Anyhow, saving man is doomed to fail. The more you save (eg. by feeding unsustainably large families in Africa), the more the population grows to unsustainable levels. The world population has grown by 2.5 times in the last 70 years. A big problem for future generations of man, not a problem for the planet.
So, no more about saving the planet. Be honest, you are saving your own skin, and your next concern is for your family. The planet will be just fine.
W66, my question was to ask, in general, if by being efficient in our energy usage, our small country would make a difference with regard to the big picture, i.e. when countries such as China are utilising most fuel sources, eating up every ounce of scrap metal, to produce somewhere more affluent for its new rich? Why shouldn't we be able to leave our lights on, heat our homes up to tropical level, drive large and totally unnecessary vehicles, fly everywhere, etc.? What difference will we make other than to feel smug and self righteous when we, as a planet full of people, will all end up in the same situation however it may turn out?
I will add though, that I do try to switch off lights which aren't needed, walk to the shop on occasion and turn the room stat down a few degrees, but mainly because it's a needless cost to do otherwise, not to preserve any energy for someone else to use.
Also, with regard to the over population of our tiny sphere, when it all goes T.U. then survival of the fittest will sort things out!
