Here’s a crazy thing no one talks about; Bugs. Dad taught me to clean the car’s windshield at every gas stop. Ya know, use the squeegee at the station? That was normal car maintenance. We’d often stop just for that purpose. Bug guts everywhere.

This. When I was a kid during the 90s, cars were covered in bugs during summer. Today there are bugs on windshields too, but compared to back then it's maybe only 10% of them. What also comes with the decliine in the insect population is a decline in the population of birds, because there are lesser and lesser natural habitats and food sources.

I am from Europe. What I also noticed is that, when you find insects or spiders and such, many of them are invasive and originally located in southern Europe. But each year they appear farther north, probably because of cilmate change.

For instance, the spider Zoropsis spinimana is a relatively new species in our region, and it's venomous*. Due to it's similarity it can be confused with Tegenaria domestica which is harmless to humans.

Also, with a warmer climate there are more ticks which are prone to spread diseases harmful to humans.

• Addition: the bite of Zoropsis spinimana is compareable to a wasp sting and is only dangerous to people who have allergies against the venom.
