In an effort to alleviate food shortages and leave a lighter footprint, some biotechnology startups have begun developing alternative food products. Hampton Creek Foods, for example, has received $30 million in funding to create a plant-based substitute for eggs. Beyond Meat, another biotech food producer, heats, cools, and pressures plant protein from soy and peas so that it resembles meat tissue. In 2013, similarly, a hamburger was made from cow muscle grown in a lab — at a cost of $325,000.
