Animal husbandry has a large negative impact on the environment. After this DOW Grassland app I felt I needed to take a look at the environmental destruction I'm contributing to.
Except the alternative - ie, relying on annuals for food production - destroys top soil and relies on fossil-based fertilizers. It's the epitome of nonsusteinability and environment destruction.
Perennials combined with animals can be made into a much more self-sustainable cycle.
Be careful with numbers, they can be useful but fail to show the full picture at the same time.
Back when I was eating meat, I was probably still aware that it was harmful, but in a kind of cynical denial about it.
I've heard that one about "the annual crops" before, and it's simply not true that it's "the" alternative. It's claimed in this one study that's echoed in loads of articles[0][1][2][3] that assumes that vegans don't eat perennials, which is kind of ignoring the existence of apples, apricots, asparagus, artichoke, avocados, broccoli, currants, basil, blue- and blackberry, chives, fennel, garlic, ginger, grapes, kale, kiwis, leek, mint, onions, oregano, pears, persimmons, pineapples, plums, pomegranates, potato, rasp- and strawberries, radish, rhubarb, rosemary, sage, thyme, tomatoes for a start.
This view about animal husbandry being harmless for the environment has been disproven[4][5][6], and is on the line with global warming denialism.
It's not a question of being harmless but sustainable. Everything you do will harm or imbalance the environment somehow, the question is how much the environment can recover or if it can at all.
There are a ton of lines I could go to discuss your points, from "meat is not equal to beef" to "could one live healthily only on the things you listed?" (hint: no).
I see tons of articles with statements of journalists but no real evidence, if you want to discuss with references I suggest going to better sources. Actually, I suggest checking your references as well - this was written on [4]:
"[a major report into the environmental impact of meat eating claimed] eating some meat was good for the planet because some habitats benefited from grazing."
So yeah, even your references "disproving" what I'm saying are actually are actually agreeing with me to a certain extent.
Last, but not least, it's not about who eats what but about sustainable systems - either the system works as a cycle or it will eventually run off. You need to look at the bigger picture.
