Widely used pesticides have been found in new research to block a part of the brain that bees use for learning, rendering some of them unable to perform the essential task of associating scents with food. Bees exposed to two kinds of pesticide were slower to learn or completely forgot links between floral scents and nectar.
These effects could make it harder for bees to forage among flowers for food, thereby threatening their survival and reducing the pollination of crops and wild plants.
.......
The new findings on the effect of pesticides on bee brains showed that within 20 minutes of exposure to neonicotinoids the neurons in the major learning centre of the brain stopped firing. Christopher Connolly at the University of Dundee, who led the peer-reviewed work published in the online journal Nature Communications, said it was the first to show the pesticides had a direct impact on pollinator brain physiology.
A parallel peer-reviewed study on the behaviour of bees subjected to the same insecticides found the bees were slower to learn or completely forgot important associations between floral scent and food rewards. "Disruption in this important function has profound implications for honeybee colony survival, because bees that cannot learn will not be able to find food," said Dr Geraldine Wright, at Newcastle University, who led the work.

(10,597 posts)No. We can do nothing to Monsanto, via the new Monsanto Protection Act, which was attached to the funding bill that PO signed late last night, while no one was watching.
I'm sure there was no signing ceremony.

Such bad news - where to go from here? I just don't know.

Did you ever hear Vandanna Shiva tell about what all has been going on in India, re Monsanto? I forget how many thousands of farmers she said had committed suicide in India because of their dealings with Monsanto cotton seed. They would buy it with what little funds they had, plant it and it wouldn't grow. Next growing season would come along and they would again scrape up the money to buy more seed. This went on and on and suddenly, farmers started committing suicide over it all. Prince Charles went over there himself so he could hear their story himself, and the little wives and family members told him everything. Prince Charles gave a big press release about it, and I haven't heard anything out of him since. And that was many years ago. I don't know, maybe someone here does, if the cotton plant requires bees to complete their growing cycle? Could be the insecticide is poisonous to the bees and therefore, the plant doesn't mature. Guess it would depend on when they spray it? I'm way above my pay-grade here, but something just clicked when I read this thread's OP.

I think I will google around to find something inspirational but man - what people won't do for money.

(814 posts)Our food sources have been forever damaged and changed and now none of these species is functioning as it should.
We have all been affected by this, when you can't digest the food you eat you end up with an endless # of autoimmune diseases that "there's a drug for". Is Monsanto invested in these drug companies who are creating the drugs to treat all these diseases that they caused?

Michael Wines, Mar 26, 2013, New York Times News Service :
The migration of the monarch butterfly is seen as a natural marvel and, for Mexico, a huge tourist attraction. But naturalists regard the butterflies as a forward indicator of the health of the food chain. Fewer butterflies probably mean there are fewer other insects that are food for birds, and fewer birds for larger predators, writes Michael Wines.
The number of monarch butterflies that completed an annual migration to their winter home in a Mexican forest sank this year to its lowest level in at least two decades, due mostly to extreme weather and changed farming practices in North America, the Mexican government and a conservation alliance reported recently.
The area of forest occupied by the butterflies, once as high at 50 acres, dwindled to 2.94 acres in the annual census conducted in December, Mexicos National Commission of Natural Protected Areas disclosed at a news conference in Zitacuaro, Mexico.

(2,578 posts)Organic gardening has been around since...well, forever, when I think of it.
However, in historical times, it began to be remembered/promoted in the 1930's by J.I. Rodale, the founder of Organic Farming and Gardening Magazine. They are still publishing, and tons of info is available for free at your public library, and on-line.

I would also suggest that people check out bio-dynamic gardening and permaculture.
There are tons of great resources on all of these topics.
My favorite garden books:
"Garden Anywhere" by Alys Fowler
"Lasagna Gardening" and "Lasagna Gardening in Small Spaces" by Patricia Lanza
"The Medicinal Herb Grower -Volume 1" by Richo Cech.
Poisons and artificial fertilizers are not needed, are harmful to all living beings, and kill earthworms and the soil microbes which create fertile soil in the first place.
I hope for the sake of all life on Earth, that more people work to educate themselves on this subject.
May the Earth be healed, for the benefit of all beings.

(53,661 posts)The only time I ever had to do something about insects was in a stressed environment (too hot, no rain, too windy) and had an infestation of grasshoppers that were eating everything down to the ground. Garlic, hot peppers, companion plants and chickens were unable to keep up with them. I ordered a strain of Bt that was mixed with oatmeal to put out that only affected them.
They ate it, lost their appetite, died, then ate each other which served to pass the bacteria to others which acted much like a stomach flu. It reduced their numbers so I could get a crop.
It occurs naturally in some areas if the soil conditions are right and there is sufficient rain. That wasn't the case there, but in less than a week the grasshoppers were no longer a problem.
I always used compost, mulch, natural manure and companion plants. This can be done by anyone. When one realizes that healthy soil is the key, and that it is a living thing, it's not hard to get away from other methods.
I don't know what they teach in school now, but it was the way to go for many years.
I mix up potions right here at home to put on my garden. Beer, fish emulsion, Epsom salt, galic, human urine, yada, yada, yada. PUt it in a front end loader and snap it on the end of the hose and away I go. It's all naturale. And I have lots of bees. Great big yellow jackets, which I called bumble bees when I was a kid. Got stung by one of those babies when I was a little girl and I will never forget it. Thought I was 'gonna die. (As Gilda Radner used to say it on SNL years ago..."Emily Lotilla?" Funny, because the bees and I peacefully coexist out there together all the time now. (In season, of course, which we still don't have yet because of the late winter.) ........."Never mind"...

(2,578 posts)Healthy soil is the key. It takes @ 3 years to build the soil up to have enough nutrients to grow healthy plants.
Sounds like you had to deal with a difficult conditions (too hot, no rain, too windy). That stresses the plants, big time.
A really interesting book on that subject is "The Secret Life Of Plants" by...I think it is Peter Thompson and Christopher Bird? Can't seem to locate my copy at the moment.
My home town is a hot bed for organic gardening. Many of our area schools have organic gardens and the kids get to plant and harvest produce which is used in the food served in the cafeteria.
I just wish more people would use organic methods. I hate the smell of the Ortho products. I can always tell if someone has used that nasty stuff.
Bless you, Sir. Wishing you a good evening.
