Because the more energy consuming, traditional incandescent light bulbs are being phased out—at least for now—technologies like CFLs are being used more and more.
The problem is, while CFLs save tons of energy (and reduce tons of greenhouse gas emissions), their use and improper disposal is releasing tons of mercury into our air and water. And as you know, mercury is not something we want in our air, water or us.
