ANSWERS1. List the five parts of the linear model of consumption and explain each in one sentence.

Extraction is mining, harvesting, and striping the earth of its natural resources.

Production is using energy and chemicals to turn the natural resources into products.

Distribution is delivering the products to stores.

Consumption is buying those products maybe because advertisements have convinced us that we need them, and they are likely to break quickly or otherwise become obsolete.

Disposal is getting rid of the old products, typically very soon after purchasing them.

3 pts each

2. We talked about how each part of the model hurts the environment in some way. Give an example for each.

Extraction: mining and harvesting hurts ecosystems and habitats

Production: chemicals used are toxic and by-products are polluting

Distribution: shipping, trucking products all over the globe pollutes the air

Consumption: buying lots of stuff means lots of packaging that gets trashed

Disposal: filling up landfills and/or incineration causes toxins to get into our water and air

2 pts each

3. What is a finite resource?

A resource that cannot be renewed; opposite of infinite

A resource that will be used up.

3 pts

4. What is planned obsolescence? Give an example.

Planned obsolescence is when an item is manufactured to break so that the consumer has to replace it.

An example is a blender with plastic gears.

4 pts—2 for definition, 2 for example

5. What are two things you can do as a consumer to help?

2 pts each
