The Disposable Society
- A world where we dispose everything- 60000 kg of solid waste each day in NA-
throwaway society
- excess packaging = excess garbage = fast food is big offender
- pens self-destruct, disposable cameras, lightbulbs have mercury which is highly toxic
Thorstein Veblin- American sociologist came up with term: planned obscolescence
(disposability) – make a certain product, it will self destruct in a while
-people in the developed world consume 50 times more steel than the people in the third
-we live in a cleaner environment (developed world)
-80% of our solid wastes is not burned or recycled= natural decay= landfill site (running
out of them/nobody wants a landfill site)
- landfills can pollute water
-pay tax on disposing old tire
-guelph- garbage man collects organic/wet waste and they make fertilizer
- need water for everything= hydrological cycle
- Hydrological cycle: the earth naturally recycles water; 97% of all water in the world is
in the oceans; the sun hits it it evaporates; forms clouds; water evaporates at a lower temp
than most pollutants; water vapour that rises is pure; rain water is relatively pure;
pollutants if there are any get left behind rainwater falls on to land masses, streams
rivers then back to ocean- recycling process (nature recycles)
- water supply: Mesopotamia, china, Egypt, Rome, had water rights, were specified in
-middle east use a lot of ground water- rising population – water levels could become
critical – water is required for irrigation
-Saudi Arabia has huge desalinization technology- takes salt (ocean salt) from ocean
water- most water supplied is from this technology
- population growth puts a strain on water resources, globe consumes 4x the water it
consumed in 1950
