Are CFL Bulbs really good for the environment? (Read Details)?
CFL bulbs reduce energy consumption, but harm the environment in ways that incandescent bulbs do not. CFL bulbs do contain a few milligrams of mercury. However, techniques such as using a metal-mercury amalgam to bind the mercury help improve the safety of the CFL bulbs. Also, during the life of the bulbs, the mercury tends to diffuse into the phosphor coating and the gl envelope. So, the mercury doesn't merely blow away, but ends up in landfills. The phosphor coating is another environmentally unfriendly aspect of CFL bulbs not shared with incandescents. Moreover, CFL bulbs produce electromagnetic pollution that incandescents do not. Since I've had a new CFL bulb break in my kitchen (of all places) due to poor packaging, and I spent a half hour cleaning up that hazmat incident, the cost of dealing with the toxicity hazards of CFL bulbs outweighs my energy savings. I still use a few CFL bulbs in fixtures where breakage is extremely unlikely, but I continue to use incandescents elsewhere. With regard for charges for recycling, I did a web search and found someone charging $120 for a five-gallon bucket that is to be filled with 30 used CFL bulbs and returned for recycling. I sure hope their customers feel all warm and fuzzy about recycling those bulbs, because, at those prices, the customers are certainly not realizing any economic savings from using CFL bulbs.
Bill Ayers and the weather underground?
Bill Ayers is a hypocrite for many reasons. One that he is a married guy when he was supposedly against that convention. He is also a hypocrite because he used bombs against his own country. He bombed buildings and endangered lives. He used the freedom granted to him by being an American against America. I think that makes him a hypocrite and a traitorous pig. He should kiss the ground of a country where you can blow up public buildings and now sit on the PTA.
Could my brother be opening up some?
I heard my brother and father talking about ( California Proposition 8 - is titled Eliminates Right of Same- Couples to Marry) this morning my dad and brother was talking about prop 8 and my brother said that he's voting NO on it. I was really shocked because all of this time he disliked gays and yes even myself. The last 2 months he's also been coming around me & my boyfriend more and seems more open-minded etc. Could he finally be getting past his hateful ways about gays?
