However, disadvantages may include discomfort from prolonged wear and the potential for reduced mobility due to the added weight of the lamp. Additionally, if not properly maintained, the helmet's effectiveness can be compromised, posing safety risks.

The mining industry significantly contributed to the boom-bust cycle of Western towns by attracting large populations during mineral discoveries, leading to rapid economic growth and infrastructure development. However, once resources were depleted or mining operations became unprofitable, these towns often experienced dramatic declines, resulting in abandoned buildings and economic downturns. The volatility of mineral prices and the finite nature of mining resources exacerbated this cycle, leaving many communities reliant on a single industry vulnerable to collapse. Consequently, the mining boom fueled both prosperity and hardship in the West.

A pencil is not grown; it is primarily made from materials that are mined. The core of a pencil is typically made of graphite, which is a form of carbon that is extracted from the Earth through mining. The wood used for the pencil's casing usually comes from trees, which are grown and harvested. Thus, while some components are mined and others are grown, the pencil itself is manufactured, not directly grown.

The Democratic Republic of the Congo (DRC) is home to an estimated 1,000 to 1,500 small-scale and artisanal mines, along with several large industrial mining operations.
