Organic farming products are more expensive because farmers do not get as much out of their land as a conventional farmer?

• YES

• NO

When roots become saturated with water due to over-irrigation, it causes death in plant roots. This is called:

• salinization

• desertification

• agroforestry

• waterlogging

When irrigation water evaporates, salts are left behind on the soil surface and can cause plant death or lead to

• soil salinization

• desertification

• waterlogging

• monocropping

One of the advantages to using genetically modified organisms (GMOs) is

• reduce the need for pesticides

• they are not regulated by the government

• the concern about safety to consume

• they can cause food allergies

Which of the following would be an environmental impact of high density animal farming?

• bad smells

• livestock can escape

• water pollution due to runoff

• improvement of feeding efficiency

Because global fisheries have dramatically seen a reduction in fish numbers, this technique has been used recently to supplement that loss.

• monocropping

• IPM

• contour farming

• aquaculture

A sustainable practice that requires farmers to leave the ground undisturbed when planting crops

• windbreaks

• contour plowing

• groundcover crops

• no till agriculture

Which of these best describes a practice that aligns with integrated pest management?

• increasing fertilizer use to improve crop yield per hectare

• introducing natural predators of a pest species to decrease their crop damage

• using pesticides earlier in the season to increase their effectiveness

• growing monocultures so that crops will be easier to manage

Sustainability

• The process of maintaining resources so they are not depleted or permanently damaged.

• The ability to read minds

• The ability to save resources for years and years

Livestock farming has shifted from

• smaller to larger farms

• larger to smaller farms
