We haven't seen a quarter of known bee species since the 1990s
This article published by National Geographic highlights the findings of a study published in the journal One Earth which reveals that in recent decades, the number of bee species reported in the wild has declined globally - roughly a 25% reduction of spotted species between 2006 - 2015 on all continents except Australia. The article also discusses the causes of the decline in bee diversity, as well as the importance of contributions by citizen scientists to help fill research knowledge gaps.
