Insect Apocalypse

Insects Are Dying En Masse, Risking ‘Catastrophic’ Collapse Of Earth’s Ecosystems

The insect apocalypse is indeed upon us, according to the first global scientific review of insect population decline.
 
There have been warning signs for years about plummeting insect populations worldwide, but the extent of the potentially “catastrophic” crisis had not been well-understood — until now. 

The first global scientific review of insect population decline was published this week in the journal Biological Conservation and the findings are “shocking,” its authors said.

More than 40 percent of insect species are dwindling globally and a third of species are endangered, concluded the peer-reviewed study, which analyzed 73 historical reports on insect population declines.

Chillingly, the total mass of insects is falling by 2.5 percent annually, the review’s authors said. If the decline continues at this rate, insects could be wiped off the face of the Earth within a century.

“It is very rapid. In 10 years you will have a quarter less, in 50 years only half left and in 100 years you will have none,” study co-author Francisco Sánchez-Bayo, an environmental biologist at the University of Sydney, Australia, told The Guardian.

“If insect species losses cannot be halted, this will have catastrophic consequences for both the planet’s ecosystems and for the survival of mankind,” Sánchez-Bayo added.

Scientists have warned that a human-caused sixth mass extinction is now underway on Earth. Vertebrate species, both on land and under the sea, are threatened at a global scale because of human activities.

But according to the new review, the proportion of insects in decline is currently twice as high as that of vertebrates and the insect extinction rate is eight times faster than that of mammals, birds and reptiles.

 

Insects play a profoundly important role in Earth’s ecosystems. They are a food source for many animals, are critical pollinators and recycle nutrients back into the soil.

In a November New York Times report about a possible “insect apocalypse,” scientists were asked to imagine a world with no insects. 

They found “words like chaos, collapse, Armageddon,” the Times wrote. ”[One entomologist] describes a flowerless world with silent forests, a world of dung and old leaves and rotting carcasses accumulating in cities and roadsides, a world of ‘collapse or decay and erosion and loss that would spread through ecosystems.’”

According to the new scientific review, habitat loss because of intensive agriculture is the top driver of insect population declines. The heavy use of pesticides, climate change and invasive species were also pinpointed as significant causes.

“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades,” the review’s co-authors wrote. “The repercussions this will have for the planet’s ecosystems are catastrophic to say the least.”

I have issues with these claims of " insects could be wiped off the face of the Earth."  That's not how this works.  Long before that point is reached, there would be a global ecological catastrophe.  And it wouldn't take anywhere near that much to destroy modern just-in-time civilization.  The real point is, we'll go before they do.  Our corpses will help their population recover.

Besides which, a lot of our current intensive farming will be unviable sooner than that due to climate change, which should make more space for insects to return. I think they did quite well last time the world was that hot.

The BBC's report was a bit better, and emphasized that the likely scenario is an  INCREASE in pest insects and decrease in the nice, useful ones.

Insectless crop famine would collapse civilization and CO2 levels would begin falling with few cars, and trees taking over the suburbs.

It happened before with the collapse of Native American civilization. So many trees took over that CO2 levels dropped and the world went through the little ice age.

I have no idea how to save the insects. Seems like it is the kind of thing that is like turning an oil tanker or the Titanic around. By the time we could implement the changes that would reverse the trend it would be too late for civilization to not go through a very hard time.

Butterflies, bees and native species are suffering from a massive die off. The majority of scientists predict a global apocalypse by 2100. OTOH, 2050 looks to be a mark of planetary degredation. We're already seeing massive storms, flooding, drought, and other destructive events. It's likely that our descendants will live in a world that may be very different.

And yet we can do so much. Maybe it's a question of will.

Yes. We can mitigate the destruction but it may require overturning the power structure.

How soon and how much is a lot?

Currently the world is producing bumper, record-breaking quantities of commercial crops at the same time 'scientists' have been trying to convince us temperatures have gone up (or down since 1998).

And thanks to advances in the commercial farming sector, this bumper crop of food is being produced primarily on 20% less land using far less pesticides overall. 

But if the 'scientific' alarmism proves correct (which is very doubtful), commercial farmers will simply move marginally North or South (depending on your hemisphere and the atmospherics at play) in order to grow commercial food at quantities to provide a continuing abundance of excess foods to wasteful non-appreciative Westerners (excluding China).

Hilariously, using current alarmist 'climate data', it's estimated Scotland will be able to grow hard wheat by the year 5,119.

We can actually do a lot to help insects without having to wait for that. We can stop growing lawns, plant exclusively native plants, and build insect hotels. These are all a huge help to insects.

Lise - you've already incorrectly claimed the people of the Carteret Islands were being evacuated as a result of sea level rise caused by 'climate change', so any shred of credibility you may have left in the so-called 'climate change' space is up for scrutiny, no matter how much 'study' you've allegedly undertaken.

From comments you've made in previous threads about pesticides/herbicides/GMOs and modern intensive farming techniques, it was clear you knew less about those issues than so-called 'climate change' issues that you said caused the evacuation of people from an island which never occurred.

You can stick your head in the sand by standing on your pious 'beliefs' or you can indicate where any farming has ceased due to 'climate change', or where it is likely to initially cease based on so-called 'climate' modelling.

Dealing with insects is easy.  The Monarchs came back: panic over. I wish there was a pesticide for panic merchants.

YOU are incorrect about the Carteret islands. Your brain can't or won't accommodate anything that's too complex. We've already established this.

No, I'm correct and you couldn't prove otherwise back then.

What you said about the evacuation of the Carteret Islands was wrong. You need to prove why you think you're right.

Don't be shy: lemme have it.  But you can't, so you won't.  Ah, that's a shame.

Yeah, thought so. You've got nothing and haven't got it in yourself to say you were wrong.

Just provide ONE link to some authoritative site that proves you're contention right. It's not that big an ask, or hard.

You would do it if you could, in a heartbeat.

Alternatively, I will forever remain disappointed in you.

You're projecting. You're the one maintaining your denial as we suffer through record heat waves, record floods, record fires. You're becoming increasingly ridiculous.

The Carteret islanders are considered the first population being evacuated.
