Environmental science?

Many of these are self explanatory.

1) Of course: Plants need water to grow and if you have to pipe the water in then your depleting the water from another area. I your considering ranching in this then the same thing applies but you also have to consider contamination from fecal waste plus any feed additives.

2) The southwest - the more arid regions

3) Flooding releases toxins, poisons, and contaminates which were "locked" in the soil, waste dumps, and other areas.

4)the plastic in the bottle - many "bottles water" is nothing but plain water placed into the bottle.

5)True - the ground acts as a filtering system and also gives time for the waste products to decompose before entering water system.

6)true and false: some of the waste in these run offs will be made safe by the plants; however, for most of the toxins that go down the system, the plants are not designed to handle and will not filter out or detoxify.

7)Yes: animal waste will make its way into the ground water, rivers and streams.

8)Absolutely: common sense

9)the small one of course - under the conditions that you state. However this may be a trick question - you need to know the rates of each i.e. the smaller on may have a higher rate of inflow and outflow and still be small, so the concentration can decrease faster than the larger one and so have a smaller concentration.

1, Yes if you buy those products, by buying them you support the use of water irrigation to grow them.

2 California, accounts for 11% of the fresh water used in the US, much of it for crop irrigation. Texas, Idaho and Illinois would be next, between them they use nearly one third of all fresh water used in the US.

3. Flooding waters coming from the land into a river system will wash in chemicals from the soil, often used in farming, bring lots of silt and soil which will clog the river, contaminate it with rubbish and sewerage and the fast flowing waters will erode the river banks to name but a few.

4. The bottle, transport and marketing, followed by the purification method.

5, True

6 False, connecting storm sewers to domestic sewerage systems will in the event of a large storm wash raw sewerage out into the environment.

7. Grain fed animals often are intensively farmed, this means they are kept in closed conditions and the waste they produce as slurry can if not properly treated end up in the water systems.

8, True

9,The smaller, the concentration would be dependant on the volume e.g 1gallon of pollutant in a 100,000 gallon pool gives a ration of 100,000:1 the same quantity of pollutant in a 1,000,000 gallo pool would be 1000000:1

Environmental science is an interdisciplinary academic field that integrates physical and biological sciences, (including but not limited to Ecology, Physics, Chemistry, Biology, Soil Science, Geology, Atmospheric Science and Geography) to the study of the environment, and the solution of environmental problems. Environmental science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.[1]

Related areas of study include environmental studies and environmental engineering. Environmental studies incorporates more of the social sciences for understanding human relationships, perceptions and policies towards the environment. Environmental engineering focuses on design and technology for improving environmental quality.

Environmental scientists work on subjects like the understanding of earth processes, evaluating alternative energy systems, pollution control and mitigation, natural resource management, and the effects of global climate change. Environmental issues almost always include an interaction of physical, chemical, and biological processes. Environmental scientists bring a systems approach to the analysis of environmental problems. Key elements of an effective environmental scientist include the ability to relate space, and time relationships as well as quantitative analysis.

Environmental science came alive as a substantive, active field of scientific investigation in the 1960s and 1970s driven by (a) the need for a multi-disciplinary approach to analyze complex environmental problems, (b) the arrival of substantive environmental laws requiring specific environmental protocols of investigation and (c) the growing public awareness of a need for action in addressing environmental problems. Events that spurred this development included the publication of Rachael Carson's landmark environmental book Silent Spring[2] along with major environmental issues becoming very public, such as the 1969 Santa Barbara oil spill, and the Cuyahoga River of Cleveland, Ohio, "catching fire" (also in 1969), and helped increase the visibility of environmental issues and create this new field of study.
