The essence of a good society is that every member, regardless of gender, race or ethnic origin should have access to a rewarding life. (JK Galbraith). This includes access to a sufficiency of clean and nutritious food. Harmful factors in the social , population and environmental influences are those which deprive populations of food through insufficient production or importation. Such situations arise from overpopulation relative to food supply from whatever cause, poverty, corruption, disease, bureaucratic sloth and war. The social and political consequences of famine continue for generations.
Malnutrition and poor water and sanitation contribute to 23% of the risk factors to the global disease pattern. The frequency of natural disasters has been increasing during the 20th Century. These lead to a breakdown in social services and failure to distribute food and hence poor nutrition
The reliable provision of food requires an organised society, determined mainly economic and social, and freedom from disease is largely economic and social”.
The influences on nutrition include:
- food availability and intake
- sufficient but not excessive suitable nutrients and chemicals which will vary with age, gender, growth and health of the population.
- the provision and availability of a sufficiency of clean water
- a nutrient intake which meets the requirements and constraints set by the individual’s genetic constitution
- a ready disposal of breakdown products of metabolism , urine and faeces
Food that is tasty and meets with the cultural, social and religious requirements of the population.
The world population will increase by between 2.5 and 3.5 billion by the year 2025. There are even projections that the world population will be greater than 8 billion in the year 2025, that is, it will have grown four-fold in a century. The world’s population has risen by 40% during the last 20 years, food production has risen by 50%, though Africa is an exception to this. Food production will have to rise by 75% over the next 30 years to feed 9 billion people.
Much of our modern thinking on population comes from the essay by Thomas Malthus ( 1766-1834) an Englishman who pioneered economic theory. He held that the power of populations to increase is infinitely greater than the power in the earth to produce subsistence for man. Population when unchecked , increases in a geometric progression.. The global average lifespan has increased from 48 to 66 years and will reach 73 in 2025.
