History of the Environmental Movement
2
Earliest Accounts of Environmental Concerns
  • Air and water pollution was not a much of a
    concern, though places like the Roman Empire were
    known to have sewage in the streets.
  • The cutting of timber for building was an early
    concern in places such as Babylon, Greece, Italy,
    Phoenicia.
  • Soil conservation was practiced by civilizations
    in China, India, and Peru.

Earliest Accounts of Environmental Concerns
continued
  • As countries became more developed, sanitation
    became a problem. The best example is Europe
    during the Middle Ages and the outbreak of the
    Bubonic Plague.
  • Forests were also disappearing more and more as
    the need for timber increased.

4
1700s
  • Ben Franklin began noting water pollution issues
    and pushed for a solution.
  • A correlation between population and resources
    was made and brought to light that as one
    increases, the other decreases.
  • The use of more coal led to more air pollution.

5
1800s 1900s
  • The impact of water born diseases became a big
    concern as well as working conditions in
    factories and industry.
  • A push was also made to start preserving
    wilderness areas. Teddy Roosevelt Gifford
    Pinchot suggested forests be used wisely.
  • The Sierra Club formed during this time.

6
Sierra Club
  • To explore, enjoy, and protect the wild places of
    the earth To practice and promote the
    responsible use of the earth's ecosystems and
    resources To educate and enlist humanity to
    protect and restore the quality of the natural
    and human environment and to use all lawful
    means to carry out these objectives.

7
1900s
  • Impacts of the burning of chemicals and
    processing of synthetic materials is publicized.
  • Air pollution is seen as a problem. In 1957,
    increased levels of CO2 was documented and was a
    concern.

8
1960s 1970s
  • The harmful effects of leaded gasoline is
    presented before Congress.
  • Silent Spring -1966-book by Rachel Carson-stated
    that uncontrolled pesticide use (DDT) led to the
    deaths of animals and especially birds, but also
    humans. Its title was meant to evoke a spring
    season in which no bird songs could be heard,
    because they had all died from pesticides.
  • Cuyahoga River -1969-oil chemicals burn in
    Ohio, sparking a big environmental movement.

9
1970s-1980s
  • EPA is established and major environmental laws
    are passed such as the Clean Air Act Clean
    Water Act.
  • Catalytic converters are put on cars.
  • The effects of toxic dumps comes to light after
    the Love Canal incident. (1978)
  • Nuclear power is questioned after a minor
    accident at Three Mile Island. (1979)
  • First major energy crisis over supply of oil.
    (1973)

10
Love Canal Incident
  • Love Canal is a neighborhood in New York which
    became the subject of national and international
    attention and controversy following the discovery
    of 21,000 tons of toxic waste buried beneath the
    neighborhood.

11
Three Mile Island Incident
  • Three Mile Island is an island in the Susquehanna
    River near Harrisburg Pennsylvania.
  • The Three Mile Island accident of 1979 was the
    most significant accident in the history of the
    American commercial nuclear power generating
    industry. It resulted in the release of a
    significant amount of radioactivity, an estimated
    43,000 curies of radioactive krypton

12
1980s 1990s
  • 1980s Major Disasters
  • Chernobyl
  • Exxon Valdez- Largest oil spill to date.
    Happened in the Prince William Sound in the Gulf
    of Alaska
  • Bhopal poisoning - 27 tons of lethal gases leaked
    from Union Carbide Corporation's pesticide
    factory in Bhopal, India. It was the worst
    chemical disaster in history.
  • Ozone depletion taken seriously in 1987.
  • Global Climate change becomes more of a concern.

13
Chernobyl
  • Chernobyl WAS a city in northern Ukraine
  • The Chernobyl disaster was a nuclear reactor
    accident in the Chernobyl Nuclear Power Plant. It
    was the worst nuclear power plant accident in
    history resulting in a severe release of
    radioactivity into the environment following a
    massive power excursion which destroyed the
    reactor.
  • Two people died in the initial steam explosion,
    but most deaths from the accident were attributed
    to fallout

15
1990s to Present
  • Debates continue in our government and around the
    world about environmental issues.
  • United Nations begins addressing global climate
    change and suggests solutions, but many countries
    do not want to comply.
  • Clinton sets aside 58 million acres of forest
    wilderness to be protected or managed.
  • Support grows for alternative energy sources such
    as wind energy.
  • In 1997 the Kyoto Protocol was drafted.
  • An agreement made under the United Nations
    Framework Convention on Climate Change (UNFCCC).
    Countries that ratify this protocol commit to
    reducing their emissions of carbon dioxide and
    five other greenhouse gasses, or engaging in
    emissions trading if they maintain or increase
    emissions of these green house gases.

16
Development of Alternative Energy
  • Deemed more important due to rise of fossil fuel
    costs.
  • Automotive companies spending more money to
    develop gas saving cars.
  • More efforts being made to develop solar, wind,
    biofuel, and hydrogen fuels.
  • Wind power is the fastest growing energy source.
