On Pesah we begin counting the Omer, a 49 day period to Shavuot, we can have as an Omer practice becoming more conscious of our consumption patterns, perhaps not buying any new non-consumables (things that we do not use up, i.e. food is a consumable,  clothing is not).  During the Seder we will sing Dayenu- it would have been enough. This is good time for us contemplate how much stuff is enough.  We can use Pesah for the cultivation of a new sense of freedom from a culture of constant consumption.
