  1. Humans and Nature:Ecological and Cultural Stages

  2. Humans vs. nature: Agricultural societies10,000-12,000 years ago Humans in nature: Early hunter-gatherers3 million years ago Humans in nature: Advanced hunter-gatherers1.5 million years ago Humans with nature: Sustainable societiesThe near future?? Humans vs. nature: Industrial societies1850 - present

  3. Early hunter-gatherers3 million years ago • Population densities: LOW • Energy sources: HUMAN MUSCLE POWER • Tools: PRIMITIVE (stone, bone, wood) • Effects on environment: MINIMAL Local effects on plant and animal populations due to over-harvesting

  4. Advanced hunter-gatherers1.5 million years ago • Population densities: LOW • Energy sources: HUMAN MUSCLE POWER, FIRE • Tools: PRIMITIVE (stone, bone, wood) • Effects on environment: LOW TO MODERATE • Local effects on plant and animal populations • Moderate effects due to mass killings of herd animals and use of fire to flush game

  5. Advanced hunter-gatherers1.5 million years ago “Pleistocene overkill”: • Pleistocene extinctions of certain large mammals may have been hastened by excessive hunting • E.g., Mammoths, mastodons, ground sloths in North America; certain primitive marsupials in Australia

  6. Advanced hunter-gatherers1.5 million years ago Primitive habitat management • Neolithic humans realized that burned-over areas attracted game (e.g., grazers to regenerating grasslands) • Used fire to manipulate habitat and draw in prey

  7. Agricultural societies10,000 – 12,000 years ago • Population densities: GENERALLY LOW, but -numerous VILLAGES (up to 500 people) -some TOWNS (up to 25,000 people) -a few CITIES / URBAN CENTRES • Energy sources: HUMAN MUSCLE POWER FIRE DOMESTIC ANIMALS WIND and WATER POWER in later phases

  8. Agricultural societies10,000 – 12,000 years ago • Tools: METAL, CERAMICS, GLASS • Effects on environment: MODERATE TO LOCALLY SEVERE Transition from nomadic or semi-nomadic to sedentary lifestyle Dawn of the NEOLITHIC REVOLUTION: the development of AGRICULTURE in the new stone age
