Who headed the Rockefeller project? What year did he win the Nobel Peace Prize?
Dr. Norman Borloug, 1950
What did Dr. borloug create?
High-yield varieties (HYV) - Dwarf plants - focused energy on seeds and not inedible parts (stems) - respond better to fertilizers - grew faster - more than one crop per year
What were the successes from the high-yield varieties?
World grain production increased
Rice and wheat prices dropped
Developing countries focused on social issues instead of food issues
Helped preserve rain forsests
What were some concerns of the Rockefeller projects?
Wealthy farmers benefited because they could afford special fertilizers
Loss of genetic diversity
Soil loss ability to grow food after multiple harvests
Small farmers lost their jobs
Developed countries benefited by selling pesticides
What is biotechnology with regards to food?
The application of biological processes to creat GMOs to increase food production
Explain the concerns of GMOs.
- super bugs (immune to pesticides)
- its new, so unknown long term side effects
- GMO seeds lose ability to product crops in the log term
- “terminator seed” gene could escape and devastate the gene population

What are the pros of of organic farming?
No pesticides, GMOs or herbicides are used
