Rapid advances in science altered the understanding of the universe and the natural world and led to the development of new technologies. These changes enabled unprecedented population growth, which altered how humans interacted with the environment and threatened delicate ecological balances at local, regional, and global levels. However, new modes of communication and transportation virtually eliminated the problem of geographic distance. In regards to feeding the mass of billions of humans now on earth, it was The Green Revolution and commercial agriculture which increased productivity and sustained the earth's growing population as it spread chemically and genetically modified forms of agriculture.

Explain how the development of new technologies changed the world from 1900 to present
HISTORICAL DEVELOPMENTS
New modes of communication—including radio communication, cellular communication, and the internet—as well as transportation, including air travel and shipping containers, reduced the problem of geographic distance. Energy technologies, including the use of petroleum and nuclear power, raised productivity & increased the production of material goods. Also, more effective forms of birth control gave women greater control over fertility, transformed reproductive practices, and contributed to declining rates of fertility in much of the world. In addition, the Green Revolution & commercial agriculture increased productivity & sustained the earth’s growing population as it spread chemically & genetically modified forms of agriculture. Lastly, Medical innovations, including vaccines and antibiotics, increased the ability of humans to survive and live longer lives.
