The growth of our global population has made the expansion of technology a necessity, to sustain life as we know it.
Prior to the Industrial Revolution (1750), most of the global population operated independently in an agrarian (farming) society.
Our Dependence on Technology Innovations

The Industrial Revolution brought about the movement of large segments of people from the rural areas to the cities in search of employment.
This brought about dramatic changes to the structure of society and also drove (and continues to drive) major technological innovations.
Our Dependence on Technology Innovations

How have technological solutions impacted the manufacturing process?
A. Positive impact of automation on manufacturing efficiency and cost reduction
●Having the capacity to produce large volumes of product at lower cost than handcraft workers
●Programmable robotic processes allow for greater standardization and higher product quality
B. Negative impact of automation on human labor ●Automation allows non-stop production with fewer people; Production not impacted by human limitations (illness, injury,
fatigue)
●Automated processes have made many manual tasks obsolete and does not carry the additional cost of human labor (medical benefits, labor negotiations, training, etc.)
C. Increased requirements for a more skilled and educated workforce 12

Risks and Benefits of engineering activities
A. Benefit 1: Efficient manufacturing processes (see notes)
B. Benefit 2: Safe, efficient transportation and construction systems (see notes)
13Copyright © Texas Education Agency, 2012. All rights reserved
Risks and Benefits of engineering activities (continued)
C. Benefit 3: Safe, efficient food production, water distribution and waste management
14Copyright © Texas Education Agency, 2012. All rights reserved
D. Risks: Increased energy consumption and waste creation
● Energy consumption and pollution since the Industrial Revolution has increased exponentially each decade.
The growth of industrialization in third world countries has compounded the problem. We are in danger of
consuming and or contaminating major portions of our non-renewable resources.

A. Managing environment accidents, pollution and natural resource consumption (mining, petroleum and natural gas production, etc. )
B. *The impact of a mobile population
C. Positive management of growth within the key technology disciplines to reduce the impact on our environment
The Environmental Impact of the
engineering process

The Environmental Impact of the engineering process (continued)
D. The impact of a mobile population
● The relocation of the auto industry. (see notes)
●The impact on the communities left behind. (see notes)
E. Positive management of growth within the key technology disciplines to reduce the impact on our environment
● Long term, environmental planning will be necessary if future generations are to prevent this cycle from re-occurring .
