Eat local food that doesn’t get shipped far

True but not that much apparently, slow shipping is pretty dang efficient it turns out, and often more ecological than local greenhouses for the same plants. The biggest co2 impact is the “last mile delivery” to every point of sale, which is the same for local or internationally shipped foods.

There is more environmental impact then just co2, and its illogical to say food shipped around the globe doesn't have environmental impact. Plant based foods are bulky, so they take more energy to ship. Also, I hope you realize from this community you are not limited to plant based foods. Growing exotic plants that require greenhouses isn't eating locally, it's fighting nature which goes against the other green philosophy 'Learn to live in your local environment'

Reduce electricity consumption as much as possible.

Trueish, it depends more on the amount of renewable energy that you’re using.

Your making an assumption, perfect green energy still takes industry to build and maintain, plus every time you use electricity your generating waste heat. This impacts your environment.

Learn to live in your local environment without modern tools of comfort

I don’t think there’s a cave nearby, nor wild mammoths to hunt, so I’ll pass, thanks

Don't run heating or AC, learn to love natural breezes, channel your inner frank lloyd wright and be part of nature.

Be healthy and don’t get sick. Sick people are extremely environmentally expensive

Gladly but alas that’s mostly out of my control lol. Sure I’ll stay at home when I’m sick to keep from infecting others, but there’s not much I can do to keep getting sick except total isolation.

This IS in your control, the whole point of these metabolic communities is to make you aware of your metabolism and give you the tools to keep yourself healthy. Most medical expenses are for prolonged metabolic dysfunction. Keep your insulin low, reduce your carbs, live a active lifestyle, be healthly.
