Biotechnology Chapter 1 The Phenomena of Biotechnology Mr. Schanbacher

Essential Questions What is biotechnology? How does biological technology differ from technology derived from physical science? What is a genetically manipulated (modified) organism? Why is biotechnology important in feeding the world’s population? How is biotechnology used?

Technology List what you think of when you hear the word TECHNOLOGY: Why is biological technology so “new”?

What is biotechnology? The manipulation of living organisms or parts of organisms to make products useful to humans. Using knowledge of cells to modify their activities in order to make living organisms more effective in serving people. What are some reasons that the development of biotechnology has been difficult?

Why is biotechnology important in feeding the world’s population? World Population A Hungry World… http://www.worldwatch.org/node/554

Green Revolution Began in Mexico in 1940’s Credited to Dr. Norman Borlaug Selective breeding for wheat with increased yields Research into fertilizers Also included rice (another leading food staple) Improved Irrigation Made it so many developing countries went from having food shortages to food surplus Problems: Rely on fertilizers and irrigation Plant improvements based on selection have leveled off Not accepted in all places (Africa) OVERPOPULATION!!!
