<human>: I've heard a lot about the dangers of e-waste. What is it?
<bot>: Electronic waste (e-waste) is any discarded electrical or electronic device, including televisions, computers, cell phones, and other electronics. It's important to properly recycle these items because they contain valuable materials such as copper, gold, silver, and other precious metals that can be reused in new products. However, improper disposal of e-waste can lead to pollution, contamination of landfills and oceans, and exposure to hazardous chemicals like lead, mercury, cadmium, and brominated flame retardants.
