  1. Biotechnology What do all the following pictures have in common?

  2. What is biotechnology • Biotechnology involves the use of living systems, organisms, or parts of organisms to manipulate natural processes in order to develop products, systems, or environments to benefit people. • These may be products, such as foods, pharmaceuticals, or compost; systems, such as waste management or water purification; or environments, such as hydroponics. Biotechnology also includes genetic or biomedical engineering.

  3. Biotechnology in NZ Making milk proteins Milk products Finding contamination in food Beers Dairy industry Beverages industry Biotechnology in NZ Food Making enzymes Wines Waste management Processing farm effluent Getting rid of waste chemicals Composting

  4. Some information about biotechnology • Biotechnology involves the use of living thingsto make materials such as food, chemicals and medicines. • There are 4 main industries in NZ which uses Biotechnology • One of these groups is the food industry which produces enzymesand finds contaminationin foods. • The beverages industry produces beersand wines. • The dairy industry makes milk productsand milkprotein. • Finally the waste management industry involves getting rid of waste chemicals, processing farm effluentand compostingthe waste vegetation.

  5. Genetic modification • The fastest growing area of biotechnology in the world today is the genetic modification(GM) programs that have had billions of dollars pumped into them over the last few years. Some of this research has been useful. Some of the research has been controversial.

  6. Advantages of GM • Mass production of hormones such as insulin & human growth hormone, antibodies and vaccines. • Create animal & plant resistance to diseases and cancers. • Gene therapy replacing defective genes with functional ones. • Produce better tasting crops with better nutritional value & higher yield. • ‘Tailor making’ animals & plants to show desired characteristics.

  7. Controversy of GM • Could harm the environment if rogue organisms were formed. • Reduction of genetic diversity by producing cloned organisms with genetic defects. • Contaminating crops with GM crops. • Harmful pathogens could enter the gene pool. • Moral & ethical issues ‘messing with nature’
