People Using <strong>Resources</strong><br />
<br />
<br />
What resources are<br />
the people <strong>on</strong> the<br />
beach sharing?<br />
Are the resources<br />
here adequate to<br />
comfortably<br />
support the<br />
populati<strong>on</strong> of<br />
people <strong>on</strong> this<br />
beach?
Populati<strong>on</strong>s and the Use of Natural<br />
<br />
<strong>Resources</strong><br />
All organisms use resources to maintain<br />
their existence. The use of these resources<br />
has an impact <strong>on</strong> the envir<strong>on</strong>ment.
Populati<strong>on</strong>s and the Use of Natural<br />
<br />
As populati<strong>on</strong>s<br />
increase in size<br />
the demand for<br />
resources also<br />
increases.<br />
<strong>Resources</strong>
Populati<strong>on</strong>s and the Use of Natural<br />
<br />
Because<br />
resources are<br />
limited,<br />
populati<strong>on</strong>s<br />
eventually will<br />
reach the<br />
carrying capacity<br />
of the<br />
envir<strong>on</strong>ment and<br />
stop growing.<br />

What can you infer<br />
from this photo about<br />
the amount of<br />
garbage a city<br />
produces and the<br />
amount of space<br />
needed to dispose of<br />
it?<br />
What problems might<br />
occur if the city<br />
c<strong>on</strong>tinues to produce<br />
the same amount of<br />
garbage?

<br />
<br />
Modern societies require large<br />
amounts of land resources. The<br />
extracti<strong>on</strong> of land resources can<br />
disrupt <strong>Earth</strong>’s <strong>Earth</strong> s surface.<br />
Growing populati<strong>on</strong>s increase the<br />
demand for food. Food producti<strong>on</strong><br />
can cause habitat loss, erosi<strong>on</strong> and<br />
water polluti<strong>on</strong>.

<br />
<br />
Urban development causes habitat<br />
loss, increased erosi<strong>on</strong> and polluti<strong>on</strong><br />
of nearby areas.<br />
The impact of using land resources<br />
can be minimized through the use of<br />
modern techniques such as<br />
reclamati<strong>on</strong> and bioremediati<strong>on</strong>.
