In 30 years from now, what will we eat? Will the food still be the same as it is now?
The United Nations says that there will be over 9 billion people in the world by 2050. Our food needs will grow by 70%. What we eat now may not be enough for humans in the future. That is to say, we'll have to turn to something else. But what else can we eat? Here are a few possible choices.
Veggie (Vegetable) meat — A new kind of hamburger is now popular in the US. It looks the same as any other hamburger, and so is the taste. But it's actually a "beef" burger made out of plants. The company behind the burger, Impossible Foods, uses peas and potatoes to make the "beef". They take coloring, protein (蛋白质) and fats from these plants and mix them together.
Making meat out of plants uses less water and land than raising animals for meat. It also creates fewer green house gases. Some food companies are making chicken, pork and other meat out of plants, too—follow the same steps as making the "beef".
Insects — Insects take up little space and don't make much waste. They also have more protein than beef, chicken and pork. This makes insects another possible food of the future.
It's common for people in some places to eat whole insects. But most people probably won't want to see the insects they eat. So in the future, people will first turn insects used for food into powder (粉末). Then they can use the powder to make other foods like chips, protein bars, biscuits and so on.
Algae — The BBC says algae farming could become the world's biggest farming industry in the future. They point out that algae is cheap and grows very quickly. Also, it's very nutritious (有营养的). It has much more protein and oil than many other plants.
Besides eating algae as a dish on its own, people may also use algae oil and algae butter in the future. Some algae has a strong taste. The UK scientists are trying to use algae to take the place of salt.
