I chose to discuss this article because it mentions why mercury is in Fluorescent lighting and why it is important to know what lights contain this element. 

"Mercury is the most essential ingredient for most energy efficient lamps." It is in fluorescent lamps, HID lamps, and others. This article lets you know that for these lamps to be efficient and have a long life, they have to contain mercury. This means we have to make sure that the proper disposal of these lamps is taken place. Although this is a huge issue, because not all people know this and they just send more mercury to the landfill, manufacturers are constantly trying to reduce the amount of mercury in the bulb. "The average four-foot lamp today contains over 75% less mercury than the same lamp would have contained in 1985.
