Information about 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, human induced disasters, environmentalists that have had a positive influence, and environmental legislation. |

Other events and periods

Holocene

10th millennium BC

::: — 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.

9th millennium BC

::: — 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.
::: — World population reaches 1 million.
::: — North America - The glaciers were receding and by 8,000 BC the Wisconsin had withdrawn completely.
::: — World - Inland flooding due to catastrophic glacier melt takes place in several regions.

8th millennium BC

7th millennium BC

: — Rising sea levels form the Torres Strait, separate Australia from New Guinea.
: — Increasing desiccation of the Sahara. End of the Saharan Pluvial period.
: — Associated with Pollen Zone VI Atlantic, oak-elm woodlands, warmer and maritime climate. Modern wild fauna plus, increasingly, human introductions, associated with the spread of the Neolithic farming technologies.
: — Rising sea levels from glacial retreat flood what will become the Irish Sea, separating the island of Ireland from the British Isles and Continental Europe.

6th millennium BC

  • Circa 5600 BC — According to the Black Sea deluge theory, the Black Sea floods with salt water. Some 3000 cubic miles (12,500 km³) of salt water is added, significantly expanding it and transforming it from a fresh-water landlocked lake into a salt water sea.
  • Circa 5500 BC — 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.
  • Circa 5000 BC — The Older Peron transgression, a global warm period, begins.
  • 5000 BC — Use of a sail begins. The first known picture is on an Egyptian urn found in Luxor.

4th millennium BC

3rd Millennium BC

  • 2900 BC — Floods at Shuruppak from horizon to horizon, with sediments in Southern Iraq, stretching as far north as Kish, and as far south as Uruk, associated with the return of heavy rains in Nineveh and a potential damming of the Karun River to run into the Tigris. This ends the Jemdet Nasr period and ushers in the Early Dynastic Period of Sumer cultures of the area. Possible association of this event with the Biblical deluge.
  • 2650 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.
  • 2600 BC — First artificial sewage systems constructed in the cities of Harappa and Mohenjo-daro of the Indus valley. There were networks of brick-lined sewage drains and outdoor flush toilets connected.
  • 2500 BC — Sahara becomes fully desiccated. Desiccation had been proceeding from 6000 BC, as a result of the shift in the West African tropical monsoon belt southwards from the Sahel. Subsequent rates of evaporation in the region led to a drying of the Sahara, as shown by the drop in water levels in Lake Chad. Tehenu of the Sahara attempt to enter into Egypt, and there is evidence of a Nile drought in the pyramid of Unas.
  • 2200 BC — Beginning of a severe centennial-scale drought in northern Africa, southwestern Asia and midcontinental North America, which very likely caused the collapse of the Old Kingdom in Egypt as well as the Akkadian Empire in Mesopotamia.

2nd millennium BC

  • 1900 BC — The Atra-Hasis Epic describes Babylonian flood, with warnings of the consequences of human overpopulation.
  • 1450 BCMinoan civilization in the Mediterranean declines, but scholars are divided on the cause. Possibly a volcanic eruption was the source of the catastrophe (see Minoan eruption). 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.
  • 1206 BC - 1187 BC — Evidence of major droughts in the Eastern Mediterranean. Hittite and Ugarit records show requests for grain were sent to Egypt, probably during the reign of Pharaoh Merenptah. Carpenter has suggested that droughts of equal severity to those of the 1950s in Greece, would have been sufficient to cause the Late Bronze Age collapse. The cause may have been a temporary diversion of winter storms north of the Pyrenees and Alps. Central Europe experienced generally wetter conditions, while those in the Eastern Mediterranean were substantially drier. There seems to have been a general abandonment of peasant subsistence agriculture in favour of nomadic pastoralism in Central Anatolia, Syria and northern Mesopotamia, Palestine, the Sinai and NW Arabia.
  • c 2000 BC-1000 BC - The Sarasvati River dries up. Desertification of the Thar Region begins.

1st millennium BC

  • 800 BC - 500 BC — Sub-Atlantic period in Western Europe. Pollen Zone VIII, sub-Atlantic. End of last Sea Level rise. Spread of "Celtic fields", Iron Age A, and Haalstadt Celts. Increased prosperity in Europe and the Middle East.
  • 500 BCRoman Republic, Cloaca Maxima (big sewer) is built in Rome by Etruscan dynasty of Tarquins. As Rome grows, a network of cloacae (sewers) and aqueducts are built.
: — World population reached 100 million[1].
  • 250 BCAshoka introduces animal welfare legislation in India
  • Circa 225 BC — The Sub-Atlantic began about 225 BC (estimated on the basis of radiocarbon dating) and has been characterized by increased rainfall, cooler and more humid climates, and the dominance of beech forests. The fauna of the Sub-Atlantic is essentially modern although severely depleted by human activities. The Sub-Atlantic is correlated with pollen zone IX; sea levels have been generally regressive during this time interval, though North America is an exception.
  • Circa 200 BCSri Lanka first country in the world to have a nature reserve, King Devanampiyatissa established a wildlife sanctuary

1st millennium AD

  • 100 to 400 — 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.

7th century

8th century

9th century

  • Circa 850 — Severe drought exacerbated by soil erosion causes collapse of Central American city states and the end of the Classic Maya civilization.

2nd millennium AD

15th century

  • 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.

18th century

  • 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. This event has been considered as the origins of the 20th century Chipko movement.
  • 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.
  • 1748Jared Eliot, clergyman and physician, writes Essays on Field Husbandry in New England promoting soil conservation.
  • 1762 to 1769 — Philadelphia committee led by Benjamin Franklin attempts to regulate waste disposal and water pollution.
