Bees struggle to find flowers because of air pollution
Warning: anecdote to follow. Data set: n=1. <i>Not</i> a peer-reviewed study. Just a completely irrelevant observation by a completely irrelevant HN poster.<p>But, yeah, I'm inclined to believe this. I live a few hundred meters (yards in Freedom Units<tm>) from two major highways.<p>Last year, at the tail end of the pandemic-induced lull in traffic, my flowers would attract groups of over 20 bees, easily, every day.<p>This year, with similar weather, pretty much the same flowers, and definitely the same location, it's a good day if I see 4 individual bees.<p>So, the answer 'air pollution' to the question 'what changed' seems at least likely?
