CHAPTER 7: EARTH’S RESOURCES<br />

3<br />

4<br />

Ethical considerations for resource use<br />

Obtaining a resource may change, pollute or destroy native habitats<br />

or reduce the biodiversity of an area. Sometimes it is the use of the<br />

resource that can be damaging to the environment. The burning of<br />

fossil fuels results in the release of carbon dioxide into the atmosphere<br />

at levels well above what would naturally occur. Carbon dioxide traps<br />

heat in the atmosphere that would normally escape into space. This<br />

has caused average global temperatures to rise and is contributing to<br />

climate change. If we are to limit the amount of carbon dioxide being<br />

emitted, we need to use alternatives to fossil fuels to produce energy.<br />

What is an example of an ethical consideration?<br />

Ethics involves considering different opinions<br />

Before a resource is extracted and used, information and opinions are<br />

gathered about the resource and the local environment so that choices<br />

and decisions can be made.<br />

There are always groups of people with different opinions and this can<br />

make the final decision difficult to make. Coal is one of the resources<br />

that is frequently debated in Australia. Different groups will be affected<br />

in different ways depending on the choices that are made.<br />

using coal<br />

Scientists<br />

Impact and point of view<br />

Wants to extract as much coal as possible, spending<br />

as little as possible to maximise profits<br />

Wants to utilise a cheap fuel source (such as coal)<br />

to meet electricity demands<br />

Want the industry to continue to provide them<br />

with work<br />

Want the mining and burning of coal to stop so that<br />

carbon dioxide emissions are greatly reduced and<br />

ecosystems are protected<br />

Want governments to support renewable energy<br />

technologies so that renewable energy becomes the<br />

primary source of electricity as well as a source of<br />

employment<br />

May be concerned by damage to the local<br />

environment and that pollution could be harming<br />

their health<br />

Have undertaken many studies showing that the<br />

burning of fossil fuels such as coal is causing<br />

climate change<br />

Why can making decisions about using resources be difficult?<br />

CHECKPOINT 7.6<br />

1 Describe how obtaining and<br />

using a resource can be of<br />

benefit to society.<br />

2 Describe how the natural<br />

environment can be affected<br />

by obtaining or using resources.<br />

3 What gas is released into the<br />

atmosphere when a fossil<br />

fuel is burnt? Describe the<br />

environmental impact of<br />

this gas.<br />

4 Outline some ways that mining<br />

impacts on:<br />

a the environment<br />

b society and people<br />

c industry and the economy.<br />

5 Brainstorm some ways that<br />

mining companies could<br />

reduce their impact on the<br />

environment.<br />

6 Stopping coal mining in<br />

Australia would reduce a<br />

significant portion of income<br />

coming into the country’s<br />

economy, but would stop<br />

considerable environmental<br />

damage from the mining<br />

and use of the coal. Does<br />

the benefit of conserving the<br />

environment outweigh the cost<br />

to the economy? Use evidence<br />

to support your response.<br />

INQUIRY<br />

7 Research your local energy<br />

supplier. Find out where<br />

your energy is sourced from.<br />

What percentage is renewable<br />

and what percentage is<br />

non‐renewable? Discuss some<br />

ethical considerations (what is<br />

right and wrong) about how<br />

your power is generated.<br />

SUCCESS CRITERIA<br />

I can describe some ethical<br />

considerations of obtaining<br />

and using resources.<br />

I can describe some<br />

different points of view<br />

people may have on the use<br />

of non-renewable resources<br />

in Australia.<br />
