First of all, we waste a lot of food, so reducing that would help get part of that 0.2% carrot. The figures hardly support weight loss as a solution, but even if it were, we couldn't do it. Every time we've faced a major issue, "do less of the bad thing because it helps directly solve the problem" doesn't work. We do the bad thing because it's something we find valuable, and each one of us doing it doesn't add terribly much to the heap. Note I'm talking about tragedy of the commons type issues. Not smoking really does help the individual not get lung cancer, and people did it. What works is when new tech is invented/expanded: - Drowning in horse poop? "Ride your horse less" didn't work, inventing cars worked. - Bad air quality? "Use your car less" is hard when it's so useful to drive to places. Then someone invented catalytic converters. - Ozone layer hole? Was the answer to use less cold storage? It was non-CFC fridges. The same is true with our CO2 issue. Telling people to eat less, fly less, drive less, etc just ain't gonna work. The thing to try is to invent our way out of it. Fusion, solar, electric transport, batteries, and a bunch of others are what we need, and it can't go fast enough. Techies have bailed the world out of every shitty situation ever (yes including sewer engineers) and if we get out of this one it will be techies who are to thank.
