Electronic waste or e-waste refers to discarded electrical or electronic devices like cathode ray tubes, chips, plastics from electronics, and printed circuit boards. E-waste is dangerous as it contains carcinogens and toxic chemicals that can cause health effects like cancer, liver damage, and developmental issues. Proper e-waste management includes planning collection, recycling, and disposal to reduce environmental contamination while encouraging the 3R's of reduce, reuse, and recycle. All governments, industries, and consumers should cooperate to sustainably manage e-waste.
