10.1.1 Using the Earth’s Resources and Sustainable Development

Humans heavily rely on the Earth's resources to fulfil their fundamental needs, including warmth, shelter, food, and transportation. These resources can be categorised into two main types: natural resources and agricultural products. Natural resources, such as minerals, water, and air, along with agricultural practices, provide us with essential commodities like food, timber, clothing, and fuels.

In addition to the resources obtained directly from nature, finite resources sourced from the Earth, oceans, and atmosphere are processed to generate energy and materials that drive various industries. Chemistry plays a vital role in improving agricultural and industrial processes, leading to the creation of new and innovative products. Furthermore, chemistry contributes to sustainable development, which aims to meet the needs of the present generation without compromising the ability of future generations to meet their own needs.

To better understand the concept of using Earth's resources sustainably, it is important to recognise examples of natural products that are supplemented or replaced by agricultural and synthetic alternatives. For instance, traditional fabrics made from natural fibres like cotton can be supplemented or substituted with synthetic fibres such as polyester. Similarly, the use of renewable energy sources like wind and solar power helps reduce our reliance on finite resources such as fossil fuels.

In this contextA discrete unit of archaeological evidence, such as a layer of soil, a structure, or a feature, that can be recorded and interpreted., it is crucial to distinguish between finite and renewable resources. Finite resources have a limited supply and can eventually be exhausted. Examples of finite resources include coal, oil, and natural gas. On the other hand, renewable resources are naturally replenished over time, allowing for their sustainable use. Examples of renewable resources include sunlight, wind, and biomass.
