what aree some good ways to do this
In the world of nuclear bombs, smog, and foul water,environmental understanding needs help from the scientist
shows how science to understand the environment has only led to the climate crisis
technician, industrialist, agriculturalist, or pub-lic official who has has condoned or participated in theassault on the environment
important to take not just economic intterests but also environmental needs
The preceding pages provide a view of the web of lifeon the earth. An effort has been made to develop thisview from available facts, through logical relations, intoa set of comprehensive generalizations. In other words,the effort has been scientific
talks about his structure-how he uses examples that come from observations/connections-scientific backing
Payment of this price cannot beavoided; it can only be delayed
our inefficient food systems will cause problems
oil-rich poten-tate
fossil fuels to mass produce food ruins environment
on pain of death
animal agriculture
caution or prudence
only possible if we stop mass production and creeation of harmful/unknown substances
an-made organic substance is synthe-sized with a molecular structure that departs significantlyfrom the types which occur in nature
doesnt work bc nature knows most about nature
relevant to the field oforganic chemistry
includes many connections- parallel to his topic of connections
“R & D.” I
what does this mean?
alludes to outside examples like "a watchmaker knows best to make his point"
Mercury vapor iscarried by the wind
important to go deeper in understanding how things are released back into eenvironment
Tracing ecological paths is important to understand effects of where things go ex) discarding mercury -> enters ocean -> toxic to marine life
Where doesit go?
an important question to ask to understand effects or our activiies on our environment
waste
nutrients excreted into environment are returned back to natarual processes and cycled back
The Second Law of Ecology:Everything Must Go Somewhere
everything should be returned back to the environment; system of trash/waste doesnt work
a result of its variousinterconnections and their relative speeds of response
more connections->more complexity->more resistance
ate character-istics
ecosystems also depend on abiotic factors like time/absorption
The First Law of Ecology: Everything Is Connected to Everything Else
backed by numerous examples through observation of nature
Eutrophication- too much organic matter -> kills bacteria -> more organic matter -> system collapses
eutrophication
an eexample of alinear system/feedback loop that doesnt work
oscillating system
linear/oscillating systtems dont work bc there is nothing too balance if too much of something happens
course of the ship
xample within and example to show the usee of. connection in ecology
linked
food web shows the link between species
Each species is suited to its particular environ-mental niche, and each, through its life processes, affectsthe physical and chemical properties of its immediateenvironment
species dpend on environmental factors and affect the environment through their lives
zone,
decreases solar radiation
carbon dioxide concentration inthe air, the larger the proportion of solar radiation
leads to increased fossil fuels and plants
changes in the composi-tion of the air can have strong effects on the amount andkind of solar radiation that reach the earth’s surface
cycle: sun effects composition of air and composition of air affects solar absorption
inversion
layer of warm then cool air
weather
relation between weather/water cycle
liquid water to water vapor
an effect of solar energy
weather cycle is driven by the sun’senergy,
another type of cycle involving solar energy
nitrate content of natural surfacewater is very low
nitrogen content in water depends on the way it works in soi; it's in water, soil, and air so can't be studied separately
why we have failed to understand the environmentand have blundered into destroying i
by separating ppl on either side oof the link we are destroying the environmnt due to isolation
Such a link enhances thecomplexity of the system, the fineness of its network, andthereby contributes to its stability
link or connections increase stability of a system because there is checks/balances-> weakened links->weakened systems
Soil porosity
this is also dependant on humus: efficient if soil has more porosity
natural concentrationof nitrate in the soil water is very low
this is because it takes along time for humus to release nitrate
decay of plant matter and of animal wastes
nutrients go back into nature from animals
nitrogen fixation
helps nitrogen enter soil through bacteria
soil
needed for plants and in turn, animals
strongly connected at a crucial point
This process itself shows the connection of air, soil, and life it involves soil porosity and the chemical reactions of nitrogen in the air and life matter
this is why observing things separately doesnt work
style-gives many supporting examples to show the connection between humans/nature, and connections between processes of the environment
irst sign of human poverty is a re-duced intake of nitrogenous food
some parts of observation like chemical reactions can point out different things like need for nitrogen/ health/relation to poverty
separate views
these separate aspects need to come together bc they are only a sliver of what needs to be observed and understood
biochemical processes
different cycles that help maintain balance in ecosystems
e multiplicityof living things in the environment:
how living things interact with their environment
spatial complexity
what does this mean?
The existence of the environ-mental crisis warns us that this is an illusory hope.
existence is connection so we have to treat it that way. studying things individually has only led to environmental issues
eciprocal interdependence
we depend on earth and its life and the earth and surrounding life depend on us to to take care of the earth -> mutualism
always produces carbon dioxide
our processes use up organic compound and generate CO2 -> need a system of checks/balances (ie. plant/geochemical processes)
The geo-chemical origin of organic compounds has been imitated
our research is directly based upon the forming of the earth
hydrogen, oxygen, and nitrogen
it's amazing that so much could form from just these 3 elements
complex skin of the eart
does this phrase allude to anything?
the airplane, like man, could not exist
connection between the way tech runs and people work
fatal illusion:
we distance ourselves from nature but depend on it to distance ourselves
ntimate understanding of this environment
indigenous people understand nature much better than we could by living in harmony with ut
society is designedto exploit the environment as a whole, to produce wealth
capitalism, factory farms, child labor, environmental degradation, etec
destruction
climate change
circular, self-perpetuating one.
life is connection
interdependent19living
mutualism/dependance on nature can be understood by looking at workings of environment
energy for processes depends on nonrenewable energy-> development of cycles(like checks and balances) ->need for living sustainably
free oxygen
allowed more types of life to emergee (terrestrial/marine)
later co2 emerging from depleting organic substances was converted back into organic substances
will something like this be able to happen from the greenhouse emissions we're emitting?
free oxygen
free oxygen allowed creation of ozone layer for protection against uv radiation
first life used up organic compounds for food, like how we're using up nonrenewable sources for materialism
organic substances came from early elements of earth's atmosphere now we depends on those to nourish ourselves; connection to earth?
organic soup
mixture of organic compounds -> life as we know it
environmental processes gave rise to organic compounds present in life and functions of life
all complexity comes from just a few elements. What does this mean?
We ourselves come from the Earth's elements. How does this affect our need to live in harmony with nature?
What will be the effects of a ruined environment on lives, politics, and the economy? What can we do to fix it?
ironic bc the very technology that we use to distance ourselves from the environment depends on the environment
illusive effects on health, society well-being; we depend on nature but isolate ourselves from it with tech
indigenous people like bushmen of africa have more knowledge than our scientists do on natural world and how to work with it
learning comes by doing (living in nature->understanding it)
ironic- we depend on it but exploit it and other innocents; roles: environmental stewardship?
we are draining earth's resources by taking more than the environment can handle -> effects of climate change
