Level 1 Guiding Question: How does industrial crop production impact human health and ecosystems?
Write a description of what you think of when you heard the phrase "crop production"write your comment in the "class comment" section in Google classroom.
Look at the presentation above and notice it not complete, using a presentation software file (i.e. powerpoint) that your teacher has prepared for you please complete the slide show by following the instructions that are included with the file. When complete please remember to submit or "Mark it as done".
Level 1 Investigation: Ecological Impacts
Select one of the "Ecological Impacts..." on the above handout. Resources provided on the website to the right. Once you chosen your impact and finished your research start making the flow chart entitled: "Impacts of industrial crop production". When completed please submit or "Mark as done".

Level 1 VDO: Ecological Impacts
Erosion is particularly damaging because the top layer of soil (topsoil) is richest in organic matter. Erosion can also contribute to water pollution by transporting pesticides and excess nutrients into nearby streams and rivers. On much of the world’s agricultural land, fertile soil is still being eroded much faster than it can be restored by natural processes.
Soil ErosionTo provide crops with nutrients for growth, farmers often apply fertilizers such as synthetic nitrogen, minerals, animal manure, or human sewage. But when more fertilizer or manure is applied than plants can use, the excess nutrients become “too much of a good thing,” seeping down into groundwater or being carried into nearby waterways...

Many studies suggest insecticides are contributing to recent and dramatic declines in honey bee populations—a global phenomenon called colony collapse disorder (CCD).23–27 Recent surveys indicate that roughly 30 percent of U.S. honey bee colonies are lost each winter, in part due to CCD.
InsecticidesSome resources, such as fertile soil and fresh water, have always been essential to agriculture. Fossil fuels, by contrast, have been widely used in agriculture only since the early 1900s, with the invention of mechanized tractors and synthetic nitrogen fertilizers (manufactured using natural gas). These resources are called “fossil” fuels...

Pesticides are used with the intent of killing a target organism (pest), such as an insect, plant, or fungus that interferes with a food crop. Pesticides often have unintended effects on other, non-target organisms. Some pesticides are non-toxic to humans, while others are highly toxic.
Herbicide-ResistanceGrowing crops and raising animals for food depend on a reliable supply of freshwater. This resource is surprisingly scarce: of all the water on Earth, only 2.5 percent is freshwater; the rest is salty. The vast majority (99 percent) of freshwater is locked in glaciers, icecaps, or below ground, and is mostly unavailable.

Level 1 Elaborate: Infographics (the future of agriculture)
If current practices in agriculture continue, what kind of food system can we expect in the future?
Once you have answered the question you will make an infographic on how will our food supply chain be different?
Level 1 Review: How does growing food impact our ecology?
Take this review test!

Answer the following questions and record them on Vocaroo or your device's voice recorder and send it to your instructor via Google classroom.
1. If current practices in agriculture continue what kind of food system can we expect in the future? 2.How can ecological impacts affect human health? |
Level 1 Summary: Unit Test
Set up and create a website so that you can post your products. After you have completed your infographic you are to post it on your website.
