well that's from 2013? Do the claim still hold? I don't think there will be anything left to eat for vegan ? Why

See example of oil. There has been too many controversies regarding palm oil and how it destroys orangutan habitat. But now if we shift to olive oil which many people did there was a news of some bird being killed for that?

So the question is can we have 100% vegan? No for sure

But can we try to vegan as much as possible? Yes for sure.

And I will not eat the cashews from those company that are responsible for being horrifically cruel to workers. Same for palm oil and olive oil. We shall try for best.

There is no best method of faux cheese - it depends on your usecase.

That said, I do agree that cashew is extremely versatile.

you can google cashew mozzarella. They're all basically cashew, tapioca starch (makes it stretchy), flavorings (miso/nutritional yeast/etc), garlic, and a liquid (water/non-dairy yogurt/etc). The ingredients are blended, then cooked until it thickens.
