Impact of Humans on Biosphere II

Over-Consumption


Who in the world

Who in the world?

  • See cartoon!


10 of world s population

10% of World’s Population

  • Consumes 90% of World’s resources

    • Including energy consumption  GHG

    • Including raw materials  wastes, dumps

    • Including 90% chemical wastes


World consumption classes

World Consumption Classes

  • Where do we (U.S. society) live?

  • Which is healthiest?


World consumption classes1

World Consumption Classes

  • Why do we stay where we are???????


World consumption classes2

World Consumption Classes

  • What if we want to change?

  • Should we recycle?


Old rs

Old “Rs”

  • Reduce

  • Reuse

  • Recycle (last, has role, but consumes fossil fuels, pollutes)


Four r s of sustainability

Four R’s of Sustainability

  • RETHINK!

  • Reduce

  • Reuse

  • Recycle


Rethink

RETHINK

  • Lifestyle

  • Not doable in a “top ten list”

  • Requires change in values, commitment, resolving old problems

  • Examples:


Rethink a few starter questions

“Rethink”: A few starter questions?

  • Why do we choose disposable plastic (toxic!) when we DINE IN KU?

  • Why do we drive when walking or biking would only take 10 – 15 minutes?..... And then pay to use an exercise facility?

  • Why do we use lawn-mowers that hurt our grass, our atmosphere and our wallet?


Rethink a few starter questions1

“Rethink”: A few starter questions?

  • Why do we manufacture containers (manufacturing pollutes) and sell essentials (water, milk for infants) that we can get for free?

  • Why do we use light-bulbs which hurt our atomosphere and wallets?


Reduce

REDUCE

  • Buy only what you need!(less consumption of resources, etc)

  • Virtually 100% of what you buy eventually end up in a landfill But also, what if all Americans reduced:

  • Their personal GHG emissions?

  • Their consumption of red meat, beef

  • The amount of electricity/gas they used?

  • The amount of raw material they consumed?

  • The amount of disposables they used?

  • Reduction is underappreciated! Ecological actions do not have to be “All or nothing!”


Reuse

REUSE

  • Economical $$$$$$$$$ !!!!!!!!!!!!!!!!

  • Buy for durability!

  • (less consumption of resources, pollution, etc)

  • Examples:Use washable dishes in KU!, Ask parents for cloth napkins,


Recycle

RECYCLE

  • Recycling Aluminum yields best results(Mining & extracting pure Al is VERY energy/fossil fuel intensive; recycling takes minimal energy)


Finally

Finally….

  • You know the history of the world

  • You are now helping to write the future….

  • Good luck on finals!Gave a great life!
