环保小智

「环保小智」是一个「环保专业的云端知识库」，前身为环保手册，是科技环保理念下的一款创新产品，是我们广大热爱环保人士的贴心助手。 环保小智诞生伊始，只是希望能给环保人（狭义理解为环保从业人员）提供一个好用的文件查阅工具。但在产品使用的过程中，我们发现其实身边的企事业环保工作人员甚至是其他热爱环保的人士（加上狭义的环保人，构成了广义的环保人）也很需要环保知识库，但一直以来缺少一个好用的工具。 所以，带着这颗初心，我们觉得环保小智不应止步于服务环保人，应该致力于为每个热爱环保的人提供一款顺手的工具，让环保知识库得以开源、共享，让人们可以在「环保小智」中自如便捷地查阅环保知识，让再小的个体也可以拥有自己的环保知识库。
