        livestock production in the UK and Ireland is still linked to rainforests abroad since chickens, pigs and cows are often fed imported soybeans. Brazil is the world’s largest soybean exporter, and much of its crop is grown on deforested land.

        Many people might also be surprised to learn that Ireland and western regions of Great Britain are home to rainforests: temperate forests sometimes called Celtic or Atlantic rainforests. And, like their tropical counterparts, UK and Irish rainforests are threatened by grazing livestock, particularly deer and sheep.

        If it is anything like here they supplement the feed with a ton of soy beans, which is causing huge problems in Brazil. iirc 87% of soy is used for cattle.

        Just globally. Not sure about specific countries. Virtually all of the Amazon deforestation, for example

            We can’t have more cows if they don’t have food. We need to cut down trees to grow other stuff to feed the cattle. Global demand for beef is rising, mainly due to increases of standards of living in Asia.

            So how do we raise more cattle without more farmland to grow food for them?
