MANAGEMENT

Detailed explanation-1: -Hazardous materials are safely disposed of Substances such as mercury and lead can be found in computers. If they end up in landfill, they can ultimately enter the soil or streams and rivers causing dangerous pollution to insect life, aquatic life, animals and ultimately ourselves.

Detailed explanation-2: -They can release heavy metals and other toxins that can eventually find their way into water supplies, rivers, and even the oceans. This includes plastics; almost all plastics used in electronics are not biodegradable, though they can be recycled.

Detailed explanation-3: -Why? First, your old electronics are chock full of toxic stuff that should never make it to a landfill, like arsenic, lead, and cadmium. If those materials make it into landfills, they can potentially leak into our ecosystem, damaging plant and animal life and potentially impacting our food supply.
