>co2 will cook the planet, industrial agriculture is poisoning the land, over fishing will collapse fish stocks.
The insect population is down a ridiculous amount where I live and also in neighboring germany.
I could link the study and such but honestly it's not like these things aren't backed up by my own experiences and those of my parents and grandparents.
I do find a lot lot less insects than I did when i was young. We no longer get much (if any) snow let alone the kneedeep stuff. It's harder to catch certain kinds of fish. The fishing boats where I used to visit every year go quite a bit further nowadays because those fish stocks have collapsed.
