Bluetooth headset...necessary or not? Saving on water and electricity...

Lately, I am trying to save on energy which is why I look at the need for a bluetooth.
I was reading on the wave emitted by the Bluetooth radiation and no doubt, the Bluetooth signal at 1 milliwatt is extremely low, compared to some cell phones, which may emit up to 3 watts.
However, I believe that normal headset is sufficient for such usage. I mean most of the time we would be holding our mobile while on communication. Even when we were on the road, using a normal headset is sufficient and it saves on the energy used to charge battery.

For me, I decided not to use my Bluetooth headset anymore.

Just the other day, I was talking about fighting against global warming but most of us couldn't even be bothered about the most important element in our lives, water. Probably because it was cheap, none of us really consider the need to save on water usage. Some of us even left the water tap running while brushing out teeth, and there is not a concern to fix the leaking water at home. Especially now that I am staying inside the university campus, I've seen so much irresponsibility act such as leaving the water tap running and most students won't bother to save on electricity, just because they believe they pay their part.

Did you know that...
  • On average, a person uses about 200 litres of water per day, of which 5-10 litres is for basic survival, ie drinking and food preparation.
  • Approximately half the water supplied to urban areas in Australia ends up as waste water, according to a report by the Institute for Sustainable Futures prepared for the Water Services Association in 1998.
And we are only talking about Australia here.

Some of the ways to save on water:

  16. . Insulate your water pipes. You'll get hot water faster plus avoid wasting water while it heats up.
And we are only doing the very small part of it. Think about the difference you can make...make the difference today!
