What is the anthropocentric ethics?


● Chapter 11 water

● Colorado river no longer reaches the sea due to dam usage and lack of water ● Water quality

○ Dilution is solution to pollution 

○ Lead poison affects the brain with neurotoxins that are very harmful ● Pollution

○ Point source - form a specific location such as pipe or factories

○ Nonpoint source - from a variety of course across a landscape

○ CAFO = confined animal feeding operations these can cause huge methane issues. Don't forget about the age old question of The endocrine system functions as the collection of what?

● Treatment plant

○ WWTP = human waste primary treatment - removes floating particles by mechanical processes

○ Secondary treatment - biological

■ Decompose suspended or organic material : reduces BOD (biochemical oxygen demand) measures amount of organic material (sewage sludge) ○ Tertiary treatment - Biological / chemical, advanced wastewater treatment methods that are sometimes employed after primary and secondary treatments - reduce phosphorus and nitrogen gas

What are the services of ecosystem?

We also discuss several other topics like What are the four criteria for identifying domesticated animals?

● Sewage

○ Enrichment - fertilization of a body of water by high levels of nitrogen and phosphors Increases in biological oxygen demand

○ Amount of oxygen needed by microorganisms to decrease biological waste - as BOD increase dissolved oxygen decreases.

● On site wastewater treatment

○ Typical of households that use septic tanks (25% of houses in the US ) ○ Septic system - underground tank that uses leach field to disperse dirty water ○ Grey water - water from sources other than toilet If you want to learn more check out What is the rejection of realism?

○ Chlorine - by products are linked to numerous cancers, miscarriages and birth defects Don't forget about the age old question of What are the similarities between hospitality and tourism?

○ Ozonation - used by GUC , Prevents tooth decay - linked to cancer, kidney disease

● Water saving techniques

○ Desalination - converting seawater to freshwater

How to prevent soil erosion?

○ Reverse osmosis - filtering out salts -expensive (Cost and Energy) ○ Reuse grey water for other practical uses (sink water becomes toilet water) ○ Wastewater is treated and reused for irrigation

● Chapter 12

● Nitrogen is the most abundant element and is necessary for life If you want to learn more check out Are bacteriostasis and bacteriocide the same?

○ Microorganisms transform nitrogen gas to usable forms

○ We can only use natural nitrogen for positive life

● Europhiantion

○ The human actions that make natural water worse with bad nutrients ○ Phytoplankton - use algae to grow and clean fresh water

● Phosphorus is abundant in crust of the earth but is absent from the atmosphere ○ Humans impact with mines to gather phosphorous disrupts ecosystems ● Sulfur cycle 

○ Weathering and volcanic activity releases unusable forms of gas ○ Flux of sulfur into atmosphere high but residence time is low Don't forget about the age old question of What is the benefit of brainstorming?

○ Human impact - mining fossil fuels and burning them has doubled amount of sulfur released which causes acid rain


● Dust bowl

○ Great plains has low precipitation and is subject to drought

■ 1930-1937 severe drought

■ No natural vegetation roots to hold soil in place

● Preventing soil erosion

○ Not tilling soil - cover crops - contour farming

● Externalives

○ Unintended side effect of one or more parties

● Ecosystem services

○ Provisioning services

○ Regulation services

○ Cultural services

○ Sulporties services

● Environmental

○ Ethics differ - intrinsic value - people, organisms, or objects are valued ○ Industrial value - things are valued as a mean to something else ○ Western worldview - human superiority and dominance over nature ○ Deep ecology worldwide view - all species have equal value

● Ethics

○ Anthropocentric ethics = human centred

○ Biocentric ethics = all things important

○ Ecocentric ethics= communities and ecosystems and their intermantes are important

○ Ecofeminism - women suffer more than men
