要保证我们星球上几十亿人口有营养价值丰富的食物,消灭饥饿,特别是由于缺乏蛋白质而引起的饥饿,这是困难的,非常困难!但是有一个简单的解决办法——合成食物。而要制取合成食物,必须简化食物链环节。有一门科学叫“生态学”。它的研究历史不长。这是一门研究自然界存在的诸系统的科学。食物系统便是其中之一:太阳能——植物——动物——人。人吃动物的肉;动物吃植物,植物生长靠太阳能。这四个环节组成一个食物系统,也叫食物链。这个天然的食物系统效应是很低的。作一个设想,有一个小孩整年(从12岁至13 It is difficult and very difficult to ensure that the billions of people on our planet have nutritious food that eradicates hunger, especially hunger caused by a lack of protein. But there is a simple solution - to synthesize food. To make synthetic food, we must simplify the food chain. There is a science called “ecology.” Its research history is not long. This is a system of science that studies the existence of nature. Food system is one of them: solar-plant-animal-human. People eat animal meat; animals eat plants, plants grow on solar energy. These four links form a food system, also called the food chain. The effect of this natural food system is very low.
