So there is a family that spend only 350$ on food a month. They say they look for bargain around the grocery store using walkie talkie.

For example if they found some cheap meat that gonna expire tomorrow they buy [maybe a lot] and then freeze it so it can last longer

But using too much meat create more global weather change than transportation according to UN research.

Then if they vegetable from Peru because is cheaper are they accounting for the energy spent for transportation also.

Or if they buy mineral water or are they using tap water?

What about shoes? Are they used or new? Usually cheap shoes are from China where democracy is still a dream for millions and create pollution [but who care we are saving money]. No?

What about computer? Better a cheap dell than a mac? Save money but not energy to operate or stress to use it.

That all matters, here and now. Consequencies we ll deal later.
