Industries use the Earth’s natural resources to manufacture useful products. In order to operate sustainably, chemists seek to minimise the use of limited resources, use of energy, waste and environmental impact in the manufacture of these products. Chemists also aim to develop ways of disposing of products at the end of their useful life in ways that ensure that materials and stored energy are utilised. Pollution, disposal of waste products and changing land use has a significant effect on the environment, and environmental chemists study how human activity has affected the Earth’s natural cycles, and how damaging effects can be minimised.
You should be able to:
Give examples of a finite and a renewable resource and how humans use them.
Describe and classify a resource as finite or renewable when information is given.
Explain the use of natural, sustainable, and finite resources.
Interpret information from different formats including graphs, charts, tables and text.
