Question

Quizplus · Accepted Answer

Millions of mobile phones are disposed of every year, but the recycling practices are very poor. Many of the materials used in mobile phone production, such as precious metals and hazardous chemicals, can cause environmental damage if not properly disposed of or recycled. This makes mobile handsets a threat to the environment. Choices A and B are not entirely accurate as mobile handsets consume relatively low electric power and emit radio waves, not infrared radiation. Choice C may contribute to the issue but is not the main reason why mobile handsets are a threat to the environment.
