Concern over the routine use of antibiotics in raising livestock centers around:

Violations of S. Government policy that prohibits their indiscriminate use in livestock

A tentative link between antibiotics and cancer

The fact that the antibiotics may be toxic to small children

Sustainable agricultural practices are characterized by all of the following except:

GM (genetically modified) crops and foods:

May produce unexpected allergic reactions in some consumers

All of these choices are correct

May be resistant to pests, diseases, and stressful (weather)/climate conditions

Have been largely banned by the European Union

May have higher nutritional value than the original product

All of the following are subsistence agriculture practices except:

Which of the following statements about genetic diversity is false?

Low genetic diversity increases vulnerability to new disease-causing organisms

During domestication, selection often occurs for traits which are not of obvious value to humans

The majority of vegetable crops in the US are of only a few varieties

Much of genetic diversity is lost due to domestication

Wild plant and animal populations generally have high genetic diversity

Which of the following is NOT a component of sustainable agriculture?
