What does the term 'buffer' refer to in an environmental context?

In an environmental context, the term 'buffer' refers to a protective barrier against external impacts. Buffers are crucial in ecosystems, particularly near bodies of water, as they help mitigate the effects of pollution, erosion, and runoff. They can consist of vegetation or constructed elements that absorb or filter pollutants, stabilize shorelines, and provide a habitat for wildlife. By acting as a barrier, buffers play a vital role in maintaining water quality and protecting aquatic environments from harmful external influences.

The concept of buffers emphasizes the importance of maintaining healthy ecosystems through protective measures, particularly in areas where human activity may threaten ecological balance. This is why understanding the function of buffers is essential for environmental science and conservation efforts.
