Needlessly large vehicles moving one person A to B are wasteful. If a larger vehicle is hauling a load as intended, excellent! On rare occasions, I envy the usefulness of a pick up truck, when I need to carry something too big for my car to carry. All the rest of the time, I appreciate the great mileage my diesel VW gets - getting me from A to B alone. That said, I did carry a Honda riding mower with me from A to B once, entirely inside the car, without damaging anything, and it was not as high to load as a tailgate would have been! And I moved it 100 miles with about two gallons of fuel....
Personal transportation is a small part of fossil fuels being used and wasted. When the VW diesel emissions scandal became public a number of years back, I was in Europe, meeting with two of my clients, German atmospheric research scientists. We laughed over breakfast, as all three of us drove diesel VW's (and I still do). They told me that they had been aware of this "cheating" on VW's (and other lesser publicized auto manufacturers as well). They told me that 11 million VW's were affected by this worldwide. And the total exhaust emissions of those cars was about equal to the emissions from ten of the largest ocean going freighters. So cars and trucks are a part of the problem, and a part we can each take some personal responsibility for. But, buying locally, and not shipping containers around the world will help a lot too!
I put new hardwood floor throughout the house a few years back. Being Canadian, I specifically chose "product of Canada" hardwood. Loyalty to my fellow Canadians and less shipping - to find out to my great disappointment later that the wood was indeed harvested in British Columbia (so product of Canada), then sent to China for milling and finishing, then sent back! That product not only contained mostly non Canadian labour, but crossed the ocean twice for no good reason! I will shop more cautiously next time. Some stuff seems to have to come from Asia, so be it, but not everything does! I choose!
As side note about moderation: I do not moderate here, I'm a guest. I do moderate elsewhere as an unpaid contribution to it being a better "place" for the guests. Sure, some guests figure that what they have to say is important, and should be entitled to be read by everyone else as free speech. Sure, they're free to speak - but, the website is a privately owned place, and the owner is entitled, and indeed required by legal implications, to prevent some kinds of speech, let alone, simply preventing a post from offending other posters. We all have different perspectives on what's okay to post, hey, I've had posts I have made as a moderator, removed by another moderator a couple of times, no one is perfect. But, you'll find that an unmoderated chat site will not attract discussion which most people like. Moderators apply their effort to make it a better place out of a sense of care ('cause there's little or no pay!), so do Moderators a favour and respect their efforts. No moderation is perfect, but on the whole it makes a site you're happy to recommend to others....
