what are the global inequalities of food
- over 1 billion people do not get enough calories
- undernutrition affects a further 2 billion
- there can still be hunger in countries that produce a lot of food
what are the global inequalities of water
- variations in climate and rainfall affect supply
- capture, shortage and extraction can be expensive
- many poor countries have water shortages
- LICs use water for agriculture
- HICs use water fir industry
what are the global inequalities of energy
- richer countries consume more
- the middle east is a oil supplier, its own consumption is low. as NEEs become more industrialised the demand for energy will increase
in 2019 what percent of food that was eaten in the uk came from LICs
12%
why is the prices high in the uk for imported food
the food is produced cheaply in the LICs but high storage and transport costs result in high prices

where is consumption of energy the highest
North America and parts if the middle east
where is energy consumption the lowest
across most of Africa and parts of south east Asia
why is energy consumption increasing
- economic development
- population growth
- technology
where has energy resources been extracted from
increasingly challenging environments such as beneath the North Sea
