EduNinja• Describe a sustainable resource as one which is produced as rapidly as it is removed from the environment so that it does not run out
The Canadian Government were concerned about overfishing at the Grand Banks in the Atlantic Ocean.
As a result, commercial fish stocks were monitored from 2002 until 2013.
The population data for four species of fish are shown in Fig. 4.1.

Sustainable development is required to manage fish stocks.
Define the term sustainable development.
A researcher investigated the population growth of fish for fish farming. The researcher stocked a farmer's lake with a small number of these fish and recorded the number of fish over the next five years. The researcher's results showed that the population of fish had increased exponentially.
Like fish stocks, forests can be a sustainable resource.
Discuss what is meant by the term sustainable resource, using forests as an example.
What can be managed sustainably?
taking coal from a coalfield
taking gas from under the earth's surface
taking oil from an oilfield
taking wood from a woodland

Which definition of sustainable development is correct?
