Mercury is a highly toxic substance and everyday we're taking enough of that into our body, I certainly don't need more of that. Did a quick search in the internet and found that there are collection centres in the US for it, but I don't think we have one here yet. Recycling is a good thing, whatever it may be. If we ourselves do our bit part, the environment will be much better for future generations. Here is and interesting link to energy saving bulbs.
