Explain two ways in which computer and computerized equipment may cause environmental hazards.

Answer:

- Electromagnetic emissions. These are stray electrical and electromagnetic radiations emitted by electrical and electronic components inside the computer. Excessive exposure to such emissions may lead to health problems.
- Environmental pollution. Laptop batteries contain toxic calcium which may leak into the underground water tables and catchment areas if improperly disposed of. Poor disposal of computer hardware and other
computer accessories can also cause environmental pollution.
