Final answer:
Discarded tires should not be stockpiled due to environmental hazards, mosquito breeding grounds, and the waste of resources.
Step-by-step explanation:
Discarded tires should not be stockpiled due to several reasons:
Environmental hazards: Stockpiling tires can lead to environmental hazards such as the risk of fire and the release of hazardous pollutants into the air, soil, and water. When tires catch fire, they release toxic chemicals and gases, including carcinogens, which can be harmful to human health and the environment.
Breeding grounds for mosquitoes: Stockpiled tires can serve as breeding grounds for mosquitoes, which can increase the risk of vector-borne diseases such as dengue fever and West Nile virus.
Waste of resources: Tires contain valuable materials that can be recycled and reused. By stockpiling tires, we miss the opportunity to recover these resources and reduce the demand for raw materials.
