How does power generation impact aquatic ecosystems with respect to flow, quanuty, chemisty, and temperature?
|
temperature: Can use river continuum framework to understand how temperature should vary within a river system
flow rates: turbulent water can saturate water with oxygen. matching human needs to when water is available. chemistry: what is dissolved in water can create or overcome physiological stresses- salinity and nutrients turbidity: density of suspended solids in the water column |

What is desertification? How can irrigation cause it?
|
Conversion of rangeland, rainfed cropland or irrigated cropland to desert like land with a drop in productivity of 10% or more. Usually caused by a combination or overgrazing, prolonged drought, soil erosion, and climate change

|
What is the difference between point and non-point pollution?
|
Point pollution can be traced back to a specific location such as a pipe, whereas non-point pollution has no specific origin and is very difficult to trace back to a specific location such as runoff.

|
What is the importance of biogeography and grain production?
|
12
|
|
|
Why does grain production have a siginificant impact on the development of societies?
|
Grains were important, because people were able to store the grain for long periods of time, through all weather. They would feed the grain to the animals, domestications them. This helped end the hunting and gathering way of life and allowed more time to do other things. It also has high calorie content.

How do we as individuals impact the use of water with respect to daily use and food?
|
-Diversion of water into reserviors from streams and rivers
-Water depletion of reserviors -Pollution of aquifers, streams, rivers from humand and other wastes -Greatly increased runoff due to urbanization |

What is the relationship between industrial agriculture and an increase in pests?
|
Industrial agriculture has created an increase in pest due to mono cropping. When there is only one crop being planted, if one pest infects the crop the entire field is lost. Where as when there is a variety it may only affect one crop and leave the rest alone. Pesticide use increases, pests build resistance to pestcide.
