  growing faster than their food supply
• Less land available to farm
• 2 Billion hectares of arable land has been
  degraded
• Size of Canada and USA

10
Fresh Water

• Fresh water supply is finite
• Demand is increasing with higher populations and
  higher per capita usage
• Unclean water/poor sanitation kill 12 million ppl
  a year
• By 2025 the worlds population is projected to be
  8 billion..3 billion of which may face water
  shortages

11
Forests

• Nearly half of the worlds original forest cover
  has been lost

• Canada sends 420 ooo tons of food aid to
  countries in need

  aid world wide
