I feel better about limiting the size of my drop in the bucket than I would feel about just saying my drop doesn't matter even if it doesn't matter. I get my internet through my phone's hotspot with its 15gig a month plan, I generally don't use the entire 15gigs. My phone and and laptop are pretty much the only high tech I have, audio interface is probably third in line and my oven is probably fourth (self cleaning). Furnace stays at 50 all winter long even when it is -40 out and if it is above freezing the furnace is turned off. Never had a car, walk and bike everywhere including groceries and laundry, have only used motorized transport maybe a dozen times in the past decade.
A nice side effect of these choices is that I only spend a small part of my pay. Never had a credit card, never had debt, just saved my money until I had enough that the purchase was no big deal.
I don't really have an issue with people who say that their drop does not matter so why should they worry, but I don't understand it, seems like they just needlessly complicate their life. Not too long ago my neighbor was bragging about how effective all the money he spent on energy efficient windows, insulation, etc, was, he saved loads of money that winter; his heating bill was still nearly three times what mine was despite using a wood stove to offset his heating bill, my house being almost the same size, barely insulated and having 70 year old windows. I just put on a sweater instead of turning up the heat.
Edit: Sorry about that sentence, not quite awake yet and doubt I will be awake enough to fix it before editing window closes.
