Some examples of negative production externalities might include:

• The production of goods using environmentally damaging processes, such as factory farming or oil drilling
• The production of goods that generate hazardous waste or pollution, such as certain types of chemicals or toxic materials
• The production of goods that contribute to noise pollution or other forms of environmental disturbance, such as construction or transportation
• The production of goods that require the use of resources that could be used for other purposes, such as water or land

Negative production externalities can have serious consequences, and can often be addressed through policy measures such as taxes, subsidies, or regulations. These measures can help to internalize the negative externalities and encourage more sustainable and responsible production.
