The most environmentally friendly food to eat is the food that you grow locally in your back yard or purchase from your local farmer's market. *(I know that not all food is grown organically or sustainably) but by purchasing locally, you are cutting out many fuel CO2 points. Second, eat lower on the food chain.
Meats take anywhere from 1.5 to 7 lbs of grain per finished pound of meat to produce. Meat production requires vast amounts of fuel consumption from start to finish. Fuel must be used to grow the grains, make the fertilizers, ship animals to market, refrigerate meats, ship meat to local market etc.If you eat meats, find a local grower and have your meats packaged in your near area.
If you garden you may actually help the environment by adding compost to your backyard garden plot. This compost boosts the soil and restores the soil to a better state than if you did not add compost. Compost is made from fall leaves, grass clippings, kitchen waste, shredded cardboard or newsprint.
Organic foods that are produced without using pesticides and fertilizers are environmentally friendly food which is palpable.
I would say pasture-fed, free-range meats. There is no grain involved, so you can wipe that whole money and CO2 part away. There is very little petroleum involved--just what it takes to get the animal to the butcher, and the meat back to the buyer or farmer.
There are excellent, necessary fatty acids and fat-soluble vitamins in this kind of meat that are not present, or are only present in a form that must be converted, in other foods. In addition, eating high protein meals--particularly a high protein breakfast, as opposed to a typical high carb breakfast--suppresses the appetite throughout the day, so you actually end up eating fewer calories.

I've bought 100% grassfed meat this way for the last 4 years, no further than about 30 miles from my home, for about $3-$5 per pound, complete cost. Quite a difference from paying upwards of $10 a pound for similar meat in natural food stores, who had to truck it in!
Farm fresh fruits or vegetable grown through organic farming.
Vegetables are some of the most environmentally friendly things you can eat. You might find the link below very interesting.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
