Question

What is one major environmental issue that CFL have on the environment?

This has to do with elements and the electromagnetic spectrum

Answer 1

CFLs (compact fluorescent lights) contain small amounts of mercury, a toxic heavy metal. If a CFL bulb breaks, the mercury can be released into the environment, where it can contaminate water and soil, and harm wildlife and human health. This is considered one of the major environmental issues associated with CFLs.
