What is a Natural Resource? NON-RENEWABLE: any form of matter or energy not able to be formed within a human lifetime RENEWABLE: any form of matter or energy that regenerates within a human lifetime or is consistently available. Natural resources are materials and components (something that can be used) that can be found within the environment

Man-made products are composed of natural resources Can you figure out what your products are made of? MaterialsNatural Resource RenewableNonrenewableDisposal Poll Experiment?

Life Cycles Conventionally, your item follows a linear life cycle pathway How can you turn this cycle into a circle? – Consider extraction…disposal… Share with your tablemates; be prepared to share one example to the class.

Zero Waste…is it possible? sults_video&playnext=1&list=PLB1CE7BCBBED3DA4B sults_video&playnext=1&list=PLB1CE7BCBBED3DA4B

CAN YOU PLAN A ZERO WASTE PARTY?? You have 10 minutes now; 10 minutes tomorrow to get started….

How long can you last? 1.You need to get one fish each year in order to live. 2.Any extra fish you collect, you can sell for profit. 3.Any fish remaining in the lake will reproduce (at replacement level).

What did you do to regulate the number of “fish” you caught in the second game? Private ownership Private ownership Users pay approach Users pay approach Regulated access Regulated access – Use resources at rates below sustainable yield

Think about it… What are some natural resources that are global common resources? So how would you define… – Tragedy of the commons – Sustainable use The maximum rate at which people can use a resource without reducing the ability of the resource to renew itself is called sustainable yield.

Resources & Reserves

Resources ≠ Reserves Resources – amounts of material that are known/ assumed to exist that can be extracted NOW or in the FUTURE for a POSSIBLE profit $ Reserves – known amounts of material that can PRESENTLY be extracted for a PROFIT – “proven” Do Worksheet Problem #1, #2, #3

The lifetime of a resource depends on… 1.How much we have 2.How fast we use it

What reserves does the US have? Fossil fuels = – Oil – Coal – Natural Gas Why are we depleting our reserves (running out)? –

Changing estimates Why do reserves of resources usually last much longer than most early estimates predict? How does technology, economics, and politics influence the estimates of reserves and resources? YearProven Reserves (billion barrels)

Resource Depletion static, exponential, real world
