选项 A、people no longer value plants as a useful resource
B、botany is not recognized as a special branch of science
C、research is unable to keep up with’ the increasing numbers of plants

答案D
解析 问及人类对于植物的认识逐渐减少的原因。从第二段第一句“不幸的是，我们越变得工业化，我们和植物的直接接触就越少，我们的植物知识也就不那么清晰”可以看出，D项是正确的；另外文章最后一句也说明直接的接触消失了，人们关于植物的知识也就越来越少了。其他选项在原文中没有信息。
