Environmental Economic Models
View natural resources as important but not indispensable.
Depleted natural resources can be replaced with substitutes.
Continuing economic growth is necessary for providing business with profits and workers with jobs.
Contend there are no substitutes for vital natural resources: air, water, soil, biodiversity.
No substitutes for ecological services: climate control, air and water purification, pest control and nutrient recycling.
Contend conventional economic growth is ultimately unsustainable: irreplaceable natural capital can be depleted and degraded.
Warn that many are getting rich in the short term by depleting and degrading natural capital that is necessary to sustain all life and economy in the long term.
Ecological Economist Model
1. Resources are limited.
Should not be wasted.
No substitutes for vital resources.
2. Encourage environmentally beneficial and sustainable economic development.
Discourage environmentally harmful and unsustainable economic growth.
3. Use of Full-Cost Pricing
Market pricing should account for the harmful environmental and health effects of producing goods and services.
