Warning of 'ecological Armageddon' after dramatic plunge in insect numbers

The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists.

Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.

The new data was gathered in nature reserves across Germany but has implications for all landscapes dominated by agriculture, the researchers said.

The cause of the huge decline is as yet unclear, although the destruction of wild areas and widespread use of pesticides are the most likely factors and climate change may play a role. The scientists were able to rule out weather and changes to landscape in the reserves as causes, but data on pesticide levels has not been collected.

We spray pesticides everywhere. Just what we do on our lawns is insane. Walk into any Home Depot or Lowe’s. There is a huge aisle stacked with products that contain both herbicides and pesticides.

That fertilizer with pre-emergent in it? Have you ever stopped to think what else it kills? Lizards? Nematodes? Mayflies? What else?

We spray chemicals everywhere and really we have little understanding of the systemic effects. We fight the good fight against mosquitoes. But what if we kill them all? What eats mosquitoes? Surely they will then starve.

We seem to think that somehow we stand apart from the ecosystem. But we are part of it and depend on it to survive.

At some point we will kill too many of the little creatures and then creatures that eat them will starve and then this will ripple up through the system until the apex predator can no longer survive.

And that apex predator is us. As Pogo once said, “I has met the enemy and he is us.”

Fruit flies are increasing across the US though! I have a severe allergic reaction if they come close to me and my sheets have been covered in blood for 5 months now! I look like I have chicken pox even though it isn't from actual bites (if they touch your skin your body can react like it has been bitten).

And CO2 levels are already over 400 ppm and rising fast as we keep burning fossil fuels.

In a million years, new species will evolve from the survivors to fill the empty niches we're creating. Of course, we won't be there to see it, since we'll have driven ourselves to extinction long before then.

Soon, we'll just be a layer of geological strata for alien archeologists to puzzle over.

The tons and tons of plastic waste, radioactive waste, chemical contamination and toxins need to degrade, which will take a long, long time.

What we poisoned ourselves with likely will become a resource for some organism if we don't succeed at killing all life. Some type of bacteria that can digest plastics will start reducing polymers to monomers. It will take multiple millions of years if there is to ever be "intelligent" life after we exterminate ourselves.

At least our requirements for a livable ecosystem keep some of us from completely trashing the planet.

Would a society of AI give a damn if their actions sterilized the planet entirely?
