The document discusses how ancient humans interacted with and impacted their environment during different periods of history. It describes how early humans in the Paleolithic period lived nomadic lifestyles as hunter-gatherers and had little impact on the environment. It then discusses how agriculture and population growth in the Neolithic period led to increased environmental impacts including deforestation and extinction of large animal species. Finally, it notes how the Industrial Revolution brought about widespread ecological changes through activities like mining, burning of fossil fuels, and urbanization.

20. Our early human ancestors are
thought to have
come into existence about
6 million years ago.

21. Several sets of skeletons have been unearthed by archaeologists, such as
the:
Australopithecus
Homo habilis
africanus
Homo ergaster
Human population density was very
low, around only one person per square
mile, and they were generally NOMADIC.

23. This period was also called
the
This was the period when
chipped-stone tools were first
used.

24. What was their
lifestyle like during
the Paleolithic
Period?

25. - the subsistence strategy employed by ancient
human societies
Humans hunted
wild animals for meat
and gathered
food, firewood, and
materials for their
tools, clothes, or shelters.

26. Ancient people used
fire:
• to herd and hunt game
• to deflect predators
• to provide warmth
• to encourage the
growth of vegetation
that would attract
grazing animals

27. Paleolithic humans enjoyed an
abundance of leisure time
unparalleled in both Neolithic
farming societies and modern
industrial societies.

28. The process of blade toolmaking, developed about 40,000 years ago, involved several steps of
production. (1) Using a palm-sized hammerstone, the toolmaker created a flat platform by
knocking off the top of a larger stone. (2) Using a wooden hammer and a piece of antler or
bone, the toolmaker struck down on the edge of the platform, knocking off several long
bladelike pieces around the perimeter. (3) Again using a piece of antler or bone, the toolmaker
retouched the blade flake by removing smaller flakes to create a finished tool. Some examples
of different types of blade tools appear to the right.

29. Stone age people
refined their killing
technologies.

30. Clovis points are named
after Clovis, Mexico
where they were first
discovered.

31. Stone age people refined their killing technologies.
 The Clovis point is a flaked,
bifaced projectile whose
length is more than twice its
width.
 Clovis points were attached to
spears and were used to hunt
game.

32. was a period in the development of
human technology, and is considered
the last part of the Stone Age.

33. Environmental conditions of this period

35. During most of the
Neolithic age, people
lived in small tribes.
In the neolithic, mud
brick houses started
appearing that were
coated with plaster.

36. The emergence of agriculture and farming
grew appreciation of nature through ritual,
religion, and art.

38. began nearly about 1,000,000 to 500,000 years ago.

40. Archaeologists believe that
many large North American
animal species, such as the
giant deer, woolly rhino, and
mammoth disappeared.

41. Before, 2.5 sq. km of wildlife and
vegetation were adequate for the
survival of two people. But since
population grew, more pressure
was placed on animal populations
to satisfy human food
requirements.
And since these animals are
large and could not escape
quickly, they were the easiest to
hunt.

44. Simplification of Ecosystems. Wild
species began to be replaced by fewer
cultivatable crops.
Increase of Human Population
Growth. Increased yields through
greater control over available foodstuffs
helped improve human health, increasing
the human population.

45. • Irrigation systems were clogged with salt.
• Deforestation (the removal of trees from an
area without adequate replanting) and
Siltation (the buildup of sand and salt in
waterways) were also problems.
• It caused civilizations such as Mesopotamia
to collapse.

46. …began with population increase, from
36 million to 80 million in 300 years
(1000-1300)

47. Exploitation of
environment and natural
resources
 More forested lands were cleared for
agriculture, more animals killed for food, and
more minerals exploited

48. Europe initiated its second phase of
expansion in the
Europeans were running
out of land, but they still
wanted to enlarge their
empires. They began
searching for and
colonizing other lands
outside Europe.

49. Industrialization and urbanization
have revolutionized human life and
brought about far-reaching
ecological changes.

50. Mining: loss of vegetation and topsoil,
erosion, water pollution and
acid/toxic drainage.
Burning of coal: emits carbon dioxide and
sulphur dioxide.
Burning of oil: air pollution and health
problems
