As unethical as eating soy from a deforested area. Or eating mostly anything with sugar, canola oil or palm oil. But people don't ask those to be in non deforested areas, and they don't ask to increase the price to make sure soil is not destroyed by monocrop cultivation.

[nicoburns]

That's not entirely true. There is a whole movement around boycotting palm oil for example, just as there is with beef. It certainly could be more widely supported.

It's worth noting that a lot of the soy from deforested areas also goes towards feeding livestock. The soy that humans eat (or drink) tends to be more more ethical on average.

Not because of deforestation, but because threats to orangutans.

Most of the food animals eat is not human-grade, and a big part of it are by products of food for human consumption it would not be used anyways.

Food grown in deforested rainforests often isn't human grade because, stripped of the natural forest ecosystem, the land often doesn't have the nutrients to support high-quality agriculture. Don't you think pretty awful that we destroy some of natures most important ecosystems to make room for poor quality agricultural land?

It seems to me the scenario really would like

1. Deforest land, for some purpose at most tangentially related to agriculture (presumably to use the wood)

2. Land becomes fairly useless; find most productive usage possible

3. Animal agriculture / grazing fields

That is, I doubt land is being specifically destroyed for this purpose -- there's enough available land to simply use as-is... unless it's already been destroyed as a byproduct of other activity.

For reference, only about 6% of soybeans grown worldwide are turned directly into food products for human consumption.[0] Most goes to feeding animals that are used for human consumption.

Exact. Soy monocultures are devastating for environment, is an evil league respect to pastures, that still hold thousands of species. Soy fields have one species for Km and Km. Period.

[nicoburns]

Pastures in areas that are naturally grassy is fine. Pastures that have been created by deforesting the Amazon are not at all ok (Brazil is the worlds largest exporter of beef - not all of that is Amazonian land, but a lot of it is).

Soy is often grown in deforested rainforest areas too. But as a sibling comment says, only 6% of soy goes towards direct human consumption. The rest is for animal feed.

Not really, though - the GP link says it takes 50 calories of feed to make 1 calorie of Beef, so eating the feed directly would require 50 times less land.

[tassl]

Let me doubt that assessment. That would be true if (1) the 50-to-1 was true (doubt it); (2) what we feed the cattle is human-grade food and (3) 1 calorie of a plant was as nutritious as 1 calorie of meat.

Sure but soy beans are about 10x-20x more energy efficient than cattle at feeding humans so much less deforestation. Skip the middle man and eat your veggies and beans.
