Impact on the Environment:
Positive Effects:
Improved public health
Increased global mobility

Negative Effects:
Vaccine waste
Resource allocation

Effects on Plants/Animals:
Minimal direct impact on plants and animals. However, the increased human health could indirectly benefit ecosystems by reducing human suffering and fostering more stable communities that could better manage environmental resources.

Effects on Air, Water, and/or Land:
Air: No direct impact on air quality, though public health improvements could result in less respiratory illness, indirectly benefiting air quality in heavily industrialized areas.

Water: Vaccination campaigns often involved community mobilization, which included local water sources for people to gather and receive vaccines. However, there was no significant environmental damage from water use.

Land: Vaccine production and distribution involved logistical activities, but the environmental impact on land was minimal compared to the benefits of polio eradication.
