What do you understand by the new technology namely refrigerated ship?

The trade in meat offers a good example of this connected process. Till the 1870s, animals were shipped live from America to Europe and then slaughtered when they arrived there. But live animals took up a lot of ship space. Many also died in voyage, fell ill, lost weight, or became unfit to eat. Meat was hence an expensive luxury beyond the reach of the European poor. High prices in turn kept demand and production down until the development of a new technology, namely, refrigerated ships, which enabled the transport of perishable foods over long distances
