Massive global insect decline could have ‘catastrophic’ environmental impact, study says

NZ, like many places globally, is slathered with hundreds of various poisons. No surprises that our insects are dying. Read Dr Meriel Watts’ book The Poisoning of New Zealand. Glyphosate is NZ’s fave.  As also is the insecticide 1080, dumped annually over our environment by the tonne.

Insect populations are declining precipitously worldwide due to pesticide use and other factors, with a potentially “catastrophic” effect on the planet, a study has warned.

More than 40% of insect species could become extinct in the next few decades, according to the “Worldwide decline of the entomofauna: A review of its drivers” report, published in the journal Biological Conservation.

Insect biomass is declining by a staggering 2.5% a year, a rate that indicates widespread extinctions within a century, the report found.
In addition to the 40% at risk of dying out, a third of species are endangered — numbers that could cause the collapse of the planet’s ecosystems with a devastating impact on life on Earth.
The report, co-authored by scientists from the universities of Sydney and Queensland and the China Academy of Agricultural Sciences, looked at dozens of existing reports on insect decline published over the past three decades, and examined the reasons behind the falling numbers to produce the alarming global picture.

Its lead author, Francisco Sanchez-Bayo, of the School of Life and Environmental Sciences at the University of Sydney, called the study the first truly global examination of the issue.
While the focus in the past has been on the decline in vertebrate animal biodiversity, this study stressed the importance of insect life on interconnected ecosystems and the food chain. Bugs make up around 70% of all animal species.

The repercussions of insect extinction would be “catastrophic to say the least,” according to the report, as insects have been at “the structural and functional base of many of the world’s ecosystems since their rise … almost 400 million years ago.”
Key causes of the decline included “habitat loss and conversion to intensive agriculture and urbanization,” pollution, particularly from pesticides and fertilizers, as well as biological factors, such as “pathogens and introduced species” and climate change.

While large numbers of specialist insects, which fill a specific ecological niche, and general insects were declining, a small group of adaptable insects were seeing their numbers rise — but nowhere near enough to arrest the decline, the report found.

Is it really a good idea Jacinda to drop dynamite into a NZ earthquake fault line?

Nigel Gray, a concerned NZ citizen, sent this recently to Prime Minister Jacinda Ardern,  (link to the article of concern is below … I share Nigel’s concern by the way)  —-

“Dear Jacinda,
This afternoon I read of GNS Science plans to drop dynamite into the earthquake faultline January 2019. I have seen in my lifetime NZ Government scientists or “experts” allow mass poisoning of NZers via mercury and lead in their tooth fillings, thalidomide drugs to pregnant women for morning sickness, electro-shocking of patients in our hospitals (now considered a form of torture by United Nations but still used all over New Zealand), glyphosate on our farmlands despite it being a known carcinogen and 1080 poisoning of our forests and waterways despite it being a toxic poison that is harming our ecosystem. You could of course reassure me that all these scientists and experts knew what they were doing too? I am well aware of your socialist links and your agenda to destroy the environment is very clear when we see your government agents dropping explosives on the fault line and poisoning our much loved forests.

I do not approve of my tax-payer dollars being spent on these programs by quasi-scientists, quasi-experts. Please cease and desist immediately.

Regards,

Nigel Gray ”

The Hikurangi subduction zone off NZ’s east coast, and its margins

 

“The Hikurangi Project is a multinational science investigation of the subduction zone beneath New Zealand’s North Island. Specially designed pressure sensors are in place to detect uplift or subsidence of the sea floor.

Scientists researching New Zealand’s largest fault line are preparing for an explosive start to the new year.

In Napier on Wednesday night, researchers from GNS Science and NIWA discussed their latest findings and the future of their ongoing monitoring of the Hikurangi subduction zone off the east coast.

Dr Dan Bassett of GNS Science said 900 seismometers would be deployed between Gisborne and Whakatāne as part of the next phase of the organisation’s SHIRE project.

Scientists would then detonate five dynamite shots within shallow boreholes to generate seismic energy.

When Hikurangi subduction zone megathrust triggers tsunami ‘think Japan 2011’

Scientists thought the southern end of the country’s largest fault was dormant before the Kaikōura earthquake because it had not moved in recorded history.

And while some still debate how big a role the southern Hikurangi subduction zone played in the 7.8-magnitude earthquake, they agree it is now moving.

The Hikurangi subduction zone runs offshore from the east of Gisborne to the top of the south and would be capable of a devastating earthquake and tsunami.
