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.

Communication:
-new technology such as phone, computers, TV

Transportation:
-Trains, cars, planes, boats,
became faster, more reliable, and less reliant on humans

C. The Green Revolution produced food for the earth's growing population as it spread chemically and genetically enhanced forms of agriculture.

 
The 2011 DBQ asked students to "analyze the causes and consequences of the Green Revolution in the period from 1945 to the present"

D. Medical innovations increased the ability of humans to survive.


Dr. William Glenn invented the heart procedure in 1954 in an attempt to treat babies whose oxygen flow was cut off at the heart, a phenomenon known as "blue baby", due to the blue appearance from the lack of oxygen.He and Dr. Sewell went on to invent the artificial heart following World War II.

 

E. Energy technologies including the use of oil and nuclear power raised productivity and increased the production of material goods.

Science was often misunderstood and as a result, academic disciplines in this area became highly specialized and professionalized. This in turn created a new social class that excluded "outsiders" and amateurs in the field. 

 

  • Social Anthropology was one advance that caused humans to reconsider their relationships to each other.

 

  • Sociobiology had the same affect. It created the idea that evolutionary necessities determined the differences between societies. It was believed that genes limited freedom to equalize differences in society because some were naturally inferior to others. This was the basis for many institutions, including slavery.

 

II. As the global population expanded at an unprecedented rate, 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.

 

Humans became dependent on resources such as fossil fuels and coal.
Trees, water and land also exploited and not replenished fast enough.

 

B. Global warming was a major consequence of the release of greenhouse gases and other pollutants into the atmosphere.

 

With the increase in industry and transportation, the five major Climate change pollutants have drastically increased. (H2O,CO2,Methane, CFC, NOx)

C. Pollution threatened the world's supply of water and clean air. Deforestation and desertification were continuing 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.


Human understanding of disease drastically improved in the late 19th century, resulting in vaccinations for "modern plagues" such as typhoid and smallpox. This, along with improvements in hygiene and public sanitation increased the average human lifespan from 31 to 49 years. Along with an accompanying decline in death rates, this increase in life expectancy resulted in one of the highest population growth rates in human history.

A. Diseases associated with poverty persisted, while other diseases emerged as new epidemics and threats to human survival. In addition, changing lifestyles and increased longevity led to higher incidence of certain diseases.

B. More effective forms of birth control gave women greater control over fertility and transformed sexual practices.
