How did the establishment of permanent human settlements affect pollution levels?
How did the establishment of permanent human settlements affect pollution levels?
- Pollution was not affected.
- Pollution remained the same as people developed sustainable practices.
- Pollution decreased because waste was more concentrated and easier to manage.

Study Notes
- Pollution is the addition of any substance (solid, liquid, or gas) or energy (heat, sound, radioactivity) to the environment faster than it can be dispersed, diluted, decomposed, recycled, or stored harmlessly.
- Major kinds of pollution are usually classified by environment.
- These include air pollution, water pollution, and land pollution.
- Modern society is also concerned about specific types of pollutants.
- These include noise pollution, light pollution, and plastic pollution.
- Pollution of all kinds can have negative effects on the environment and wildlife.
- Pollution can often impacts human health and well-being.
- Environmental pollution can be caused by natural events such as forest fires and active volcanoes.
- Pollution generally implies that the contaminants have an anthropogenic source, which means a source created by human activities.
- Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place.
- Ancient human settlements are frequently recognized by their wastes like shell mounds and rubble heaps.
- Pollution was not a serious problem as long as there was enough space available for each individual or group.
- With permanent settlements by great numbers of people, pollution became a problem.
- Cities of ancient times were often noxious places, fouled by human wastes and debris.
- Beginning about 1000 ce, the use of coal for fuel caused considerable air pollution.
