By 2050 there will be an estimated 10 billion humans living on this planet. Beyond that being a lot of mouths to feed, those folks will be, on average, wealthier than today's population, with a taste for the foods found in regions like the US and Western Europe. But we simply don't have the capability, the land or the production resources to ensure that many people can eat a cheeseburger whenever the mood strikes. Luckily, researchers from around the globe are working on alternative-protein sources to supplement our existing beef, pork and chicken.
Of course, there's tofu, which has been used as a meat replacement for thousands of years. But today's consumers expect their protein substitutes to closely resemble the meats they're replacing, which is why Impossible Foods and Beyond Meat have arrived to such public fanfare. These plant-based burger alternatives offer the same bloody sizzle that beef does. In Impossible's case, that comes from heme derived from soy roots that have been fermented in genetically engineered yeast. Beyond Meat, on the other hoof, relies on a processing method that "aligns plant-proteins in the same fibrous structures you'd find in animal proteins." But as much as they look, smell and taste like a real beef patty, these products are still extruded plant matter -- and highly processed products at that.
Julie Lesnik, a biological anthropologist at Wayne State University, advocates that we look to get our meat from smaller, more-resource-efficient animals than cattle -- specifically, crickets. She points out that per kilogram, crickets offer roughly the same amount of protein as beef as well as significantly more micronutrients, since you're consuming the exoskeleton as well.
Get ready to eat bugs if you want to live beyond 2050 | Engadget
I keep seeing these types of stories in my Twitter feed, from various news outlets I follow. We must switch from the protein sources we're accustomed to, to bugs! One of the many joys of globalism- in a world with 10 billion people, we'll get to live like people in third world countries have always lived. That means beef and pork aren't accessible to commoners. Oh well, a steady diet of rice and bugs should do much to curb obesity problems, and lower incidents of diabetes. Maybe we'll grow to love these new protein substitutes.
