I'm already happy when I reach my callorie intake goal for the day.

Also, like 75% of emissions are from energy according to Our World in Data. With livestock being around 5.8%. (+1% energy from food & tabacco)

Sound like we need to focus on cleaner energy, and no, windmills aren't the way with the amount of space and maintainence for the energy produced.

I'm sure you'll find another source with different numbers, this is just my take and a quick search.
