(38 cards)
This focuses on the time when early tooks were developed before civilization
Proto-technology
The earliest stages of technological development, specifically before the rise of civilization and complex societal strucutures
Proto-technology
It encompasses the period of tool development by early humans, often consideered to be between one and two million years ago
Proto-technology
This era is characterized by the creation and use of basic tools made from natural matersial like stone, woord, and bone
Pro-technology
This concentrates on the rise of agricultural technologies and establishment of communicties and cities that enabled the suvival of civilazation
Classical Technology
Traditional, non-digital tools and materials used in education and everyday life, often before the widespread adoption of computers and digital devices
Classical technology
It’s characterized by sophisticated products, services, and infrastructures resulting from rapid progress in science, engineering, and skills
Modern technology
Aims to improve efficiency and convenience across all areas of life, including business, healthcare, and everyday activities
Modern technology
This replaces naturally occurrind products with technologically developed ones
Post modern technology
Examples:
-gasoline-powered automobiles
- jet engines
- plastics
- chlorofluorocarbons
- synthetic detergents
-nylon
Post modern technology
What are the 4 stages of technology by Schultz (2016)
- Proto-technology
- classical technology
- modern technology
- post modern technology
what are the two scenarios of extinction
- Usual course of life as individuals age and replaced by other species more adapted to the changes of the world
- DIsappearance of the ecological niche due to the abrupt changes man has inflicted in the ecosystem
______ age and replaced by other species more adapted to the changing world
Usual course of life as infividuals
______ due to the abrupt changes man has inflicted in the ecosystem
Disappeance of the ecological niche
Complete disappearance of species from the earth
Extinct
_____ is the termination of an organism by the death of its last member
extinction
Extinct usually occurs one species at a time
Background extinction rate
5 events in Earth’s histoery that killed off massive numbers of species at once
Mass extinction events
____ all species went extinct at one time
50-95%
Humans are causing the sixth mass extinction event
- Population growth
- Development
- Resource depletion
What is CFC?
Chlorofluorocarbons
CFC destroyed the ozone layer that protects the planet from the UV radiation from the sun
Ozone layer depletion through chlorofluorocarbons
Releasing greenhouse gases, primarily carbon dioxide, into the atmosphere
Usage of fossi lfuel to global warming and climate change
______ can lead to widespread nuclear contamination through the dispersal of radioactive fall out and the long-term environmental effects of nuyclear explosions
Nuclear war and nuclear contamination
