One of the suggestions is that to make this work without too much hardship, we need to have a system of rationing, i.e. that each country should have a proportion of the earth’s resources equivalent to the people they have in the country and then if they do not use it they should be able to sell it to the countries that do use it. That sounds fair. He compares it to rationing during the war.
I tested my children on what they would be prepared to give up and found that actually they are quite reluctant to give up something they already have. So a tactic seems to stay with what you have at the moment and not replace it when it runs out. My oldest son pointed out that when you take something away it has a knock on effect on something else. Lets say we took the TV away, then he thinks he would be spending more time on the computer. If you take the computer away, he would spend more time watching TV. There is an element of non creativity about that. My suggestions fell on deaf ears...but the it is nearly the holiday season. I will have more time to think this one through.
I am trying to give up the car but it is proving very taxing at the moment. We will continue to look at options and see what we can do about them without having too much hardship. We live in the depth of the countryside 3 miles from the nearest town and although walking there is an option, it takes a lot of energy and time to do so. Nice walk though.
