Technologies that shrank the globe

The pace of globalization since the 20th century has been driven above all by technology. Advances in communication — the telephone, satellites, and above all the internet — allow information to travel the world instantly. Advances in transportation — jet aircraft, container ships, and highways — move people and goods faster and more cheaply than ever. Together these created a smaller, more connected world in which distant events, markets, and cultures interact in real time. This connectivity is the technological foundation on which economic and cultural globalization rest.

Green Revolution and medical advances

Technology reshaped human life directly. The Green Revolution introduced high-yield crops, fertilizers, and modern farming methods, dramatically increasing food production and helping feed a soaring world population — though it also raised concerns about environmental damage and inequality. Advances in medicine — vaccines, antibiotics, and improved sanitation — sharply reduced death from disease and helped drive an unprecedented population explosion, from about 1.6 billion in 1900 to over 6 billion by 2000. Longer lives and larger populations transformed societies worldwide.

The costs of connection

Technological change brought serious costs alongside its benefits. Industrial and consumer growth intensified environmental problems — pollution, deforestation, and climate change driven by greenhouse gases from fossil fuels. Rapid global travel also meant pandemics could spread with frightening speed, as diseases moved along the same networks that carry trade and tourists. And the digital revolution created a "digital divide" between those with access to new technologies and those without. Globalization’s connectivity, in short, spreads risks as readily as opportunities.

Worked example

Explain ONE way technological development contributed to global population growth in the 20th century. (SAQ-style reasoning)

1.Choose a specific development: advances in medicine (vaccines, antibiotics) and the agricultural Green Revolution.
2.Explain the mechanism: medical advances reduced death rates by preventing and treating disease, while the Green Revolution increased food supplies to feed more people.
3.State the effect: with fewer deaths and more food, populations grew rapidly, contributing to the explosion of world population from roughly 1.6 billion in 1900 to over 6 billion by 2000.

Answer: One way was through advances in medicine and agriculture. Vaccines, antibiotics, and better sanitation sharply lowered death rates, while the Green Revolution’s high-yield crops greatly increased food production. Together, fewer deaths and more abundant food allowed populations to grow rapidly, helping drive the twentieth century’s dramatic population explosion from about 1.6 billion to over 6 billion people.

Watch out

Globalization is not all upside. For every benefit — instant communication, more food, longer lives — note a cost: climate change, rapid pandemics, and the digital divide. Strong answers weigh both, rather than portraying technological change as purely positive.
