Which of the following would be an environmental impact of high density animal farming?
bad smells
livestock can escape
water pollution due to runoff

When roots become saturated with water due to over-irrigation, it causes death in plant roots. This is called:
salinization
desertification
agroforestry
waterlogging
The systematic removal of rock or other substance for financial gain.
smelting
mining
urban farming
forestry
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
What is a natural part of a forest ecosystem and may be required for seed germination?
floods
tornadoes
fire
polar vortex

Overgrazing of grasslands can lead to reduced range quality. Two of the major effects of overgrazing are
erosion and desertification
eutrophication and increased methane production
higher fire potential and increased productivity
higher primary productivity and ammonification
Which of the following is an example of a solution to the tragedy of the commons?
Improving literacy among urban populations
Raising tax rates for large corporations
Inventing stronger antibiotics
Passing a law to set limits for fishermen
Emphasis on use of pesticides, herbicides, and monoculture
green revolution
agricultural revolution
industrial revolution
subsistence agriculture
Which of the following is a positive outcome of tilling?
reduced soil drainage
increased soil erosion
increased aeration
decreased crop production
One way a local community might regulate a shared and limited resource and reduce the tragedy of the commons is to ....
eliminate ownership of the resources and make them available to all
divide the resources into parcels and assign them to individuals
offer subsides to users of the resources in the form of tax breaks
reduce the cost of access to the resources
Which of the following would decrease with the manufacture, application, and use of synthetic fertilizers rather than organic fertilizers?
Recycling of organic matter
Groundwater pollution
Cultural eutrophication
Use of fossil fuels
Which of the following describes an unintended consequence that results from large-scale agricultural use of water from an aquifer?
The water table level rises too high, leading to excessive flooding.
Much of the water becomes too salty for human consumption because of saltwater intrusion.
Agricultural areas contribute to increased carbon dioxide in the atmosphere, leading to global climate change.
The rate of water use likely exceeds the rate of recharge, leading to lowering the water table.
Which of the following best describes the advantages and disadvantages of drip irrigation?
This method most efficiently delivers water directly to plant roots compared with other methods, and wastes less water, but it may be too costly for farmers in developing countries to use.
This method is suitable for a range of topographies and is easy to operate, but it requires a high initial investment in machinery.
This method delivers water to the field by pipes and water flows directly over the soil, but there is a large amount of runoff.
This method applies water directly to trenches dug in soil and is cost effective, but water is often lost to evaporation.
