1 Chapter 12 Food, Soil, and Pest Management

2 1 Industrialized meat production has harmful environmental consequences. These include all of the following EXCEPT: The use of large amounts of energy Contributing to the eutrophication of the Gulf of Mexico Contributing to global warming Polluting the air, water, and soil with manure Natural control of pests

3 2 Which of the following techniques helps to limit soil erosion?
Clear-cut logging Off-road vehicles Terracing Deforestation overgrazing

4 3 Many crops are now being engineered so that pests do not eat them. These are called: Genetically modified crops (GMOs) Plantation agriculture crops High-input agriculture crops Hydroponics macronutrients

5 4 One way farmer can help to reduce soil erosion is using soil conservation methods. Which fo the following is an example of soil conservation method? Waterlogging Deforestation Planting on already eroded land Alley cropping Clear cutting

6 5 Which of the following would be a disadvantage to using pesticides?
Pesticides eliminate pests that spread disease Pesticides can bioaccumulate up the food chain Pesticides help keep the price of food down Pesticides work fast Pesticides are profitable

7 6 DDT was a very effective pesticide; however it remained in the environment for years. This is known as: Broad-spectrum agent Genetic resistance Pesticide treadmill Persistence Financial treadmill

8 7 Which of the following practices would be a way that a farmer could grow crops organically? Using pesticides in limited amounts and only on specific days Only using pesticides that are water soluble Planting crops at times when the bugs are not around to eat them Doing aerial spraying for bugs rather than applying at the crops level Spraying pesticides on the roots so that the part of the plant that is eaten is not contaminated

9 8 A method of using biological control to control pests is to
Bring in natural enemies such as predators, parasites, and bacteria Utilize synthetic herbicides Allow wind to carry pesticides from one region to another Use broad spectrum agents Use a second-generation pesticide

10 9 The goal of integrated pest management is to
Wipe out as many of the pest species as possible to save crops Wipe out as many of the pest species as possible to save human lives Genetically engineer as many crop species as possible to eliminate the need for pesticides Encourage farmers to grow organically, eliminating the need for pesticides Use biological, chemical, and cultivation techniques in coordinated way to eliminate pest species

11 10 One way to successfully incorporate genetic engineering is to
Add pesticides to the DNA of the crop plant Cross a crop plant with a native variety Bring in hormones to control developmental processes at different stages Use biological control by importing natural predators Get on the pesticide treadmill

12 11 Raising fish in underwater pens is one way to solve the overharvesting problem. This is known as: Aquaculture Organic fish farming Ocean dumping Restoration Maximum sustainable yield

13 12 A more sustainable form of meat production is to
Graze beef on local lands Switch to poultry and farm raised fish Inject cattle with hormones to get more muscle mass Raise more animals per square acre of land Raise beef rather than pork
