A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
Reports of falling insect numbers around the world are not new. International reviews have estimated annual losses globally of between 1% and 2.5% of total biomass every year.
Widespread use of pesticides and fertilisers, light and chemical pollution, loss of habitat and the growth of industrial agriculture have all carved into their numbers. Often, these were deaths of proximity: insects are sensitive creatures, and any nearby source of pollution can send their populations crumbling.
But what Janzen and Hallwachs are witnessing is a part of a newer phenomenon: the catastrophic collapse of insect populations in supposedly protected regions of forest. “In the parts of Costa Rica that are heavily hit by pesticides, the insects are completely wiped out,” Hallwachs says.
Do you guys remember driving down the highway in the 90’s and having your car absolutely covered in the mangled corpses of insects? To the point where wiper fluid is called bug wash?
I don’t know if this is the same everywhere, but my car stays pretty clean these days.
Yes, cars had to wear bras
Nothing will meaningfully improve until the rich fear for their lives
I can’t remember where I saw it, but it was a quote from an elderly man who was sad that the vast flocks of birds he saw over the midwest as a child are no longer around. Literally just directly poisoning the earth. Madness.
the issue is, nobody cares about insects
Well I do… we need insects for a lot of reasons… but I fail to see what I can do for them. I’ve added a small water area, I don’t mow aggressively and let a portion of my garden absolutely wild… still I’m obviously having an abysmal and unnoticeable effect on the problem. So what now?
Two neighbors where over yesterday and I was pointing out the insect loss I’ve seen in just a few years. They both had their mouths open in shock. “Shalafi, I never thought of that.”
We leave the porch lights on 24x7. Used to get filthy with bugs and there were tree frogs and salamanders camping out all night. Now there are none of the above.
So… You know that leaving the porch lights on 24/7 is part of the light pollution problem that kills insects, right?
Half Life Tree confirmed
So… does at least Africa get to take a break from the tsetse fly?
