AQA Science Exam Question and Answer
Question:
Explain the concept of "natural resources" and provide an example to illustrate how their availability can impact ecosystems and human societies.
Answer:
The concept of "natural resources" refers to the various materials and elements that are derived from the environment and are essential for the survival and development of both ecosystems and human societies.
For instance, let's consider a freshwater ecosystem that relies on a river as its primary water source. The river provides water for drinking, irrigation, and habitat for various species. However, due to increased human demand and pollution from nearby industries, the water quality of the river begins to deteriorate.
As a result, fish populations in the river decline due to pollution, leading to a disruption in the food chain. Additionally, communities downstream face challenges accessing clean and safe drinking water, impacting their health and well-being. In this scenario, the availability and quality of the natural resource (freshwater) directly influence the health of the ecosystem and the livelihoods of people dependent on it.
This example highlights how the management and conservation of natural resources are crucial to maintaining the balance of ecosystems and ensuring the sustainability of human societies. It also emphasises the interconnectedness of nature and human activities, underscoring the need for responsible resource use to prevent negative impacts on both environments and communities.
