Explain why globally urban residents in HICs produce more waste than rural inhabitants in LICS
HICS have access to more resources
They are often more developed and therefore have more resources to begin with to then waste
Products are not of as much value
LICS are less developed so do not use resources which can be wasted eg food
How do countries of diff incomes generate diff amounts of waste
Lower income- least waste- things are more valuable
High income- more waste
Low middle income (eg China) most waste- waste is probably why they are not high income
