l. 15 start-up company スタートアップ企業（革新的なアイデアを用いて急成長する企業）74 1 The world’s population is expected to reach 9.7 billion by 2050, and that is a lot of mouths to feed. Moreover, meat consumption is steadily increasing in emerging countries as living standards rise. Experts predict that the world could face a “protein crisis” by 2030. There will no longer be enough protein to meet global demand. 2 How can we solve this problem? It’s common to think of producing more meat to increase supply. However, breeding more beef cattle and pigs isn’t the answer because expanding livestock farming would increase the burden on the environment. For one thing, current livestock production requires vast amounts of grain and water. It takes ten kilograms of feed and 22,000 liters of water to produce one kilogram of beef. Livestock farming also requires farmland for growing feed crops and extensive grasslands for the animals to graze on, which leads to the destruction of forests. Considering this issue, we need to find alternative protein sources to meat instead of relying only on livestock. 3 One possibility is plant-based meat. Meat substitutes made from tofu have been around for decades, but now newer plant-based products are increasingly popular with health-conscious consumers.
