Migration into Urban Areas Taxes Social Infrastructure
By 2050, the UN says, there may be 3.5 billion slumdwellers, out of a total urban population of about six billion.
Land encroachments increase wildlife interactions
Demand for Protein

Rapidly expanding middle class driving The need for Protein
Emerging market economies - inrease % of the global middle class:
2000: 56%2030: 93% China and India alone will account for 2/3 of this expansion
Global Food Supply
• In 2008, 21 Billion Production Animals, a global population of 6.5 billion people
• 50% Increase in Animal Protein by 2020
A rapidly expanding middle class will lead to an increase in trade
Major global trade flows of dairy products, 2003

• Significant disruptions to food security through:– Reduced productivity» Destroying a families livelihood E.g. PPR spreading across
Africa» Negatively impacts sustainability e.g. BlueTongue– Disruption of food supply chains» E.g. FMD in South Africa, South Korea; hpAI– Foodborne illnesses» Real or perceived eg E.coli O157 and pH1N1 respectively
