What is the effect of cfcs life on earth?

Compact fluorescent bulbs are a more efficient way to provide electrical light within homes and other buildings.  These bulbs are one of the easiest ways to save money.  According to GE, compact flourescent bulbs, or CFLs for short, use 70% less energy than a traditional, incandescent bulb and last up to 10 times longer than a standard incandescent bulb.  As society pushes for improved efficiency, compact flourescent bulbs need to be carefully examined.  Although these bulbs are more efficient, there are many problems with compact fluorescent bulbs.

i think i can answer even without the example. over time with environmental changes, sometimes a group of animals will adapt to better survive. take a moth for example. if the trees the moths use to camouflage themselves from predators, started to die or change colors themselves, the moths may, overtime of course, change color too. its just adapting to its surroundings. hope i was of any : )
