Environmental Awareness

 

I.              Man's relationship with nature and the god(s)

Man & nature are harmonious. Nature subjugates man. Man holds domination.

Creation out of chaos

Notion of time

Nature as ordered

Ecological regularity

Greek – Gods as creator and designer of nature. Nature as ordered for use by god(s) and by man. Man as manipulator of environment.

Greek & Roman –

·          Greek & Romans varied concepts of environment

·          Traditional – world as sacred – gods of nature (some human qualities)

·          View later questioned – philosophers “discover truth of nature through reason”

·          Nature revered, impacts provoke reaction of god/goddess

·          However, obeying religious ordinances conflicted with self-interest – environmental degradation

·          Pantheism

Medieval – Monotheism

In creation stories under monotheism the role of god as the agent of creation varies. Under deism: God transcends the world, but does not actively participate in it. God created the world, but allows it to run on its own following the rules used to govern all activities. Under theism: God exists both outside the world and within the world. God both created the world and participates in it. God’s appearance is referred to as theophany.

Modern –

 

II.            Nature's order as knowable

Greek & Roman – Reason & Causation

·          Nature as ordered

·          Preserve natural order – some protections

·          Greek rationalism – nature ordered & followed logical principles (laws)

·          Principles known through reason - “discover truth about nature through reason” – weakened religious beliefs including limited environmental protections

·          Aristotle

·          hierarchical system: plants > animals > man > use of nature for human good

·          view of environment as effects on humans

·          environmental degradation inherent

·          influence carries to modern

·          Causality:

o         Material cause – material out of which things are made

o         Formal cause – essential characteristics

o         Efficient cause – what brings into being - limited to man

o         Final cause – purpose for what something is made – end

Medieval – Causation

·          Explanations in terms of final cause – emphasize formal cause

·          Environment – rational manifestation of god

·          World created by god

·          Causation - due to forms inherent in substances, and there is a division of the substances involved into agents and patients

Modern – Causation

Features of modernity - rejection of the Aristotelian four causes - replaced by view that only sort of causation is mechanical — i.e., particles of matter colliding into one another in accordance with the laws of motion - ‘efficient’ causation, different from Aristotle’s.

·          Bacon

o         interest in technology

o         purpose of science and metaphysics was not merely to understand, but power to transform nature

o         For innovation, we need knowledge of forms, which is the province of metaphysic

o         “in nature nothing genuinely exists apart from individual bodies”

·          Causal Processes

·          Probabilistic Causal Processes

 

III.           Environmental Impacts Common to Many Civilizations

Deforestation, Overgrazing, Fire, and Erosion

Deforestation – fire, timber, overgrazing

·          Slash and burn agriculture

·          Fuel, charcoal production and manufacturing processes, building ships, houses and castles, and mining. From offertory worship of the gods

·          Charcoal – heat, mining (stone, metals), use of metal, pottery - kilns

·          Woodlands and fields for hunting

·          Urbanization

·          Forest stallions for reseeding. Laws governing who has access to woods and fields. Laws governing hunting and hawking - Political Economy of timber – some management

·          Climate change, desertification

·          Deforestation disrupts water – runoff – soil erosion

Soil Erosion

·          Deforestation disrupts water – runoff – erosion

·          Alters shore, waterways – fish, bird habitat – marsh > insects > disease

Overgrazing – cattle, sheep, goats, swine > various preferences, repeated throughout history and in many cultures

Green spaces

·          Gardens, parks, and protected areas

·          Greeks & Romans – gardens & natural tracts

o         sanctuaries for gods/goddesses

o         divided, holy & ordinary

o         worship outdoors

o         some sanctuaries large, old-growth

o         hunting & pleasure for rulers

o         regulation & management

Fire

·          Forest – deforestation

o         Agriculture

o         Hunting

o         Urbanization

·          Urban

o         Fire fighting - Fire brigades established (26BC)

o         Prevention/fighting in homes

 

IV.           Wildlife Depletion

·          Food production among Greeks, Romans, Medieval, and Modern times

·          Egyptians decimated wildlife from hunting, birds from netting

·          Egyptians basically eliminated trees for construction, fuel, and sacrifices to the gods

·          Many issues similar throughout periods – Greek, Roman, Medieval, Modern

·          Habitat destruction

Greek & Romans

·          Wildlife suffered reduction in numbers

·          Some extinction, habitat destruction & hunting

·          Recognized possibility of extinction

·          Hunting > gods (pastime, protected, controlled, festivals)

·          Wildlife refuges

Food

·          Subsistence

·          Markets (led to depletion)

·          Defense of agriculture

·          Habitat destruction

o         Land cleared for agriculture/food production

o         Overgrazing

o         Irrigation

Military

·          Animals used on battlefield

Entertainment

·          Romans used wildlife in arenas

o         Elephants, rhinos & zebras – extinct in N. Africa

o         Crocs, hippos under pressure along Nile

 

V.            Agricultural Production and Decline

·          Irrigation, flooding, soil salinization, soil laterization (Egypt and other riverine cultures)

·          Erosion, terracing, planting trees. (Greeks and Romans)

·          Plowing strategies, tilling, dung fertilizers, crop rotation (Medieval agriculture)

·          Intensive versus extensive agricultural practices, modern fertilizers, pesticides, genetic cropping.

Greeks & Romans

Since the agricultural revolution social commentators have noted that production falls as soil fecundity wanes. Declining productivity meant inability of farmers to feed families acute starvation or chronic malnutrition, inability to generate surplus income to have more children or if single, to enter wedlock and start families. (Crop shortages, failures, and increased peasant taxation often precipitated peasant revolts against the landed aristocracy.) Farmers abandoned fields and migrate searching new lands. This pattern of farm and move accounts for the expansion of settlement pattern from old to new territories – peasant communities not stationary. Length of land tenure varied depending on type of soil, types of crops grown, and availability of water and weather.

·          Crops – barley, wheat

·          Vineyards & orchards

·          Domesticated animals

·          Basic agricultural tools & machines

·          Value of manure recognized, debating the relative merits of sheep, goat, cattle, horse, pigeon and human dung

·          Plowing back of weeds - replenish soil

·          Green manure - composting lupine, bean, vetch plowed under

·          Liming the soil was accomplished using limestone, chalk, burnt marble, and marl

·          Two - crop rotation (legumes vs. other)

·          Seed selection to increase yield of crop grown versus amount of seed sow

·          Greek agriculture was more ecologically sustainable due to small acreage farms. Roman farms organized as (ranches) latifunda stressed monoculture and overgrazing were more stressful on soil and vegetation.

·          Erosion control - ditching and terracing were used in hilly terrains - labor intensive

·          Irrigation systems in riverine culture to control flood waters. Dams, cisterns, and reservoirs to capture rainfall or spring run-off.

·          Technologies to lift water in elevation shaduf (pivoted, counterbalanced pole with bucket), spiral Archimedean screw, two-cylinder Ctesibian force pump, and noria.

·          Aside nature of criticisms of theory--idiographic vs. nomothetic, statistical heuristic and statistical heuristics based on case studies.

·          Agricultural decline

o         Soil exhaustion, despite knowledge of importance

o         Erosion control – destroyed by war

o         Salinization by irrigation

o         Poor agricultural policy – taxation, military, high expectations

Medieval

·          Climate in Europe warmer by 1 to 2 degrees - expanded acreage and extended the altitude by some 200 meters in growing crops

·          Development of a padded harness - transition from oxen to horses for transportation of goods and plowing the fields - teams of four, work faster, cheaper to feed

·          Horse teams could pull larger loads in the Medieval ages than during Roman period (2500 kilograms versus 500 kilograms Theodosian Code 438)

·          Horses required oats - another crop production

·          Iron horseshoes - increased the work capacity of horses, more efficient in military

·          High wheeled plow and moldboard plow allowed cutting deeper furrows, plowing faster - horses using the wheel could plow more land faster

·          Farmers cooperated in plowing operations, changing the plot from small squares to larger plots that were contoured

·          Seed selection practices improved. For 1 bushel of seed, yields ran about 4 bushels, marked improvement over earlier production levels.

·          Crop rotation (3) - 1 plot winter, 1 plot spring, 1 plot fallow. Fallow plots were manured and green-manured and plowed twice

·          Nutrition and diets were improved during the period. Farmers income was up. Greater social stability among peasantry.

·          Major products vine, beer, and wool production. Aside on water power.

Modern

·          Surplus – division of labor

·          Monoculture – stress on soil

·          Agribusiness

·          Synthetic herbicides/pesticides/fertilizers

 

VI.           Technology and Pollution

Among the ancients pollution meant contaminating the water, smoke and noxious odors in the air, waste from humans, animals, and fowl, and production by- and end-products. Ancients commented on linkages between increased efficiency of technology and increased demands placed on environment thru extraction of resources, manufacturing processes, and end-production pollution.  Extractive industries included mining, quarrying, digging for pottery, glass, bricks, concrete, mortar, fertilizer, limestone, marble.

·          Technology

Human technology has always caused environmental degradation – though worse in modern era as technology has become more sophisticated.

o         Extractive Industries

§          Mining, quarrying – processed – metallurgy, ceramics

o         Greeks & Romans

§          Greeks used open pit, tunnels, open chamber.

§          Minerals mined: gold, auriferous quartz and auriferous galena (silver), copper (chalcopyrite), iron from pyrite and hematite, zinc from calamine, mercury from cinnabar

§          Salt mines used quarrying techniques

§          Romans added hydraulic mining; used sluice technology. Water used to separate ore from over burden (sluices and settling tanks)

§          State controlled mining leased to private entrepreneurs - slave labor

§          Stone was cut by picks and hammers. Bronze saws were used in quarrying. Rocks were broken by heating stones and pouring vinegar on them to crack them. (Egyptians in colder climes drill holes in limestone, poured water holes, froze - expanding ice cracked rocks.)

§          Technology to light tunnels - fatwood, oil and wick lamps

§          Drainages of mines accomplished using Archimedean screw, piston pumps, waterwheels. Underground streams were diverted.

§          Massive amounts of wood used for energy and timber to shore up mine tunnels led to deforestation.

§          All digging operations led to scarring of land.

§          Metallurgy - separation of metals from ores, smiths work metal in jewelry, tools, utensils, armor, and weapons.

o         Medieval

§          Quarrying for stone for construction of buildings, bridges, and highways

§          Mining under many cities

§          Tunnels often converted to water courses or sewers

§          Change of landscape

§          Mining for iron ore was of paramount importance - weapons, armor, horseshoes, agricultural tools, nails

§          Iron replaced wooden parts in many water driven machines

§          Silver, gold, lead, tin were sought after metals

§          Metallurgy and smithing major occupations

§          Control - kings and emperors, major source of income. In England laws were passed which allowed access to timber and setting up mining operations on anyone's property. (Appalachian coal operations?)

Pollution

·          Deforestation – largest problem during past eras – many, many uses for wood

·          Air

o         Domestic heating and manufacturing (wood, charcoal, dung, sea coal)

o         Greek & Roman

§          Dust from mining led to air pollution. Miners breathed toxic dust that discolored skin, lung diseases, or poisoned them.

§          Byproduct of production kilns, metal smiths

§          Fumes of noxious substances – headed, burned

o         Medieval

§          Industrialization – deforestation

§          Wood for building, machines, heat – smoke

§          Coal – smelters, kilns – smoke

§          London – 1st city to suffer man-made atmospheric pollution.  Substitution of sea coal led to reports of air pollution in London and bans against its burning in late 1200s.

o         Modern

§          CO2

§          Industry & private

§          Some regulations

·          Water

o         Sedimentation. Filtration. Aeration. Chlorination.

o         Greek & Roman

§          By product of mining - poisonous metallic salts run-off ruining water for drinking or irrigation

§          Erosion from diversion

o         Medieval

§          Industrial pollution – slaughter & tanning

§          Slaughter (butchers) – animal byproduct

§          Tanning – many chemicals used, washed down-river

§          Restrictions – kept out of cities, towns

o         Modern

§          Monitored for public health purposes

§          Industry

§          Point (factory w/stack) & non-point source (agricultural)

 

VII.          Sanitation and Waste Removal

·          Sanitation

o         Sanitation and waste removal (Human waste, Animal waste, Toilets and Sewers, Bathing and the notions of cleanliness)

o         Every culture establishes procedures to remove human waste, kitchen waste, water, and animal by products

o         Outdoor drainage ditches, latrines, and cesspools universal. Indoors squat holes, toilets, and drainage systems using copper, bronze, clay, terracotta, and lead pipes were reported variously in Egypt, Minoa, Greece, Rome, Middle Ages.

o         Copper > Iron and cast iron pipes > plastic pipes

o         Greek & Roman

§          Greece (Missiles of mirth-Aeshylus), Rome (law called Dejecti Effusive Act fined person who poured chamber pot out window during daytime)

§          Aristotle – move waste from camps

o         Medieval

§          Waste emptied onto streets or in ditches that flowed into cesspools, or eventually drained in to waterways

§          Waste was tossed over castle walls or privies or garderobes carried waste thru the stonework to stream below

§          Privies with pipes pipe drains, and with cesspools. Ditches, moats, and public latrines used available flowing water to sluice away filth

§          London Bridge has several privies -- "necessary houses or wardrobes." A number of public latrines were built by taxpayer money.

§          Waste dumped into streams and rivers - flow was sometimes stopped - unsanitary

§          Cesspools were numerous and sources of noxious odors and contamination for wells as well as sites of accidents where some would fall in and drown

§          Plague

o         Modern

§          Health commissions

§          Remove stench & disease

§          In many cultures the smell of human excrement and urine remains one of the most common odors

·          Bathing

o         Greek & Roman

§          Bathing was practiced for religious ritual, relaxation, cleanliness, bodily and mental fitness, or sociability

§          In Greece, free citizens were bathed at birth, before marriage, and after death

§          Removal or sweat, dirt, and hair with curved knives, a cold bath, and scented oil following exercise was routine in gymnos

§          Gymnos was site for training and educational enrichment for the Greeks

§          Rome had a most hydraulic culture - moved water great distances using gravity drop for water flow, aqueducts some 200 miles by 52 AD, underground tunnels, pipes, sewers (e.g., Cloaca Maxima), dams, drains, and pumps.

§          Roman Baths

·          By 4th century AD Rome had 11 public baths and 1352 public fountains

·          Public baths, thermae - important feature of Roman culture

·          Note public bath water was not circulated, filtered or regularly replaced. It was filthy. This standard of water quality persisted for centuries.

·          Public baths were open for citizens, supported by fees-- the rich, not the poor, male dominated - women were expected to pay 2x as much as men. Social etiquette demanded that one not stare at nude bathers of the opposite sex yet baths were places to conduct not only political affairs, but engage in sexual affairs - often stimulating public outrage and moral crackdowns. In fact, women who attended bathes had no claim to respectability.

·          Private baths were common with some 856 private baths by the 4th century AD

o         Medieval

§          No bathing – only religious purposes

§          Christianity – no bathing

§          Decline of Roman influence, rise of Christianity - value of cleanliness declined. Don't bathe, it washes away holy water. Public bath houses became centers for hot houses, stews, bordellos and eventually were closed.

o         Modern

§          Bathing again – cleanliness associated with moral purity

§          Late 1700s tools & goods for cleaning

§          Rise in level of cleanliness, though difficult

§          Development of housework – routine

§          Spring cleaning

§          Laundry

§          Today – thousands of cleaning products, many chemicals, etc

·          History of sewers

Open ditches > tubular pipes > water to flush > regulation (pipes-size/shape) > diluted w/water > treatment > modern sewers

·          Sanitation Movement

o         19th-century Sanitary Movement

o         Denied the germ theory of disease

o         Created public health infrastructure

o         Greatest gain for life expectancy

 

VIII.             Urban Problems and Legal Solutions

Urban Problems

·          Progression of human – population centers

·          Many environmental problems arise as large population centers form – ecological impacts multiply, carrying capacity diminishes – most problems discussed are direct outcome of urbanization

·          Western civilization - tension between urban & rural - more people, more problems (moral, social, environmental & esthetic problems)

·          Problems – social cause

·          Complex and formalized social organizations to meet demands for providing goods and services > centralized

·          Threatens status quo

·          More problems than rural life – food & goods (transport), sanitation, waste, pollution (water & air), noise, crime, disease, pests

·          Fire became a problem – quick to spread

·          Need for green space (gods/goddesses, hunting, gardens, Central Park)

·          Urban issues resonate throughout eras

·          Greek & Roman

o         Romanticization of nature - rural nostalgia expressed by Greeks urban dwellers who formerly lived in rural areas and missed the beauty, quiet, and clean air

o         Issues of defense

·          Medieval

o         Waste large problem

o         Fortification

·          Modern

o         Wealthy Romans and later magnates of capitalism (Vanderbilts, Rockerfellers, Whites) turned to the country or suburbs as an escape from urban problems. Summered by the sea. Traveled for relief from the din of urban life.

Legal Solutions

·          Humans have been interested in environmental quality for nearly as long as written records obtain – rules needed to protect life

·          Greek & Roman

o         Codes:

§          Limit days of agriculture trade on roadways, to be cleaned

§          Hours of business limited

§          Traffic limited to specific hours to limit congestion

§          To ensure cleanup of channels, cesspools, latrines - waste dumped mid-stream and to catch ebb tide

§          Fire brigades

§          Construction codes

·          Medieval

o         European population tripled between 1000 and 1300 – problems of handling expanding population (agriculture, sanitaion)

o         Town were harshly competitive, highly stratified, with rich elites & laborers

o         Economy was agriculture with trade

o         Assumptions about the environment:

§          1 - the earth planned -- God intentionally provided a home for man because he favored the rational over the irrational. Humans only rational animal.  Continued development - will of God's will

§          2 – humans as stewards - managing and protecting the resources.

o         Regulation:

§          Roadways supervised by government

§          Litter legislation

§          Hay and other fodder regulates as fire hazards

§          Animal waste on roads - size of herds regulated

§          Human waste not to be thrown on streets

§          Keeping roads clear for pedestrians, vehicles, business

§          Water use was supervised by government - water and sewer systems operated to have safe drinking water but more so for public sanitation

§          Waste removal

o         Codes derived from Justinian codes of ancient Rome

o         Towns and cities of north and north central Italy between 1000 and 1750:

§          Emphasis on local rather than regional response to environmental issues

§          Rational responses to perceived needs within the limits of scientific and technical knowledge of the times
