There is an interesting CNN opinion article dated May 17, 2014 about the decline in bee population by Marla Spivak, an entomology professor at the University of Minnesota. Here is the sentence that got me: "Of 100 crop species that provide 90% of our global food supply, 71 are bee-pollinated." The article talks about many issues causing the decline of bee population, including pesticides. Dr. Spivak is quite a good advocate for bees; check her out.

Thanks, foray!
I ran into this on Twitter today.

Same info I'd seen many times, but presented in a new way!

Funny they didn't consider the meat as vulnerable.
I'm pretty sure the meat animals are raised on corn and other vulnerable plants.

Indeed, bees are responsible for pollinating the food that is eaten by animals as well as humans. So fruits, veggies, grains and meat are all vulnerable. And since we have over fished the waters as well, we had better pay attention.
I do want to make one "devil's advocate" point, however...some form of pest and weed control is needed to boost production and preserve our food supplies, especially when botanical materials are transported from place to place. Case in point, Japanese beetles were brought to the U.S. from Asia in such a manner. It obviously should be done in a way that would not destroy beneficial insects and other wildlife. Unfortunately, it is not always known immediately that there are ill effects. Another example, DDT. Once a chemical is developed and in mass production, it is hard to get it pulled off the market, as we have seen many times. Banned in the U.S. since 1972, DDT is still produced and exported from the U.S. and used elsewhere in the world today.

Important point!
I prefer the use of non POISONOUS methods unless the situation gets out of hand before it's realized.
I smother weeds with cardboard.
I know some farmers who put black plastic between their rows.

When I bring in my houseplants from their summer vacation on the deck, I unpot them, swish them in a bucket of water, and repot them in fresh potting soil.
I'm sure my ways are too labor intensive for mass production and distribution, but I am also sure that if people would just quit reaching for the poisons as a matter of course, better methods could be developed.
