In the beginning…In the beginning…

~10,000 years ago the human population began to rise after the Neolithic Agricultural Revolution.

◦Humans settled to become farmers instead of local hunter-gatherers.

◦This meant managing local resources (food, water, fuel) sustainably around the settlement

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.

……laterlater

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.

1700’s1700’s

In 1700’s water pollution issues started being discussed and solutions were searched.

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.

Industrial RevolutionIndustrial Revolution

…With the start of industrial revaolution in the early 1800s

goods and services for nearly all was produced, but demanded the burning of large amounts of trees and coal.

Required large-scale mining.Land was cleared, natural waterways were

polluted, cities became crowded and smoky.

1800’s – 1900’s1800’s – 1900’s

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.

Sierra ClubSierra 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;

to use all lawful means to carry out these objectives.

1900’s1900’s

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.

Ralph Waldo EmersonRalph Waldo Emersonand Henry David Thoreauand Henry David Thoreau

Wrote about respect for the natural world.Described an almost mystical experience.Transcendentalists*.Not scientists.

*Transcendentalism is a religious and philosophical movement that was developed during the late 1820s and 1830sin the Eastern region of the United States.

Montreal Protocol (1989)Montreal Protocol (1989)

Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion.

Rio Earth Summit (1992)Rio Earth Summit (1992)The United Nations Conference on Environment and Development (UNCED), June 1992. It led to the Kyoto Protocol. The Convention on Biological Diversity was opened for signature.The Earth Summit resulted in the following documents:Rio Declaration on Environment and DevelopmentAgenda 21Convention on Biological DiversityForest PrinciplesFramework Convention on Climate Change (UNFCCC).

Both Convention on Biological Diversity and Framework Critics, however, point out that many of the agreements made in Rio have not been realized regarding such fundamental issues as fighting poverty and cleaning up the environment.

Kyoto Protocol (1997) Kyoto Protocol (1997)

Kyoto Protocol is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC), aimed at fighting global warming. The UNFCCC is an international environmental treaty with the goal of achieving "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system."

Participation in the Kyoto Protocol, as of June 2009, where dark green indicates the countries that have signed and ratified the treaty, grey is not yet decided and red is no intention to ratify.

1990’s to Present1990’s to Present

Debates continue around the world about environmental issues.

United Nations begins addressing global climate change and suggests solutions, but many countries do not want to comply.

Support grows for alternative energy sources such as sun & wind energy.

In 1997 the Kyoto Protocol was drafted. An agreement made under the UN 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.

Dust Bowl(1930 to 1936) Dust Bowl(1930 to 1936)

The Dirty Thirties was a period of severe dust storms causing major ecological and agricultural damage to American and Canadian prairie lands from 1930 to 1936 (in some areas until 1940). The phenomenon was caused by severe drought coupled with decades of extensive farming without crop rotation, fallow fields, cover crops or other techniques to prevent erosion.

Minamata (1956) Minamata (1956) Minimata disease was first

discovered in Minamata city, Japan in 1956. It was caused by the release of methylmercury in the industrial wastewater from the Chisso Corporation's chemical factory, which continued from 1932 to 1968. This highly toxic chemical bioaccumulated in shellfish and fish in Minamata Bay and the Shiranui Sea, which when eaten by the local populace resulted in mercury poisoning.

As of March 2001, 2,265 victims had been officially recognised (1,784 of whom had died) and over 10,000 had received financial compensation from Chisso. By 2004, Chisso Corporation had paid $86 million in compensation, and in the same year was ordered to clean up its contamination.

DDT (1962) DDT (1962) DichloroDiphenylTrichloroet

hane) is one of the most well-known synthetic pesticides. In 1962, American biologist Rachel Carson wrote Silent Spring. The book cataloged the environmental impacts of indiscriminate DDT use in the US and questioned the logic of releasing large amounts of chemicals into the environment The book suggested that DDT and other pesticides cause cancer and that their agricultural use was a threat to wildlife, particularly birds. It produced a large public outcry that led to a 1972 ban in the US.

Chernobyl Chernobyl disaster disaster (April (April 1986) 1986)

was a nuclear accident that occurred on 26 April 1986, at the Chernobyl Nuclear Power Plant in Ukraine (then part of the Soviet Union). It is considered the worst nuclear power plant accident in history .

The accident raised concerns about the safety of the nuclear power in general, slowing its expansion for a number of years.

It is estimated that there were 4,995 additional deaths, between 1991 -1998, among the approximately 60,000 most highly exposed people.

Set up of National Parks in Set up of National Parks in The UK (1949)The UK (1949)

The original ten National Parks of England and Wales were set up in the 1950s following an Act of Parliament in 1949. The purposes of the National Parks are:

1. To conserve and enhance the natural beauty, wildlife and cultural heritage of the area

2. To promote opportunities for the understanding and enjoyment of the Parks’ special qualities by the public

Set up of National Parks in the Set up of National Parks in the USA (1872 to 2004)USA (1872 to 2004)

The United States has 58 protected areas known as national parks, which are operated by the National Park Service.

The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."

Ozone Holes (Late 1970s to Ozone Holes (Late 1970s to Present)Present)Holes in the Ozone layer describes two

distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total volume of ozone in Earth's stratosphere since the late 1970s, and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole. In addition to this well-known stratospheric ozone depletion, there are also tropospheric ozone depletion events, which occur near the surface in Polar Regions during spring.

Bhopal disaster (December 1984)Bhopal disaster (December 1984)

The Bhopal disaster or Bhopal Gas Tragedy is the world's worst industrial catastrophe. It occurred on the night of December 2-3, 1984 at the Union Carbide pesticide plant in Bhopal, India.

A leak of methyl isocyanate (MIC) gas and other chemicals from the plant resulted in the exposure of several thousands of people. Estimates vary on the death toll. The official immediate death toll was 2,259 and the government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release. Other government agencies estimate 15,000 deaths.

Exon Valdize (March 1989)Exon Valdize (March 1989) The Exxon Valdez oil spill

occurred in Prince William Sound, Alaska, on March 24, 1989, when the Exxon Valdez, an oil tanker bound for Long Beach, California, struck Prince William Sound's Bligh Reef and spilled 260,000 to 750,000 barrels (41,000 to 119,000 m3) of crude oil. It is considered to be one of the most devastating human-caused environmental disasters ever to occur in history.. The oil, originally extracted at the Prudhoe Bay oil field, eventually covered 1,300 miles (2,100 km) of coastline, and 11,000 square miles (28,000 km2) of ocean
