But surely that does not mean environmentalists concerned about uncontrolled industrial growth are anti-science, as an essay in US News & World Report last May seemed to suggest.

我不明白这个部分 as an essay in US News & World Report last May seemed to suggest.  这个 as 是什么作用，这个句子潜在含义是什么？

【翻译】但肯定的是，这并非说对无度的工业发展表示关切的环境专家们是反科学的，正如去年5月在《美国新闻和世界报导》上的一篇文章所暗示的那样。

【分析】as an essay in US News & World Report last May seemed to suggest，是as 引导的非限制性定语从句。

【语法知识】as引导的从句表示说话人的看法、态度、解释或评论。

    as用来引导非限制性定语从句，其先行词是整个主句，它在句中作主语、宾语。此时as仍具有“正如，像，由……可知”等意思，有时可不必译出。它引导的从句可以位于主句前，也可以位于主句后，还可以位于主句中间。常跟这些表示“看法、态度、评论”的动词 see, know, hear, suggest, remember, say, tell, show, expect, guess 等连用，这类动词与as 连用几乎成了一种固定搭配。

    as 用于非限制性定语从句，其先行词是整个主句，它在句中作主语、宾语。它引导的从句可以位于主句前，也可以位于主句后，还可以位于主句中间。
