3/4 of flying insects gone

Please place treatment free research here. There's a lot of research spread around the Internet that is related to treatment free beekeeping. This forum is an effort to try and consolidate some of this, especially new research as it becomes available.

Thanks for posting that link, moebees.

This results from the planting of energy plants and the rising of cattle numbers in Germany.

Agricultural areas are becoming more and more green deserts, always harvested, no flowers, no bird´s nests and rural areas we have not many.

I just listened to a podcast with a similar topic. Entomologist Doug Tallamy PhD discusses the loss of native plants and how that affects the insect population.

I enjoyed the the podcast and ended up watching the television episode also.

Re-posting essentially the same article (but some details are complementary - hence still posting)

Part of the Germany's problem (likely, the major part) is efficient implementation of centrally managed agricultural industrialization.

I am becoming more and more anti-centralization (ironically, as I still do favor some centralized approaches - health care, what not).
The less centralization means less efficient implementation of potentially bad programs.
Even if we observe some bad local programs, at least they remain local.

I don't know how else protect the remaining eco-system fragments outside of obstruction.
I do know that obstructing human activity in any way usually means good news for the eco-systems (and, actually, benefits the humans in the log run).

Here is on good example - Chernobyl (very, very ironic example):

The machines are getting bigger and bigger and heavier, so they destroy the ground.
Because the farmers use those cooperatively ( to expensive) everything is harvested at the same time.
Meat industry needs silage to feed and exports the surplus of meat to poor countries which leads to the refugee problem, because the foreign farmers loose the income.
Green energy needs every plant so everything is harvested once a month, road sides, groves....

To improve the situation farmers have to plant field sides with flowers, but those get the spraying drift from fields.
The insects have no nesting places and no plants to feed larvae. Birds starve.

In the private gardens grasses and stones are a trend, no natural settings anymore. Gardens look like indoor rooms.
Trees are exotic and have no flowers.

Man was a bad experiment, the only mammal who destroys his basic living conditions.
