Total mass of insects falling
jeudi 18 mai 2017 à 02:00Since 1989 the total mass of insects in Germany has fallen by 80%. And it's not just in Germany — this is an example of a widespread tendency.
I think the writer is obtuse about extinction. Concern about extinction is not a matter of "fetishizing" the last few individuals of the species. The species is different from its members, and the loss of a species is different from the death of any number of members of that species.
If a given species of frog has a million members, the death of a specific hundred of them would not concern me much. If those hundred were the only ones left, their death would still not concern me much; but it would mean the extinction of the species, and I would consider that a real loss.
An 80% decrease in insect biomass is a big ecological change, and I think we had better find out soon what we did to cause it.
