A skyscraper in China can slaughter 1.2 million pigs a year. The biggest pig farm in the world is in China, according to The Guardian.

The country's growing demand for pork is one of the reasons why it is located on the southern outskirts. Half of the world's pork is consumed in China.

More than 600,000 animals will be housed on the farm-in-the-sky, according to statements on the company's account analyzed by The Guardian. The total cost is about $557 million.

According to the Guardian, the 2.6 million sq foot farm has advanced technology. The pigs' waste is used to generate heating and power and the animals are fed via buttons.

3,700 sows have been sent by the company behind the development.

A farmer who lives close to the skyscraper shared his thoughts with the outlet. We used to only have a few pigs in our backyard pigsty.

Back in the day it would take us about a year to raise a pig, and now it can be done in a few months. He believes that this will be the trend in the future.

Workers may have to stay on-site for a week at a time if the company's statements are to be believed.

The pig farming industry is headed towards a highly automatic and intelligent future, and the standards and threshold for pig farmers will become higher as a result.

Some experts were concerned about disease outbreaks.

Matthew Hayek, an assistant professor in environmental studies at New York University, told The Guardian that intensive facilities can reduce interactions between domesticated and wild animals, but if a disease gets inside, they can break out between animals like wildfire.
