Study Notes
Population Growth
- World population is expected to rise from 6.05 billion to 7.5 billion
- Philippines population is expected to rise from 82 million to 122 million
Food Production
- World cereal production should increase by 50%
- Philippine rice production needs to increase by 40% from 12 million tons to 18 million tons
Agricultural Resources
- Agricultural resources are limited due to deforestation, overgrazing, and land conversion
Biotechnology
- Biotechnology is a technique that uses living organisms to develop new products and improve existing ones
- It can be used to improve plants, animals, and microorganisms for specific applications
Examples of Biotechnology
-
Plant biotechnology:
- Genetically engineered (GE) plants for pest resistance, disease resistance, and increased yield
- Plant protoplast fusion
- Plant tissue culture
- Biofertilizers
-
Animal biotechnology:
- GE animals for disease resistance and increased milk production
- Animal vaccines
- Embryo transfer
-
Microorganism biotechnology:
- GE microorganisms for biocontrol agents against pests and diseases
- Recombinant DNA for disease diagnostics
- Monoclonal antibody production
- Fermentation
Benefits of Biotechnology
-
Human health:
- Insulin for diabetes
- Interferon for cancer treatment
- Hepatitis B vaccine
-
Environmental protection:
- Bioremediation: using living organisms to clean the environment
-
Food production:
- Improved food quality and processing
- Better-tasting and more nutritious foods
- Cleaner food
Genetic Engineering
- Technique that transfers genes of interest to develop and improve organisms
- Allows for the direct transfer of genes between organisms, even those distantly related
- Compared to conventional breeding, genetic engineering offers a faster way to achieve desired results
Genetically Modified Organisms (GMOs)
- Products developed through genetic engineering
- 2001 and 2002 global area of GMO cultivation (in millions of hectares):
- USA: 35.7 million (68%) and 39 million (66%)
- Argentina: 11.8 million (22%) and 13.5 million (23%)
- Canada: 3.2 million (6%) and 3.5 million (6%)
- China: 1.5 million (3%) and 2.1 million (4%)
- South Africa: 0.2 million
