Early Civilization’s Impact on the Environment
 As many 60,000 years ago there is evidence of fire being used to
clear forests in Tanzania
 Agriculture, building and wood fuel begin to lead to mass
deforestation and soil erosion in populated areas.
 7000 BC – Destruction of ancient forests in the Middle East at
the time are believed to have given rise to the story of the Garden of
Eden.
 6000 BC – Deforestation leads to the collapse of communities
in southern Israel and Jordan.
 2700 BC – Some of the first laws protecting the remaining forests were
decreed in Ur – an ancient city in Southern Mesopotamia.
Greek and Roman Influence’s
 500 BC – Greek coastal cities become landlocked after deforestation
causes massive soil erosion, resulting in siltation filling bays and the
mouths of rivers.
 Greek Philosopher Plato compared the hills and mountains of Greece to
the bones of a wasted body.
 One river in southwestern Greece – the Maender, was so heavily silted that
its twists and turns come to represent a river wandering; or Meandering.
 Ancient Rome – the largest city in the world at this time suffered from air
pollution from smelting and tanning, as well as runoff from garbage and
sewage.
 The first technology to deal with such pollution comes about with the
building of large networks of Cloacea’s (sewers) and Aqueducts to
manage sewage and bring in fresh water.
 By 80 AD laws were passed requiring water to be stored in the dry
season in order to be used for street and sewer cleaning.
Medieval Times
 1300 AD – The British begin to use coal in place of wood as fuel.
 1306 – King Edward I forbids coal burning while Parliament is in session.
 1350 – The Bubonic Plague decimates Europe, creating the first attempts
at enforcing public health.
 1388 – Parliament passes law forbidding throwing garbage into ditches,
rivers and lakes.
 1589 – The water closet is invented by Sir John Harrington, but due to
lack of sewers the idea didn’t catch on until 1778.
 1684 – John Evelyn refers to London as a suburb of Hell, rather
than an assembly of rational creatures, in reference to the air pollution
created by the burning of coal.
 1700 – 600 ships are now engaged in hauling “sea coal” from Newcastle
to London, as opposed to just two ships in 1650.
America and the Industrial Revolution
 1769 – Committee led by Benjamin Franklin attempts to regulate waste and
water pollution in Philadelphia.
 1783 – Benjamin Franklin encourages France and Germany to switch from
wood to coal, noting how it saved what was left of England’s forests.
 1824 – Jean Baptiste Joseph Fourier makes the first scientific reference to
global warming proposing that the sun’s heat is trapped by the atmosphere.
 1849 – Edwin Drake strikes Oil in Pennsylvania, creating Kerosene market.
 1854 – Daniel Halladay introduces the mechanical windmill, which will see
6 million in use in by the mid 1950’s.
 1870 – John D. Rockefeller incorporates the Standard Oil Company.
 1872 – President Grant signs the Yellowstone National Park Act making
Yellowstone America’s first National Park.
 1875 – Grant vetoes a bill protecting buffalo and other wildlife.

 1880 – First US municipal smoke abatement laws enacted aimed at
reducing air pollution from factories, railroads and ships.
 1881 – Samuel P. Langley leads expedition to Mt. Whitney to measure solar
heat and it’s absorption in the atmosphere, which later creates the basis for
the greenhouse theory.

doubling the use of coal and petroleum would lead to a 5 degree C (9F)
increase in average global temperatures.
 1916 – Woodrow Wilson establishes the National Park Service.
 1919 – Zion and Grand Canyon National Park’s are established.
 1921 – General Motors demonstrates a car powered by 30% alcohol.
Fourteen months later gasoline with tetraethyl lead is introduced by its
subsidiary Ethyl Corp. eliminating further research of alcohol for anti-knock.
 1937 – The term Greenhouse Effect is coined by Glen Thomas Trewartha,
when he describes the trapping of CO2 in the atmosphere and insulating
the earth like a pane of glass in a greenhouse.

The Future of the Environmental Movement
What impact does it have on you?
Global Warming
 Most scientists today agree that Global Warming is the single greatest threat
to our environment in the future.
 Since 1860, average global temperatures have increased 1.4 degrees F,
which is the single largest increase in the last 2000 years.
This figure was originally prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.
Global Warming con’t
 The main cause of this temperature rise is believed to be man-made carbon
dioxide emissions from the burning of fossil fuels. Fundamentally everything
we do in a modern society somehow impacts carbon emissions.
 Average carbon dioxide levels in the atmosphere have risen to 380 ppm,
which is the highest value in the last 650,000 years, which is the period for
which reliable data has been extracted from ice cores. It is last believed to
have been this high ~40 million years ago.
This figure was originally prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.
Global Warming con’t
 By the year 2100 average global temperatures will rise 2.5 to 10 degrees F
above the current average, assuming that nothing is done to curb the current
use of fossil fuels.
This figure was originally prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.
Global Warming Effects
Increased Heat Waves, Drought and Wildfires.
 In 2003 heat waves caused 20,000 deaths in Europe and 1,500 in India.
 In 2002 the Western US suffered the worst wildfire season in 50 years with
over 7 million acres burned.
 The 1999-2002 national drought was one of the three most extensive
droughts in the last 40 years.
This figure was originally prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.
Global Warming Effects con’t
Increased Storms and Loss of Ecosystem
 The number and intensity of tropical storms and
hurricanes has nearly doubled over the last 35 years.
It is expected that worldwide costs associated with
this increase in storms could total as much as 1.5
trillion dollars over the next 10 years.
 Recent studies indicate that 279 species of plants and
animals have already been effected by the increased
temperatures and up to a million species could be
affected by the year 2050.
 Increased carbon dioxide levels in the oceans are
predicted to reduce Ocean pH by up to 0.4 units
greatly impacting the worlds coral reefs – considered
to be the largest living organisms on the planet.
Global Warming Effects con’t
Melting Glaciers and Rising Sea Levels
 Since 1995 the Antarctic ice shelf has shrunk by 40%. In 2002 a section
of the size of Rhode Island collapsed in just three months. Loss of surface
ice leads to less reflection of the sun heats, resulting in further warming.
 Sea levels are predicted to rise by up to one meter by 2100, which is
expected to displace ~200 million people in Coastal areas.
The satellite photo at far left shows the Larson B ice shelf on Jan. 31, 2002. Ice appears as solid
white. Moving to the right, in photos taken Feb. 17 and Feb. 23, the ice begins to disintegrate. In
the photos at far right, taken Mar. 5 and Mar 7, note water (blue) where solid ice had been, and
that a portion of the shelf is drifting away. Photos: National Aeronautics and Space Administration
Global Warming Effects con’t
Climate Change
 Less understood is the effect of warming on climate change. Some
believe melting arctic ice could destabilize deep ocean currents through
the shutdown of the thermohaline circulation process, leading to abrupt
climatic shift in the opposite direction – in other words global cooling.
What can be done?
Methods in Use or Being Researched
 Reduce, Reuse, Recycle (Conservation) – Everything uses energy, so the
we conserve (water, waste, energy) the less fossil fuels will be burned.
 Shift from a carbon based economy to a alternative/renewable fuel
economy – Wind, Solar, Bio-based, Hydrogen, etc. (no carbon)
 Carbon Capture and Storage – which is essentially compressed CO2
emissions and safely storing as to not interact with the atmosphere.
 Carbon Sequestration – basically the opposite of carbon creation, i.e.
when plants utilize CO2 for photosynthesis. There are forms of artificial
sequestration already in use, but is expensive.
 Planetary Engineering – the kind of stuff that wins Academy Awards…
still in the realm of science fiction.
