Read about each method used for managing for us and categorize each as “Eco-Friendly” or “Not-Eco-Friendly.”  Choose all of the following answer choices that would be considered “Not Eco-Friendly.”

According to the pie chart below, what is the largest cause of worldwide land degradation or land loss?   

Which of the following would be considered an advantage of underground mining? 

The California Gold Rush is an example of what type of mining? 

Loss of Wetlands   According to an article by the U.S. Fish and Wildlife, during the 1970’s and 1980’s about half of the wetlands in the U.S. were destroyed.  Wetland loss can add stress to remaining wetlands.  For example, if fewer wetlands are available to filter pollutants from surface waters, those pollutants could become more concentrated in the remaining wetlands.  Wetland loss can also decrease habitat, landscape diversity, and connectivity among aquatic resources.    Which group of organisms would likely be most affected by the loss of wetlands? 

One source of iron used by early humans came from _________.

Read the facts about In-Situ mining below and categorize each as an advantage or a disadvantage.   Select ALL of the advantages. 

Read the paragraph describing surface and subsurface mining.  Identify pros/benefits and cons/costs to each mining process. Choose All of the answer choices below that would be considered cons/risks of surface mining.   Deposits that are located on land and on or near the surface can be extracted using a surface mine.  Surface mines are giant holes in the ground.  Explosives are used to break apart the rock, while giant trucks are used to haul it out of the mine.  Some surface mining involves removing layers of rock or sediment above to expose the deposit.  In some areas, so much rock is removed that the process is referred to as mountaintop removal.  Many of the leftover pieces of rock and ore are discarded into giant piles and are susceptible to erosion and weathering.     Subsurface mines are much more expensive to operate than surface mines and thus are reserved for more valuable deposits.  Subsurface mining, in general has less potential for negative impacts to the environment, but there is often danger to the miners and a possibility of land subsidence.
