2. Biotechnology in Food Production

3. Biotechnology i) Bovine Growth Hormone
Can be injected into cows to have them increase mile production by 8-17%

4. Biotechnology
rBGH is banned in Canada, Japan, and Australia

5. Biotechnology Concerns Cancer risk: Colon, Prostate, Breast
Antibiotic Resistance
A tool for factory farms: in the US 22% of cows injected with rBGH

6. Biotechnology ii) Packaging to produce spoiling
Plastic wrap and other food packing can help prevent food from spoiling

7. Biotechnology
Natural antibiotic substances combine with biodegradable polymers to create food wraps that prevent biofilm formation
Some are even edible!
Hu00

8. Biotechnology iii) Golden Rice
Engineered in 2005, produced 23 times the B- carotene of original rice
Can be used to combat vitamin A deficiency

9. Environmental Factors and Food Supply

10. Environmental i) Pesticides
The industrial age introduced manufactured pesticides and fertilizers

11. Environmental Pros: Control Disease
Can lead to increased food production
Saves 8% of crops annually
Cons:
Can kill beneficial insects
Runoff chemicals can run into streams/lakes
1-5 million people affected by poisoning

12. Environmental
ii) Irradiation: Process of treating food with radiation, process slowly halts spoilage

13. Environmental
iii) Fertilizer: Added to soil to supply one o more nutrient (P,N, K)
Conservative estimations guess that 30-50% of crop yields are due to commercial fertilizer

14. GMOs
