Not just the bees, all bugs in North America have seen a 75% die off in the last 20 years.
Big shocker that songbirds, which eat those bugs, have also seen a massive die off.
Despite those deniers that still blame housecats, the true culprit is almost certainly pollution and pesticides.
Both things can be true. They aren't mutually exclusive.
Also we have less pollution and pesticide use than we did in the 60s and 70s. Why is it just becoming a problem now?
less pollution? that cannot possibly be true. according to dr google 1970s world population was 3.7b, now we're more than double that
I’m the US, the EPA was created in the 1970’s. We definitely have less pollution (of certain types) today than we did in the past. Some notable examples of how disgustingly polluted American skies and waterways were in the past:
The skies of Pittsburgh, PA
the Cuyahoga River fire
Coal Production has also been declining
And then of course less visible examples like the Montreal Protocol stopping corporations from depleting the ozone layer.
My point is in terms of greenhouse gas production we are much higher than in the 60’s and 70’s, but we have massively improved in a lot of areas. Of course there is still room to improve.
I bet that while we have less general pollution and less dumping trash in the environment kinda things, we have developed much more potent insecticides. And if those insecticides do not degrade within a few weeks they will accumulate in the earth and the water.
Edit: Wikipedia about one type of modern pesticides: https://en.wikipedia.org/wiki/Neonicotinoid
Yeah, pretty sure your lawn has almost nothing to do with insects vanishing. It's much more likely the insane amounts of highly potent pesticides we put directly into our food chain. Those pesticides obviously aren't classified as pollution so we aren't polluting, we're killing the environment on purpose.
Btw. The development and use of neonicotines corelate quiet nicely with the drop in the insects population.
To put that in perspective, let's say I drink water contaminated with chemicals for decades. Then, "suddenly", me and half the people i know are sick with cancer and various side effects decades later...
That's how environmental toxins work. They accumulate throughout the water cycle and through the food web, and if its less than acute (short term) in effect it statistically hurts a population, such as lowering reproduction or creating birth defects that lower the fitness. Then, once concentrations pass LD thresholds (lethal dose, meaning LD50 will kill half of the individuals of a species on average, LD10 would kill 1 in 10) you start getting mass die offs
Every water table, all of the soil, every living being is riddled with non-naturally occurring substances. Even though we released more damaging toxins in the 80s, the rate of pollution doesn't matter - the concentration in various parts of the ecosystem is what matters, and that's a slow process
House cats are making it worse too
Both things are true
Housecats were actually keeping the bird population healthy for decades by eliminating the weak. Of course now that habitat destruction and toxins made entire populations weak it is a problem.
But removing housecats to solve it is akin to drinking out of paper straws to solve plastic pollution. It helps, but it doesn't do anything substantial.
Why would you say that? Hawks and owls were the “natural” predator of North American song birds and I’ve seen plenty of raptors in my large US city. Not like bobcats are suffering population-wise in urban areas.
Outside cat / feral cats have had massive negative impacts on bird and small mammal populations. Particularly in areas where they fill an ecological niche that the wildlife hasn't adapted to due to none of the local fauna being in that niche. Hawaii and Australia in particular have this problem.
Those are indeed special situations where cats are basically an invasive species.
Here in Europe the correlation between cats and bird population is not so strong. While destruction of habitat and the crash in insect numbers are the big culprits.
I'd say and cars just think about how many bug splatters you see on an average decent trip on the highway now multiply that by the millions of cars on the road daily. It's not the root cause but it certainly didn't help
Oh certainly can't help. But we know that the pesticides and herbicides have carryon effects to unintended species. Ones that the parent companies that invented them didn't report on because they don't kill those species. Ones that don't necessarily kill them, but lead to things like the white nose fungus running amock in bats, or lead to Colony Collapse Disorder or other infections in bee colonies.
Why would white nose fungus and pesticides be linked in the slightest? The issue with that is tourists who don’t want to admit they’ve been driving from national park to national park visiting each cave along the way without sanitizing anything. Same reason Zebra Mussels are spreading so rapidly. Just like people blaming 5G for COVID: It’s easier to externalize blame rather that come to terms with the, frankly, minuscule amount of spores that are needed to destroy the entire roosting colony.
My car used to look terrible after a drive to the local wilderness area, now I'll be lucky to see one smack my window per trip.
Im gonna dig a pit in my backyard and make a pond. Its gonna be a lot of work but it will all be worth it when i sit out on my patio in the morning sipping coffee to the sound croaking frogs, buzzing bugs, and chirping birds.
You will want to be careful doing that. It needs to be big enough to have differential temperature so the water moves, therefore aerating it. Without air in the water nothing but mosquitos can live or breed in it. Also, depending on the soil and whether you are above the water line, you may not be able to keep enough water in it between rainfalls.
I'm sure you can look up how to do one properly, I just want to to be aware it's not as simple as dig a hole and fill it with water, because that will do more damage than good.
Of course I've been doing a lot of research dont worry. And also I'll be using a pond liner
Same in Europe
