• Nutrient dense- a measurement of the nutrients
  provided in a food compared to the calories it
  contains.

  by-products, companionship, entertainment, etc.

What does the future hold?

• We are going through a livestock revolution.
• - Livestock needs will double by 2050.
• As well as a green revolution.
