Explain how products that pose a hazard to the environment can be manufactured and disposed of safely.

Answer:
The correct answer will include that manufacturers can use purification to remove dangerous objects during the manufacturing phase. If the material is removed, it must be disposed of properly. Electronic devices and batteries that store acids can cause severe damage to humans and the environment; mercury in thermometers is also toxic. These products can be properly recycled so the materials do not enter the waste stream and cause health hazards.
