1.1 Resources - Are We Running Out? Flashcards
What are resources?
UNESCO - “Materials that occur in nature and are essential or useful to
humans, such as water, air, land, forests, fish and wildlife, topsoil and
minerals.”
EPA – “Land, fish, wildlife, biota, air, water, groundwater, drinking water supplies, and other such resources (including the resources of the
exclusive economic zone), belonging to, managed by, held in trust by,
appertaining to, or otherwise controlled by, the USA, any state or local
government or Indian tribe, or any foreign government.”
Why are resources not stable over space and time
Resources can change with human needs.
things that weren’t resources can become resources and vice versa; ex of wild rubber
Explain how wild rubber was a resource, then wasn’t one anymore to finally become one again.
- Wild rubber was originally used by Amerindians to make rubber balls and foot protection
- In the 18th century, it was used for rain coats, but those rain coats were brittle in the winter and sticky/smelly in the summer
- No demand for it, no longer a resource
- 1839: vulcanization of rubber (heated with sulfur; makes it flexible and elastic material) → demand and innovation increases
- 1887: rubber tires for bikes
- The price of rubber sky-rockets bc of increasing demand, massive wealth in Amazon
- 1905-1920: Henry Wickman brings rubber seeds to England and starts plantations in Malaya, for a lot less money
- WW2: Japan captures the Asian (British) plantations and wild rubber rebounds.
- After the war, plantations are revived, the cost less, wild rubber collapses.
- 1930: synthetic rubber, plantation rubber declines
- Today: 60% of rubber is synthetic, wild rubber isn’t considered a resource.
What is the scarcity-development cycle?
→ New resources are created → Prices fall and Demand rises → Easily accessible reserves are exhausted → Scarcity of the resource → Prices rise and R&D is stimulated → Innovation leads to substitution, reuse, recycling → New resources are created → ...
What are non-renewable resources?
- There is a fixed amount of stock of the resource.
- The resource is depletable.
- OR natural replenishment is too slow aka over geological time
- The availability of non-renewable resources are measured in reserves
What are “in place” resources (in terms of non renewable resources) ?
In place resources are the resources that are technically recoverable and economically recoverable.
What are proven reserves?
Proven reserves are the known resources profitably extractible with reasonable certainty (90%) given current prices, technology and political conditions.
What are potential reserves?
Potential reserves are the profitably extractible resources at a given price.
(don’t care if not technically feasile)
If the price of a resource increases, does its proven and potential reserves increase or decrease?
They both increase with price.
What is a renewable resource?
- Renewable resources are resources which have a natural replenishment at a non-negligible and useful rate.
- They are public or common property
- Their availability is based on their regeneration rate.
- examples: grow or flow: forests, fish, water, wind, solar
What is sustained yield?
Sustained yield is the rate at which you can extract a resource continually without the ability to do so being compromised.
What are recyclable resources?
Recyclable resources are resources that exist in a form that allow them to recover once their original purpose has been fulfilled. (ex metals)
What is the Malthusian View? (on population and resources)
Increase of world population and resource scarcity are very serious problems.
What is carrying capacity?
- Carrying capacity is the maximum population that an environment can sustain without the population collapsing.
- Carrying capacity is related to a given species in a given environment, it differs between species and environments
What is the Marx (and neo-Marxist) view? (on population and resources)
- Population growth and resource scarcity is not a serious problem; it distracts us from the real problem which is the maldistribution of resources.
- They are not a problem because technology and trade can modify the carrying capacity upward.
