|It is a challenge to consume and not do harm|
Problem is, just hiking along is going to have some effect on other people and the environment regardless of how light one's backpack is. But that fact does not diminish my desire to minimize my impact as much as I can, and jettison some of the heavy stuff.
How am I contributing toward, or supporting, harmful practices? What I have learned is that the global economic machine makes it very, very difficult to avoid becoming just another cog that cranks out misery and mayhem.
Henry David Thoreau, in On The Duty of Civil Disobedience, said "Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn."
A no-nonsense way for me to be a counter-friction to the clanking, wheezing gears and cogs of consumerism is to simply consume less.
Reducing consumption reduces harm.
