Timeline of environmental events

Encyclopedia : T : TI : TIM : Timeline of environmental events


The timeline of environmental events is a historical account of events that have shaped humanity's perspective on the environment. This timeline includes some major natural events, man-made disasters, environmentalists that have had a positive influence, and environmental legislation.

Earlier Events and Periods

::: — Bering Sea: Land bridge from Siberia to North America sinks.
::: — North America: Long Island becomes an island when waters break through on the western end to the interior lake
::: — Homo floresiensis, the human's last known surviving close relative, becomes extinct.
::: — World: Sea levels rise abruptly and massive inland flooding occurs due to glacier melt.
  • Circa 9700 BC — Lake Agassiz forms.
  • Circa 9600 BC — Younger Dryas cold period ends. Pleistocene ends and Holocene begins. Paleolithic ends and Mesolithic begins. Large amounts of previously glaciated land become habitable again.
  • Circa 9500 BC — Ancylus Lake, part of the modern-day Baltic Sea, forms.
  • ::: — Antarctica - long-term melting of the Antarctic ice sheets is commencing
    ::: — Asia - rising sea levels caused by postglacial warming
    ::: — World - Obliteration of more than 40 million animals about this time
    ::: — North America - The glaciers were receding and by 8,000 B.C. the Wisconsin had withdrawn completely.
    ::: — World - Inland flooding due to catastrophic glacier melt takes place in several regions

    ::: — Beginning of the desertification of north Africa, which ultimately lead to the creation of the Sahara desert. It's possible this process pushed some natives into migrating to the region of the Nile in the east, thereby laying the groundwork for the rise of Egyptian civilization.

    • 2700 BCSumerian epic of Gilgamesh describes vast tracts of cedar forests in what is now southern Iraq. Gilgamesh defies the gods and cuts down the forest, and in return the gods say they will curse Sumer with fire (or possibly drought). By 2100 BC, soil erosion and salt buildup have devastated agriculture. One Sumerian wrote that the "earth turned white." Civilization moved north to Babylonia and Assyria. Again, deforestation becomes a factor in the rise and subsequent fall of these civilizations.
    :: — Some of the first laws protecting the remaining forests decreed in Ur.

    • 1500 BCSoil erosion is both a consequence of growth and a cause of collapse of Central American city -states.
    • 1450 BCMinoan civilization in the Mediterranean declines, but scholars are divided on the cause. Possibly a volcanic eruption was the source of the catastrophe. On the other hand, gradual deforestation may have led to materials shortages in manufacturing and shipping. Loss of timber and subsequent deterioration of its land was probably a factor in the decline of Minoan power in the late Bronze Age, according to John Perlin in A Forest Journey.


    • 100AD to 400AD — Decline of Roman Empire may have been partly due to lead poisoning, according to modern historian and toxicologist Jerome Nriagu. Romans used lead acetate ("sugar of lead") to sweeten old wine and turn grape pulp into a sweet condiment. Usually the acidic wine or pulp was simply left in a vat with sheets of lead. An aristocrat with a sweet tooth might have eaten as much as a gram of lead a day. Widespread use of this sweetener would have caused gout, sterility, insanity and many of the symptoms which were, in fact, present among the Roman aristocrats. High levels of lead have been found in the bones of aristocratic Romans. Far more than simply using lead pipes or lead utensils, the direct consumption of lead-sweetened wine and foods created serious and widespread lead poisoning among upper-class Romans.

    • 1347 to 1350s — Bubonic plague decimates Europe, creating the first attempts to enforce public health and quarantine laws.
    • 1366 — City of Paris forces butchers to dispose of animal wastes outside the city (Ponting); similar laws would be disputed in Philadelphia and New York nearly 400 years later.
    • 1388Parliament passes an act forbidding the throwing of filth and garbage into ditches, rivers and waters. City of Cambridge also passes the first urban sanitary laws in England.

    • 1420 to 1427, Madeira islands : destruction of the laurisilva forest, or the woods which once clothed the whole island when the portuguese settlers decided to clear the land for farming by setting most of the island on fire. It is said that the fire burned for seven years.

    • 1546 — Italian physican Girolamo Fracastoro outlines theory of contagious disease. He reasoned that infectious diseases could be passed on in 3 ways: simple contact, indirect contact, and minute bodies over distance through the air.
    • 1560 to 1600 — Rapid industrialization in England leads to heavy deforestation and increasing substitution of coal for wood.

    • 1640 — Isaac Walton writes The Compleat Angler about fishing and about conservation.
    • 1662John Graunt publishes a book of mortality statistics compiled by parish and municipal councils in England. Although the numbers are inaccurate, a start was made in epidemiology and the understanding of disease and public health.
    • 1690 — Colonial Governor William Penn requires Pennsylvania settlers to preserve one acre of trees for every five acres cleared.

    • 1700 — Some 600 ships are engaged in hauling "sea coal" from Newcastle to London, an enormous increase compared to 1650, when only two ships regularly carried sea coal. Rapid industrialization and the demand for iron and naval supplies has stripped England's forests.
    • 1711Jonathan Swift notes the contents of London's gutters: "sweepings from butchers' stalls, dung, guts and blood, drowned puppies, stinking sprats, all drenched in mud..."
    • 1720 — In India, hundreds of Bishnois Hindus of Khejadali go to their deaths trying to protect trees from the Maharaja of Jodhpur, who needed wood to fuel the lime kilns for cement to build his palace.
    • 1739Benjamin Franklin and neighbors petition Pennsylvania Assembly to stop waste dumping and remove tanneries from Philadelphia's commercial district. Foul smell, lower property values, disease and interference with fire fighting are cited. The industries complain that their rights are being violated, but Franklin argues for "public rights." Franklin and the environmentalists win a symbolic battle but the dumping goes on.
    • 1748 — Jared Eliot, clergyman and physician, writes Essays on Field Husbandry in New England promoting soil conservation.
