I have decided to start keeping track of how many Zeroes I am able to accumulate in a day.

My "Zero Day" is not the same as the hacker zero day concept.
Instead, my Zero Day has to do with Reduce, Reuse, Recycle.
There's a lot of talk and action about recycling. Much less on the reduce and reuse side, which is understandable but lamentable.
Understandable: recycle is post-consumptino, reduce and reuse and pre-consumption. The more we reduce consumption, the less people consume = buy, and human economies are structured entirely around perpetual growth.
So corporations are all fine with promoting recycling, not so much reduction.
But I am convinced, and feel it is quite obvious, that the only way out of the terrible mess we are making of our world is for each of us, individually, to reduce our consumption as much as possible.
And you can't reduce lower than zero consumption. So I am going to see how well I can do at achieving some zeroes each day in my life. 
Here's what I am going to track on my Twitter account:Zero use of my carZero consumption of plastic (plastic bag for groceries, for example)Zero purchasing of processed foodZero purchasing of anythingZero seconds spent watching televisionZero drinking of water from plastic bottle (thanks, Rob!)I am sure I will think of more - and will add to the above list as I do. Do you have other consumptions?

P.S. I am also trying really, really hard to only eat when I am hungry. So far I have lost 5 pounds in the last week. I hope that trend doesn't continue. :-)
