What doesn't belong to the environment?

In the context of the natural environment, there are various entities or elements that can be considered as not belonging to it. Here are a few examples:

Synthetic Materials: Certain man-made materials, such as plastics, synthetic fibers, and artificial chemicals, do not naturally occur in the environment and are created through human intervention.

Artificial Structures: Buildings, roads, bridges, and other constructed structures are not naturally occurring components of the environment.

Waste and Pollution: Waste products generated by human activities, such as garbage, industrial pollutants, and toxic chemicals, are not part of the natural environment and can have harmful effects on ecosystems.

Non-Native Species: Species that have been introduced to an environment where they did not naturally occur are considered non-native or invasive species. These can disrupt the balance of ecosystems and have negative impacts on native species.

Human-made Noise: Sounds produced by human activities, such as vehicle traffic, construction, or industrial operations, are not natural sounds in the environment and can disturb wildlife and disrupt ecological processes.
