Why Bees are Dying: Neonicotinoids

What Is Killing America's Bees and What Does It Mean for Us?
[...] Doan never really considered the possibility that the fault might not be his own until scientists at Penn State who had been testing his bees told him of news coming out of France that pointed the finger at a relatively new class of insecticides called neonicotinoids, or neonics. The first commercially successful neonicotinoid compound was synthesized by agrochemical giant Bayer CropScience in 1985, but it wasn't until the early 2000s that they began to be used extensively. Compared to older, more toxic insecticides, neonics certainly seemed to be a win-win: Though neurotoxins, they mess with insect brains far more than those of mammals, and their application is a breeze. All a farmer need do is sow a seed coated in neonics and the water-soluble chemicals get drawn back up into the plant as it grows. Referred to as systemic insecticides, they spread through the plant, making it resistant to predators. Neonics don't require repeated applications in a hazmat suit. Rain can't wash them away — but then again, neither can your kitchen faucet (unless you're eating strictly organic, you're eating neonicotinoids all the time).

Doan knew his hives had tested positive for the neonicotinoid clothianidin, but the results had seemed dubious because clothianidin wasn't even registered for use in New York state. That's when he learned that neonic-coated seeds weren't subject to the same regulations as sprayed pesticides, meaning that seeds couldn't be treated in New York, but they could be purchased elsewhere and then planted there, with no one the wiser. Furthermore, studies demonstrated that bees exposed to sublethal amounts of these neonicotinoids showed a loss in cognitive functions, including their ability to navigate home.

To Doan, this seemed like a breakthrough — a perfect explanation for why his bees hadn't just been dying, but disappearing altogether. He testified at the Environmental Protection Agency. He testified in front of Congress. He was interviewed for a Time magazine article on neonics in 2013, the very same year a report by the European Food Safety Authority showed "high acute risks" to bees from neonics and the European Union issued a ban on the three that are most widely used. Meanwhile, the Saving America's Pollinators Act, a congressional bill introduced in 2013 by Reps. John Conyers and Earl Blumenauer that would have taken neonics off the market until their safety was more definitively proven, never made it out of committee. (The bill was reintroduced this spring, but its fate remains uncertain.)

Doan waited expectantly for the EPA to step in and address the situation: "When I first started learning about this, I'm like, 'Well, the EPA's there to protect us. We don't have to worry about this, because the EPA's here to help.'"But as the years passed and the use of neonics spread, it started to seem that maybe the EPA wasn't there to help beekeepers after all. To Doan, the mystery of colony collapse disorder deepened. He no longer wondered what was killing his bees; he wondered why steps weren't being taken to save them. [...]
The EPA is doing nothing, is anyone surprised? And agribusiness is looking for new ways of pollinating without bees, or producing a genetically altered bee. Just what we need, Frankin Bees to go with our Frankinfoods.

The bee's aren't affected by the toxin immediately, the effects only start to show up 3 months later. The bees become confused, their cognitive functioning is impaired, and they can't find their way home to the hive. They can't function, and the hive dies.

And since the insecticide is systemic to the plants, we are eating it as well. What are the long term side effects of that? If it does this to bees, what would long term exposure do to people?

More poisons from China: poisonous walls?

If the contaminated foods and drugs don't get you, the drywall will:

Not-so-great wall of China: Imported drywall could be toxic
[...] Florida homeowners have complained that the drywall in their homes, which was imported from China, is not only giving off a foul odor like sulfer, but is also emitting corrosive gases that are destroying home appliances. There's one documented case of the sulfide gases from this drywall rotting the copper coils of an air conditioner.

So you can just imagine what it's doing to people's lungs.

In fact, some homeowners with this drywall have already filed lawsuits against builders and suppliers, claiming that they're not only surrounded with walls smelling of rotten eggs, but that they're also suffering from sore throats and headaches as a result.

The rotten egg smell is no surprise. The Chinese drywall has large amounts of sulfer in it. In the U.S., the chief component of drywall is gypsum. It's just a shot in the dark, but I'm guessing the reason there could be high levels of sulfer in the Chinese drywall is that sulfer is cheaper than gypsum.

The Chinese drywall entered the country during a building material shortage from 2004 to 2007 (spurred by the rebuilding boom in the aftermath of Hurricane Katrina), so the homes using it were completed recently. [...]

It seems that the heat and moisture in Florida literally bring out the worst in the Chinese drywall. At one point, the writer advises "don't buy anything from China". Yeah right, easier said than done. Practically everything that is manufactured nowadays comes from China.

And the truth is, not all their stuff is bad. But you do have to be careful. I don't knowingly buy any food stuffs that come from China. When it comes to appliances or consumer electronics and that sort of thing, I do some research first. Contaminated drywall was something I had never considered, but I guess I will have to add that to "the list".

We have a trade imbalance with China. They need us to buy their products, and we need to buy them. But if we only buy the good stuff, hopefully they will get the message eventually and only make good stuff for us to buy. Hopefully. For our sake and theirs.

Of course, we could cut our corporate taxes and bring those manufacturing jobs home, but I don't see that happening any time soon. In fact, the opposite is happening. So for better or worse, we are going to be dealing with China for quite a long time, I think. I'm hoping for "better".
