The IKEA Meatballs of the Future

When people think of IKEA they think of two things: affordable build-it-yourself furniture and meatballs. Using their iconic food offering as a base, IKEA's Space10 Research Lab has created a series of "Tomorrow's Meatballs" to illustrate what the future of food could look like 20 years from now.
The Space10 team explains on its blog that the purpose of the meatball project is to show the impact of the world's eating habits on the cuisine of the future. The resulting menu of six non-meat balls focuses on "alternative ingredients, technological innovations, and uncharted gastronomic territories" to offset what they call an "unsustainable appetite for meat." Space10 notes the many negative effects of that appetite (destruction of forests, soil erosion, disappearing fresh water supplies, etc.), citing a UN report which estimates that food demand on Earth will increase 70 percent by the year 2050.
