Each year, the world population increases by 70 million people. At this rate, the population will reach more than 9 billion people by 2050. As the number of human beings on our planet spikes, so does the demand for animal protein. But with 30% of the total land on earth already being used to raise livestock, the prospects of producing enough animal products to feed the entire population is looking bleak. Not to mention, the global livestockindustry already takes a huge toll on the environment. It depletes our planet of resources, pollutes the environment, and emits more greenhouse gases than the transportation industry. So if dialing up our livestockproduction isn’t a viable option, where will we turn for protein in the future?
