1 Factors Affecting Food Supply and Production
Food Supply Chain Factors Affecting Food Supply and Production Environmental and Biotechnology

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
