿”行为：greenwashing(名词n.,“绿色粉饰，刷绿，洗绿”)。该词由whitewash(动词v.,“粉饰”)一词类推构成。详见下面给出的链接。
