Meat production has grown 2.6 times faster than population since 1961
Production of meat in the world in 1961 was 71,357,168.89 million tonnes and in 2012 was 302,390,507.24 million tonnes. Calculation: (302,390,507.24 - 71,357,168.89)/71,357,168.89 x 100 = 324%
Population in 1961: 3,082,829,000 people; population in 2010: 6,916,185,000 people. Calculation: (6,916,185,000 - 3,082,829,000)/3,082,829,000 *100= 124 %
324% / 124% = 2.6
