Key Concept 6.1 Science and the Environment
I. Researchers made rapid advances in science that spread throughout the world, assisted by the development of new technology.
A. New modes of communication and transportation virtually eliminated the problem of geographic distance.
As the phone was invented by Edison early in the 19th, it revolutionized the world. Planes and cars changed methods of transportation. The Internet sped up communication and further connected the global world.
B. New scientific paradigms transformed human understanding of the world (such as the theory of relativity, quantum mechanics, the Big Bang theory or psychology).
C. The Green Revolution produced food for the earth’s growing population as it spread chemically and genetically enhanced forms of agriculture.
D. Medical innovations (such as the polio vaccine, antibiotics or the artificial heart) increased the ability of humans to survive.
E. New energy technologies (such as the use of oil or nuclear power) raised productivity and increased the production of material goods.
II. Humans fundamentally changed their relationship with the environment.
A. Humans exploited and competed over the earth’s finite resources more intensely than ever before in human history
B. Global warming was a major consequence of the release of greenhouse gases and other pollutants into the atmosphere.
Pollution threatened the world's supply of water and clean air. Deforestation and desertification were continued consequences of the human impact on the environment. Rates of extinction of other species accelerated sharply.
III. Disease, scientific innovations and conflict led to demographic shifts.
A. Diseases associated with poverty (such as malaria, tuberculosis or cholera) persisted, while other diseases (such as the 1919 influenza pandemic, ebola or HIV/AIDS) emerged as new epidemics and threats to human survival. In addition, changing lifestyles
