What can I do for the Environment?

Using less power, eating less meat, avoid flying, reduce water consumption: If I keep this in mind, am I then on the way to become a good world citizen?

Well, using electricity only when needed, for instance turning off lights in rooms that are not being used, turning off cooling or heating in rooms that are not being used, surviving in room temperature of 28C when the outside temperature is more than 33C, try to use as little water as possible when it has not rained sufficently, using the car only when absolutely necessary. Some of this is not always easily achieved but I try to keep it more and more in mind. The only thing I have no difficulty with is, that is eating very little meat. I have never liked to eat a lot of meat!

Another issue is flying. Since 1977 I have been flying overseas more than half a dozentimes. I tell myself,  I should in future not fly anymore at all. But can I really stick to it? If Australia would be in the midst of WW3 right now, I am sure I would not be able to fly anywhere.  At the moment we behave in Australia as though we are far away from having actual war conditions. We should really restrict ourselves as though absolute war conditions did apply. Itseems to me most people do not think this way, not yet anyway. Most people seem to want to ignore that there is a worrying increase in climate change, at least they want to ignore this in their personal lives.
