The modern revolution has had a positive impact on the world we know today, although it also has its negative drawbacks. The modern revolution is about the new forms of innovation, technology, ideas, energy sources and global exchange networks that have been generated over the last fifteen hundred years. While the rate of collective learning has accelerated and helped improve our lifestyles, including communication, transportation, and the production of goods, these have also led to a negative impact on our world.

Get an Original Essay Over the past 300 years, life expectancy, birth rates, and total population size have changed dramatically. According to Ronald Lee, professor of economics at the University of California, graph in text 01 “Population Trends” in Investigation 9, the age of life expectancy has increased by nearly 40 years and the size of our population has grown by less than 1 billion to 7 billion from 1700. to 2000s. While it is good that people can live longer, as our population continues to grow, the world must maintain it and keep up with our needs. Along with population growth, the Modern Revolution helped move people living rural lifestyles to live in cities with populations of more than 10 million people. Text 02 “Urban Population Growth” in Investigation 9 in Big History shows that “only 3% of the world's population lived in cities when the Modern Revolution began in 1800. For about 200 years, more than half of the world's population was urban” in a graphic from the United Nations publication. Urbanization and overall growth could add 2.5 billion people by 2050, with 90% concentrated in Asia and Africa. As stated earlier in the previous paragraph, it might be smart to take into consideration that our world might not be able to support that many people. Another positive effect that the modern revolution has on our world is the growth of literate and educated people. The United Nations Educational, Scientific and Cultural Organization in text 03 “Literacy and Education” in Investigation 9 states that only 10% or 120 million people in 1850 could read and write, but today almost 80% or 5.1 billion people are able to read and write. However, women are less literate than men, and most of the world's illiterate adults live primarily in South and Southwest Asia, East Asia and the Pacific, and Sub-Saharan Africa. Recently, literacy rates have increased by just over 10% in these areas. The last major positive effects that the modern revolution has on the world are its new inventions, discoveries and vaccines for disease prevention. Major inventions or discoveries made from 1800 to today become more complex over the years, especially from the 1950s to today, making our lives simpler and giving us the opportunity to do more things. The first effective vaccine was developed by Edward Jenner in 1796 to help prevent smallpox. Since then, more vaccines have been developed to fight serious diseases and save more lives. According to the graph modified by the National Centers for Disease Control in Text 05 “Vaccines and Diseases” of Investigation 9, the number of cases of smallpox, polio, measles and mumps decreased dramatically, some by 100% in 2010. However, the World Health Organization says that many children (up to 1.5 million) without these.
