Topic 9.1 Advances in Technology and Exchange After 1900
Learning Objective
Explain how the
development of new
technologies changed
the world from 1900
to present
Historical Developments
New modes of communication—including radio
communication, cellular communication, and the
internet—as well as transportation, including air
travel and shipping containers, reduced the
problem of geographic distance.
Energy technologies, including the use of
petroleum and nuclear power, raised productivity
and increased the production of material goods
More effective forms of birth control gave women
greater control over fertility, transformed
reproductive practices, and contributed to
declining rates of fertility in much of the world
The Green Revolution and commercial
agriculture increased productivity and sustained
the earth’s growing population as it spread
chemically and genetically modified forms of
agriculture.
Medical innovations, including vaccines and
antibiotics, increased the ability of humans to
survive and live longer lives.
1. Choose one new mode of communication and explain how it reduced the
problem of geographic distance.
Cellular communication reduced geographic distance by making
communication instant even from different sides of the world.
2. Choose one new mode of transportation and explain how it reduced the
problem of geographic distance.
Air travel reduced the problem of geographic distance because it made
travel faster for long distances.
3. Choose one new energy technology and explain how it raised productivity
and the production of material goods.
Nuclear power raised productivity and the production of material goods by
allowing for power to be created in an easy and efficient way.
4. Explain the role of birth control in creating more opportunities for women in
the 20th century.
Birth control created more opportunities for women in the 20th century by
allowing women to have the choice on whether or not they want to bare a
child.
