You’ve changed the focus of the debate; we’re all well aware that local actions have local effects. My point is that, in the great scheme of things, whether I grow my own vegetables, buy from the local organic farm, or from the nearest mega-mart is irrelevant. I make that choice based on quality and convenience to myself and that decision has zero affect on anyone else’s quality of life. I am not advocating that we should ignore waste or live profligately, only that the environmental impact of most personal decisions is trifling.QUOTE]
Everybody I know lives locally, not “in the great scheme of things”. “The great scheme of things” is not somehow separate from what is happening in all the local areas. It is the sum of all the parts.
If you were the only person in a large area or the only one making a choice, then no, probably that choice doesn’t impact anyone’s life immediately. That changes with population density.
If you lived on 500 acres, for instance, your personal choice to play heavy metal full volume with the windows open at 3 am won’t have any meaningful impact on anyone else’s ability to sleep (might bother some animals, though

). Do that in a neighborhood
where the houses are on less than quarter acre lots or in an apartment building and suddenly your personal choices have a
very meaningful impact on a lot of others around you.
If one person decides to put a banned pesticide or herbicide on their lawn that runs off into a local creek that feeds the local water supply, it probably doesn’t make that much difference. If 300,000 people decide to do so at the same time into the same water supply, you are going to see an impact on the quality of the water for all the half a million folks who use that water, whether they used the substance on their own lawns or not.
I don’t believe that anyone on this thread believes that whether or not they individually take their own bags to the grocery store this Friday is going to change the course of the moon or cause the sun to explode. What I see from most folks is the knowledge that every choice is part of the cumulative effect, nothing happens in a vacuum, and that it is probably better to make those choices (whatever they are) as mindfully as possible.
There is no one size fits all template that everyone should be doing to be “good” or “moral” in this. I make plenty of choices that are based on quality and convenience to myself and there are folks out there who would look at some of those choices and sneer. I’d also appear inconsistent to some folks. However, I do my best to know
why I made those choices at any given time and to do so for a reason, not just let it happen.
