Question

Drinking milk every day is good for your health. However, if one day someone gives you a cup of cow-free milk, will you still want to have a drink?

Recently, an American company named Perfect Day surprised the world with its synthetic (合成的) milk. The milk looks and tastes almost like cow milk and has all the same nutrients (营养素).

The creators of Perfect Day are two young scientists, Ryan Pandya and Perumal Gandhi. Working in different cities, they didn’t know each other at first. But they shared the same crazy idea about making milk without the help from cows. They thought it would make the world a kinder, greener place. After they met, they started working on a way of making their dream a reality.

The secret to making cow-free milk? Yeast (酵母), 3D printing technology and old fermentation processes (发酵方法). They have developed a process quite like making beer. The two scientists also say their milk has longer shelf life than the real milk. What’s more, it’s delicious, safe and Earth-friendly. “We want people to enjoy our milk, while leaving a kinder footprint on the planet,” say the two young men.

However, they also know it will be a long way before people accept their synthetic milk.

Before people accept the synthetic milk, maybe we should do something to reduce waste. A store in Scotland is doing such a thing. It sells milk in a vending machine (自动售货机). The vending machine allows people to refill their glass bottles with fresh milk. “The milk vending machine lets us work with a local farm to get really tasty milk for our customers without wasting plastic containers (集装箱),” one worker from the store said. It helps to save the store about one hundred plastic containers a day.
