Forgacs starts by explaining just how costly a single quarter-pound beef patty is to produce. For that one serving, 6.7lbs of grains, 600 gallons of water, and 75 square feet of grazing land were used. Now multiply that by 1000 to find your (approximate) impact — the average American eats over 220lbs of meat each year. Additionally, at least 18% of greenhouse gas emissions are due to meat production. All this for one burger?
If 3D printed meat could one day (hopefully soon) become an economically viable and tasty alternative to the real thing, humanity will have taken a massive leap forward. I hope for this day to come soon.
