Such a sad story. Father and son out on a fun adventure and that happens.
I have a couple of favorite hiking spots on the San Francisco Peninsula where signs are posted at one location on each trail “Caution: Bees / Yellowjackets.” I keep wondering “Why don’t they eradicate them instead of putting up a sign?” It’s utter insanity to run the risk of somebody dying on those trails because they don’t want to kill BUGS.
We eradicated the Murder Hornets in the US - I think France has them now as well - another downside to globalization
They put the signs up because of liability. There is no way for them to know where every nest is, some have nests in the ground. Neighbor pulled up a bush this fall to get rid of it and there was a huge nest in its root system.
Bees and hornets pollinate flowers. Without them no fruit trees, no nut trees, no flowers. The world is a giant evo system.
