Greatest population growth in less developed regions: 1950 32% of population lived in more developed regions of the world. 2000 20 % of population lived in more developed regions of the world. 2050 expected that 13% of the population will live in more developed regions of the world. The number of people the world can support is limited by: The average canadian produces 700 kg of household waste per year. Most waste is buried in well maintained sanitary landfill disposal sites. Buried contaminants can leak into soil and groundwater. Landfill sites are expensive to manage and require a lot of space, some waste is not biodegradable.
