It's not just slaughterhouses that are a horror.  It's the way animals are caged all their lives before they're slaughtered.  I think, too, that everyone would be a vegan if they animals are put through and denied (like almost every instinct).

But the reason I bring this up is that I read in today's paper that Peet is ending its upcharge for plant-based milk, a surcharge I knew nothing about.  Paul McCartney had written a letter to Eric Lauterbach, president and CEO of Peet’s Coffee about the surcharge, saying he was surprised that Peet's was charging more for plant-based milked because "your company is committed to reducing methane emissions and water waste, yet cow's milk significantly contributes to them." .

But the reason I bring this up is because Peet's has ended its upcharge--an upcharge I knew o about--for non-dairy milk.
