Questions: Which of the following is an example of an industrial practice that contributes to the tragedy of the commons? Burning fossil fuels for energy production (B) Creating constructed wetlands on abandoned land (C) Enacting and enforcing legislation on point-source pollutants (D) Promoting aluminum and glass recycling

The answer is Burning fossil fuels for energy production.

Burning fossil fuels for energy production is a classic example of the tragedy of the commons. This practice leads to air pollution and contributes to global warming, which are negative externalities affecting the entire planet. The tragedy of the commons occurs when individuals or companies use a shared resource (in this case, the atmosphere) in a way that depletes or degrades it, leading to long-term negative consequences for everyone.

Creating constructed wetlands on abandoned land is generally considered an environmentally beneficial practice. It helps in water purification, provides habitat for wildlife, and can even help in flood control. This does not contribute to the tragedy of the commons; rather, it is a positive environmental action.

Enacting and enforcing legislation on point-source pollutants is a regulatory approach to managing environmental impacts. This helps to mitigate the tragedy of the commons by controlling pollution and protecting shared resources. It is a solution rather than a contributing factor.

Promoting aluminum and glass recycling is an environmentally friendly practice that helps reduce waste and conserve natural resources. This practice does not contribute to the tragedy of the commons; instead, it helps alleviate it by reducing the demand for raw materials and minimizing environmental degradation.
