Humans will become __________ due to too much desire for automation. There is a big chance that robots will replace humans in the future.

Who created the 4 stages of Technology?
Proto, Classical, Modern and Post Modern Technology
What are the 4 stages of Technology?
PROTO-TECHNOLOGY
focuses on the time when early tools were developed before civilization.
First
What does the word “proto” mean?
CLASSICAL TECHNOLOGY
concentrates on the rise of agricultural technologies & the establishment of communities & cities that enabled the survival of civilization.
CLASSICAL TECHNOLOGY
Humans learned how to be sustainable, they became capable of producing their own resources due to the volution of tools
MODERN TECHNOLOGY
fuelled by science concepts & principles which date back about 500 years ago.
The 21st century, after the industrial revolution.
When did Modern Technology arise?
POST MODERN TECHNOLOGY
replaces naturally occurring products with technologically developed ones. Some highly toxic (petroleum & its derivatives)
Jet engine
Gasoline-powered automobiles
Bakelite
Synthetic Fertilizers Plastics
polyvinyl chloride
What does PVC stand for?
polychlorobiphenyl
What does PCB stand for?
Chlorofluorocarbons
What does CFC stand for?
MODERN TECHNOLOGY
treats everything as a resource
GRADUALLY:
Usual course of life as individuals age & is replaced with more adaptive species.
Ecological Niche
it is the position or role of species in an ecosystem. It describes both the range of conditions necessary to the persistence of species)
SUDDENLY
The disappearance of an ecological niche due to abrupt changes man has inflicted in the ecosystem because of mindless hunger for innovation or natural phenomena
Chlorofluorocarbons (CFCs)
are actually safe to use, it can be seen in aerosol sprays, refrigerators and air conditioners but it is not safe for the environment.
O3 or 3 atoms of oxygen that is bonded together.
Ozone layer is made of ozone formula called
OZONE LAYER DEPLETION DUE TO CFCS
When CFCs get into the atmosphere, its molecule separates the 3 atoms of oxygen and sticks to the oxygen. As a result the ozone molecule is destroyed; more carbon dioxide gets trapped leading to global warming.
The Montreal protocol
is the first protocol that all countries agreed upon, it bans the use of CFCs across all nations. The government expects that by the 2050, the ozone layer will recover due to the banning of CFCs
CLIMATE CHANGE
climate scientist have predicted that an average increase of 2 degrees will be experienced in 2050. This will have drastic change in the weather condition across the globe. Ex: 2012 “Pablo”, 2013 “Yolanda”
Fossil Fuel
is actually sustainable; it is one of the primary contributors of greenhouse gases once they are burned.
Nuclear power plant
are plants that have nuclear reactors. They are acting as a source of energy, it is capable of creating large amount of energy with very little resources but it is very hazardous if not managed properly.
Chernobyl, Ukraine
became highly radioactive due to a nuclear leak in one of the nuclear reactors. This is because of human errors and technical lapses, thousands of people were exposes to carbon radiation
Hiroshima Nagasaki
it happened in World War II in August 6, 1945. was purposely bombed, it is known that it caused an estimated of 140,000 deaths by the end of 1945
Fukushima Daiichi Nuclear Power Plant –
Due to the Great East Japan earthquake, the nuclear power plant experienced a meltdown.
Great Pacific Garbage Patch Northern Pacific Ocean,
it is an island that is made up of plastics that bonded together and formed an island. It is known to contain that highest decomposed plastic on earth, killed thousands of marine animals and known to enter our food chain
Algal Bloom or Eutrophication
decreases the oxygen in the water and marine animals die due to low levels of oxygen due to high concentration of nitrogen and properous that increases the algae in water
PETROLEUM-BASED FERTILIZER
it has high content of nitrogen of prosperous which is god for the plants but not for the soil.
HABITAT DESTRUCTION
a result of land alteration, deforestation and other agriculture practices
