Globalization and the 21st Century Study Guide

Globalization and Historical Connectivity

• Globalization is the defining characteristic of the 21st century.
• The concept of interconnectedness has evolved throughout history:     - Early stages involved smaller-scale trade via the Silk Roads, the Trans-Saharan Trade Route, and the Indian Ocean Trade Basin.     - These routes connected Afro-Eurasia, which includes Africa, Europe, and Asia.     - Afro-Eurasia is treated as a single connected unit in historical terms.
• True globalization began with the Columbian Exchange when the Old World met the New World.
• Despite modern clean energy technologies, the demand for petroleum has never decreased due to its reliability and the global infrastructure built around it.

Scientific Discoveries and the Big Bang

• Scientific discoveries are a major subtopic of globalization.
• The Big Bang Theory:     - This is the scientific theory regarding the creation of the universe and the Earth.     - It posits that a major astrological event gave rise to the universe millions or billions of years ago.     - Life started from single-celled organisms.     - Scientists theorize that the Earth is approximately $4 \times 10^{9}$ years old.

The Evolution of Communication Technology

• Communication has shifted dramatically from the period of $1200$ to $1450$.     - Early communication was primarily verbal and facilitated through trade routes.     - Inner-civilization contact was maintained by diplomatic travelers such as Marco Polo or Ibn Battuta on the Trans-Saharan trade route.
• 21st-century developments:     - The discovery of radio, light waves, and sound waves led to cell phone technology.     - Pagers (beepers) were common in the late 1990s; users would text a phone number to a pager, prompting a callback. Emergency room doctors still use this technology.     - Nokia was a dominant brand in the early 2000s; the speaker recalls getting their first cell phone around $2002$ or $2003$.
• Mass Media and the Internet:     - Television developed in the late 20th century, leading to mass media.     - Satellites were developed as part of the Cold War arms race and the general race for technology between superpowers.     - The Space Force (created under President Trump and maintained by President Biden) exists to protect vital satellite infrastructure rather than for "Star Wars"-style combat.     - The Internet became prominent in the 1990s through dial-up connections (AOL, Yahoo) using physical phone lines and wall plugs.

Medical Breakthroughs and Disease Eradication

• Medical breakthroughs in the 21st century have saved millions of lives through vaccines, treatments, and cures.
• Historically deadly diseases:     - Tuberculosis (TB): Studied by Louis Pasteur.     - Polio: Almost eradicated globally; famously affected President Franklin D. Roosevelt.     - Tetanus: Known as "lockjaw." It could be contracted by simple injuries, such as stepping on a dirty nail or getting a splinter. The speaker’s great uncle died from lockjaw caused by a splinter as a child.
• Cancer Treatment:     - Chemotherapy and radiation treatment did not exist until the 1960s or 1970s.     - Today, there is approximately a $60\%$ success rate for certain cancers.

Energy Sources and Production

• Nuclear Energy: A clean energy source that produces significant power for many countries. Despite associations with atomic bombs, it is increasingly being reintroduced by countries like the United States.
• Fossil Fuels (Petroleum/Gasoline):     - Usage exploded at the end of the 19th century.     - Petroleum is formed from ancient living organisms (animals and trees) over millions of years.     - Despite 1970s predictions that petroleum would run out by the 1990s, current reserves are estimated to last at least another $100$ years.
• Renewable Energy: Wind, thermal, and solar energy are being developed as renewable alternatives since petroleum is not infinite.

Transportation and Global Commerce

• Faster production and transportation are modern enhancements of the Industrial Revolution.
• Airplanes and Automobiles:     - Global travel that once took months (e.g., crossing the Atlantic by boat) now takes hours.     - A flight from Boston to London takes approximately $5$ hours.     - It is possible to fly anywhere in the world in approximately $16$ to $17$ hours.
• Economic Impact:     - Global commerce allows products to be sourced from anywhere.     - China has become an industrial hub because Western companies outsource manufacturing there to take advantage of cheap labor (approximately $1.00 USD per day).

The Green Revolution and Population Trends

• The Green Revolution refers to massive increases in agricultural production in the 21st century, not renewable energy.
• Key Factors:     - Use of chemical fertilizers to increase food supply.     - Genetically Modified Organisms (GMOs): These make crops resistant to drought, pests, and diseases. For example, natural apples are very small, but GMOs combined with other treatments create much larger fruit.
• Global Population:     - The global population is approximately $8 \times 10^{9}$ people.     - This is a significant increase from the $3 \times 10^{9}$ or $4 \times 10^{9}$ people at the beginning of the 20th century.     - Food production has successfully kept pace with this growth.

Social Changes and Global Migration

• The world is categorized into developed and developing nations:     - First World (Developed): Rich countries like the United States, Japan, and most of Europe.     - Second World: Countries like Mexico, which are no longer extremely poor but still developing.     - Third World (Developing): The poorest countries, such as Haiti, Somalia, and Ethiopia.
• Migration and Brain Drain:     - High population growth in developing countries puts pressure on people to migrate to first-world nations for better lives.     - "Brain Drain": The smartest individuals from poor countries leave for higher wages in Europe or the U.S., which inadvertently keeps the poor countries poor.

Women’s Rights and Demographic Shifts

• Feminism: The belief that women are equal to men economically, socially, and politically.
• Progress in the 20th and 21st Centuries:     - Women gained the right to vote, entered the workforce, and began demanding political office.     - The 20th century is often viewed as the "century of women" due to the massive gains in equality.
• Fertility and Birth Control:     - Access to birth control (contraception and abortion) in developed countries has caused fertility rates to drop.     - In contrast, developing countries have much higher birth rates, necessitating migration to wealthier countries to fill labor needs.

Global Culture and Economic Shifts

• American Culture: Influences the world via music (e.g., Tupac’s "California Love" is known globally) and restaurants (e.g., KFC is highly popular in Japan with five-story locations).
• Asian Influence: Korean entertainment (K-Dramas, K-Pop) and dance groups are now globally prominent.
• Economic History:     - Started with economic imperialism by industrialized Western nations.     - Japan, Hong Kong, and Korea challenged Western superiority through technology and manufacturing.     - Japan’s rise traces back to the Meiji Restoration.     - Hong Kong’s development was spurred by British colonization after the Opium Wars in the 1700s.     - Toyota and Honda (Japan) are among the most popular car brands globally.
• International Corporations: Entities like McDonald's (called "Mackey's" in Britain) seek global markets. For example, McDonald's in India does not serve beef or pork, focusing instead on items like the McFish to maintain profitability in diverse markets.

Political Changes and Movements

• Civil Rights Movements:     - Mahatma Gandhi led movements in India.     - In the U.S., movements involved Black Americans (descendants of victims of the Triangle Trade), Latino Americans, and Native Americans (notably in the 1970s).     - Anti-Apartheid movement in South Africa: Black people (three-quarters of the population) were barred from political office until civil rights were demanded.     - Nonviolent protest, championed by Gandhi and Martin Luther King Jr., became a model for the 20th century.
• Regional Conflicts and Resistance:     - Northern Ireland: Split between the Protestant North (loyal to Britain) and the Catholic South. The Irish Republican Army (IRA) used terrorism (e.g., blowing up garbage cans) in the 1970s and 80s to resist British rule.     - Arab Spring (C. 2011): Led to political shifts in North Africa and the Middle East.     - Theocracies: Countries like Tunisia, Syria, Libya, and Iran shifted toward Islamic governments. Iran's transition occurred in 1979. Recent protests in Iran (January 2023) led to the government reportedly shooting approximately $30000$ people.     - Israel: Established as a Jewish state by the British after WWI, gaining prominence after WWII and the Holocaust. This led to ongoing conflict with neighboring Arab populations who already inhabited the land.
