1 . Climate breakdown threatens to cause a global food production crisis. The UN forecasts that by 2050, feeding the world will require a 20% expansion in global water use for agriculture. It is hard to see how agriculture can feed the population of the planet, let alone toward the end of the century and beyond. Agriculture is a major cause of climate breakdown, and both river and air pollution. Industrial fishing is similarly driving ecological collapse in seas around the world.

However, at this critical time, farming (a new kind of food technology) is creating astonishing possibilities to save both people and the planet. Farming will enable the return of vast areas of land and sea to nature, greatly reducing carbon emissions (排放物). It means an end to the employment of animals, a stop to overfishing, and a dramatic reduction in cutting down forests and the use of pesticides (杀虫剂). It is the best hope for stopping the destruction of the planet and, if it is done right, it means cheap and abundant food for everyone.

We are about to welcome one of the biggest economic transformations, of any kind, for 200 years. Arguments continue about plants against meat-based diets; however, new technologies will soon make these arguments irrelevant. Before long, most food will come neither from animals nor plants, but from micro-organisms (微生物).

Not only will food be cheaper, it will also be healthier. Due to the fact that farming creates food products built up from simple components rather than broken down from complex ones, hard fats and other unhealthy components can be screened out. Meat will still be meat, but it will be grown in factories rather than in the bodies of animals. Fats will still be fats, but food is likely to be better, cheaper and much less damaging to the living planet.
