I think your math is wrong, most websites I see say 7 or 8 trees produce all the air you breathe, so that’s perfectly reasonable.
Offsetting the rest of your consumption is another thing, but not something a single person can do. An average person doesn’t personally produce a crazy amount of CO2, it’s industrial and excessive consumption that does the bulk of it.
Depends on what you mean by “all required minerals, vitamins, etc.”
If you are including all proteins, fats, and calories, then nothing happens. (assuming you didn’t miss anything at all)
If you exclude any required “etc” then your body will try to keep you in homeostasis for as long as possible, depleting any reserve unit it can’t anymore.
If you’re short calories, then your body will process fats and muscle and you will get leaner until it can’t manage.
If you’re short protein, then your body will process muscle and you’ll lose strength until it can’t manage.
If you’re short calcium, then your body will process bone until you break something.
Probably, without a very careful regiment, with blood work and doctor’s supervision, you’ll end up with a deficiency of some kind and could cause permanent damage.
