Answer from: Quest

development: floodplain development often directly impacts wetlands by removing vegetation (increasing bank erosion), and filling or draining wetlands for building sites. floodplain development sometimes indirectly impacts riparian wetlands through the installation of artificial stream stabilizing devices like rip-rap and bulk-heads that attempt to stop the natural meandering process which creates new wetlands and replenishes existing ones.

road building: most river valleys have roads and/or railroads. these structures squeeze rivers and streams by narrowing the floodplain. this destabilizes the river which has less room to meander and therefore has an excess of energy. the roads and railroads also affect drainage from uplands onto the floodplains, and many are built on top of areas that once were wetlands. such roads often create long, low-quality wetlands upslope of the road by interrupting surface and groundwater flows. these wetlands can attract wildlife dangerously close to roads. wetland loss caused by roads is mitigated through the restoration of other impacted wetlands although the replacement wetlands are not always of the same type and quality as those lost. see montana department of transportation's off-site wetland mitigation reserves map.

grazing: overgrazing harms wetlands through soil compaction, removal of vegetation, and stream bank destabilization. wetlands offer some of the best forage for livestock as well as a water source and cover, so livestock tends to spend a disproportionately large time in wetlands. there are many grazing strategies that discourage cattle from using wetlands. click on rwrp's web site for a discussion of these strategies.

agriculture: wetlands often have fairly flat areas of rich organic soil that is highly productive agricultural land if drained. for this reason many wetlands have been drained and converted to agricultural lands.

mining: historic mining has had a major impact on wetlands of the clark fork basin, particularly along the upper river where mine wastes have been deposited in the floodplain, creating the country’s largest superfund site. view the superfund site.

the epa also list the following as major human causes of wetland loss: logging, runoff, air and water pollution, introducing nonnative species. see examples of nonnative species here.

the following lists specific damaging actions commonly taken in wetlands.

dumping: dumping fill material buries hydric soils and effectively lowers the water table so hydrophytic (water loving) plants cannot compete with upland plants.

dredging: the removal of material from a wetland or river bed. dredging of streams lowers the surrounding water table and dries up adjacent wetlands.

draining: water is drained from wetlands by cutting ditches into the ground which collect and transport water out of the wetland. this lowers the water table and dries out the wetland.

diverting flow: water is diverted around wetlands, lowering the water table.

devegetation: vegetation plays an important role in wetland ecology by removing water through evapotranspiration, altering water and soil chemistry, providing habitat for wildlife, and reducing erosion. removal of vegetation can drastically and sometimes irreversibly alter wetland function.

damming flow: many ponds and reservoirs are constructed on wetlands. a flooded wetland cannot provide the same habitats and functions.

development of springs: pumping large quantities of water from springs lowers nearby groundwater and can result in the loss of wetland vegetation. compaction of springs by cattle can cause springs to cease to flow.

question 1

the reasons for the global discontent in the early 1900s were the following:

desire for independence was the main fight of many territories which were still under the control of colonial powers. dissatisfaction with peace terms of wwi . the best example is the case of germany, that was forced by the peace treaties to pay very expensive war reparations to the winners of wwi. some time later, german leaders broke relations and stopped recognizing the authority of those who imposed sanctions on their country, counting with the support of the population that was suffering the important economic consequences of the payment of reparations. overproduction of consumer goods which led to hyperinflation scenarios and very week currencies and economies.

question 2

the reasons for the great depression were the following, and these led to wall street crash in october 1929 and caused the subsequent great recession period.

high personal debt, that ended up with many bankrupt investors. falling stock price as everybody was getting rid of the stocks, many because they could not meet the amounts of money required by the margins that backed their investments.

question 3

italy: led by the fascists and benito mussolini and promised to restore the greatness of the roman empire. germany: led by adolph hitler and the nazi party and conducted anti-jewish riots in austriajapan: was controlled by aggressive military leaders and invaded countries for their resources

Athief was passing by a house under construction when he noticed that the ladder being used by workers on the roof had copper braces supporting the rungs. after making sure that the workers on the roof could not see him, the thief used pliers that he had in his pocket to remove all of the copper braces that he could reach from the ground. a short time later, a worker climbed down the ladder and it collapsed. he fell to the ground and severely injured his back. the thief was apprehended a few hours later trying to sell the copper for scrap. a statute in the jurisdiction makes it a felony for "maliciously causing serious physical injury to another." the thief was charged with malicious injury under the statute and was also charged with larceny. after a jury trial in which the above facts were presented, he was convicted of both charges. if he appeals the conviction for the malicious injury charge on grounds of insufficient evidence, how should the court rule? a affirm the conviction, because the thief was engaged in criminal conduct at the time of the act that resulted in the injury. b affirm the conviction, because the jury could have found that the thief acted with malice. c reverse the conviction, because there was no evidence that the thief intended to injure anyone. d reverse the conviction, because there was no evidence that the thief bore any malice towards the workers on the roof.
