Is Veganism really the answer?

Depends on the question, doesn't it?

I'm vegan because the workers in the blood industry suffer both workplace related and psychological trauma from working in slaughterhouses. Not only are they treated badly by management, but being surrounded by so much suffering and death actually causes incredible psychological harm to the people forced to do this kind of work. Killing always takes a toll on the mind because we're empathetic apes - on an industrial scale it's simply inhuman.

I worked at a chicken hatchery when I was in high school.. we would hatch about 150k birds twice a week (Tues and Fri, typically). My step-dad was the manager so I was a “whatever you need right now” employee. Did nearly every task there other than things you need specific licenses for, or killing.
We only shipped female chicks, so they were sexed and the males were killed.
They were supposed to be plunged into ice water to shock them before they drown, supposedly that’s better, but due to the volume we went through (~70k killed per hatch day) and the fact that the temp inside in summer got well over 100 degrees (f) due to the incubators and hatchers, it was never colder than tap water.
That was back in 2004, and I still remember the guy who did the killing. He was super fucking creepy and weird and we were pretty sure he enjoyed it. The rest of us gave him wide berth… and I tried to avoid going anywhere near where they were killed because it was horrific. I won’t go into detail, but whatever you are thinking, it’s probably worse.
They were then turned into mink food. Dunno what we need to farm mink for, but whatever.
It took like 15 years before I could stomach eggs, and I only forced it because it’s cheap protein and I can get them from locals rather than factory farming, or raise my own fowl humanely (free range as friends, neutral gas asphyxiation for slaughter when it comes time. Humane as death gets and what I want for myself - we know it feels like almost nothing because people pass out from it all the time, mostly helium, and there have been some notable casualties which led NASA to add iirc 6% co2 to un-oxygenated nitrogen-filled chambers so people felt themselves suffocate before collapsing)
- I'm so glad egg substitute is available, sometimes I really want huevos rancheros or potato shipwreck and I don't know any birds personally to get eggs from. I miss egg whites, though. Substitutes are basically all yolk-ish
  As for flesh, at most I'll eat bugs. Bumblebees taste like bacon!
This, and also the suffering of the animals. The whole situation is absolutely miserable, and anyone who witnesses it will feel that.

Its part of it, but remember the consumer is not the only one responsible. The deregulation of corporations and lobbying against ecological efforts, paid for by corporations, and enacted by politicians and protected by police are a big part of the destructive side of capitalism and consumerism.

It’s one of them.

I'm glad that many comments on the video highlight the ethical aspect.
