AGRISCIENCE WORTH 1000 Point Bee Crisis
Agriscientists are quite concerned about the decline in the United States’ ongoing decline in bees. Do some online research about the causes and consequences of this problem. Write a two- to three-page essay on the bee crisis and be sure to include information about the following points:

How long it has been going on and how quickly the population is declining
Theories about the cause of the decline
The impact of the decline on the environment (use systems thinking to discuss all the consequences, not just those for plants)
The impact of the decline on agriscience and/or agriculture
Two suggestions for approaching the crisis and why there is reason to believe they will be effective
If all of these points are adequately covered, you will be using your fact-finding and critical-thinking skills. Also, remember what you learned in Unit 1 about reliable web sources. Make sure that the information you are gathering is from reputable sources and that you provide a list of articles and websites you used.

pre-sliced bread is a relatively recent development in baking technology. previous to that, it was always sold in a bakery in daily-made contiguous loaves with no wrapping, and was moderately perishable, usually being used with a day or two (which is why every bakery had a discounted “day-old” bread table.) therefore, pre-sliced bread would grow stale quickly. the hard crust provided a protective layer, and once the exposed dry slice left from the previous cut was removed, the interior was still soft.

what keeps bread soft is the moisture retained in the crumb (the light spongy part that’s not crust). the reason the crust develops is the surface of the dough gets exposed to hot dry air during baking which browns the outer layer and seals it, preventing all the moisture from escaping the dough. longer exposure to air will also eventually cause your bread to lose flavor and become stale.

people were used to cutting slices as they needed them and storing bread in a specially-made wooden or metal breadbox or pail with a lid to preserve it longer, but the first automatically sliced commercial loaves were produced on july 6, 1928, in chillicothe, missouri, using a machine invented by otto rohwedder, an iowa-born, missouri-based jeweler.[1] pre-sliced bread would indeed dry out, were it not for another 20th century technology: the plastic bag. bread could now be pre-sliced, and if the enclosing bag remains sealed as much as possible, the bread will remain soft and fresh for longer than if sitting unwrapped on a shelf or enclosed in a bread box that is not air-tight. sealed packaging meant bread could also be sold on store shelves and eliminate frequent trips to a bakery.

sealing bread in a plastic bag had another effect: the moisture in the loaf will re-distribute into the crust and soften it, which is sometimes more pleasing in a sandwich - especially for children whose teeth might not yet be strong enough to tear through a hard crust. a homemade loaf of bread can be sealed in a bag overnight and the crust will become soft like store-bought sandwich bread.

these were novel changes in how bread was produced and sold, which led to the coining of the phrase “the greatest thing since sliced bread.”
