Which of the following environmental effects would most likely result from the clear-cutting of boreal forests by industrial logging operations?

• There will be an increase in atmospheric oxygen concentration, which will improve air quality.

• There will be an increase in farming on the cleared areas of land, which will reduce incidences of flooding.

• There will be an increase in atmospheric carbon dioxide concentration, which will contribute to climate change.

• There will be a decrease in the temperature of soil and nearby bodies of water, which will increase biodiversity.

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.

An insect population in an agricultural field is affected by monthly applications of a pesticide, as shown in the graph below. A likely cause of the overall increase in the insect population over time is...

• a decrease in the moisture content of the soil

• an increase in soil salinity

• the survival of increasing numbers of resistant insects

• an increase in the population of insect predators

• IPM

• contour farming

• aquaculture

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

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
