The meat, dairy and egg industry is horrific
Some of it is, some of it isn't.
No animal wants to die, regardless of whether it's had a good life'.
You are applying human emotions to animals. Animals have no concept of relative deprivation or whether they have had a good life. If they aren't stressed or in pain they are pretty much happy.
There is no such thing as killing an animal humanely and these 'welfare standards' mean nothing to the animals. They still die a painful death which is totally unnecessary.
Yes you can kill an animal humanely and painlessly. Don't be ridiculous.
We breed millions of animals in to existence every year just to kill them
And it a our duty to give them a good life while they are here.
We give over 80% of all grain grown to animals for feed and if we fed this to humans, nobody would be hungry. There is plenty to feed the whole world a plant based diet.
Only if you MASSIVELY oversimplify how it works and assume all land is capable of growing grains (spoiler, it's not). Also, where's all the cow and chicken shit that's currently used to put nutrients back into the soil going to come from?
Deforestation is primarily caused by animal agriculture In some places. Not everywhere.
Animals are pumped full of hormones to make them fat as quickly as possible and keep them just well enough to slaughter. We are then consuming these as a biproduct of meat.
Not if you are in the UK you aren't. So either, you are knowingly misrepresenting the bad practices of some food production practices somewhere in the world and applying them to a UK based discussion, or you are in apple of fact checking and critical thinking and have simply believed all the anti-farming propaganda without doing any due diligence for yourself.
Our bodies are not designed to eat meat. Our intestines are for plants. I find it hilarious that some meat eaters will reference our 'canines' and talk about the 'food chain/circle of life' when I'd love to see said meat eater catch, kill and eat prey for themselves.
You know you are talking absolute crap here right? What's catching it yourself got to do with anything other than prove that early hunter gatherers literally progressed and evolved due to eating meat.
Instead, we go to the supermarket and purchase bleached meat packaged in plastic
That's awful. People really should try their local butchers instead.
after they have been killed by someone else, using tools the animal has no chance against
It's not a fight to the death. Can't even formulate a further response to this that doesn't involve references to opposable thumbs.
We talk about dogs being left in hot cars for 10 minutes at the supermarket but don't bat an eye over animals spending days and WEEKS in lorries and boats, covered in their own waste and without food or water - travelling to the slaughterhouse
Think about this, what kind of state do you think an animal left in these conditions for 'days, or weeks' would be in? It wouldn't be fit to eat. Why would anyone do that? It literally doesn't make sense.
I start getting upset if I know our fat lambs are going to be on a lorry for more than an hour or so.
Pigs are far more intelligent than dogs and have equal intelligence to a 3 year old human child. By nobody gives a damn about that because, bacon
Having kept both pigs and 3 year olds in the past, I disagree.
The dairy industry is the worst. They separate cows and calves (sometimes while still covered in amniotic fluid); just so we can consume the breast milk that isn't even meant for us.
Cows don't have breasts. They aren't chickens. Or humans.
The cows cries out for days and is distraught after carrying her baby for 9 months. Cows don't cry. Some might bellow for a bit, but also some don't.
The male calves are either raised in an isolation pen for 8 weeks
Here is an RSPCA fact sheet about calf hutches
www.rspca.org.uk/documents/1494939/7712578/Calf+hutches+v3.pdf/6f427dfa-465c-6b80-02f1-8855ea4997cb?t=1553271693737&download=true
For anyone that can't be bothered to read it, calves are kept in individual pens when they are really little to prevent the spreading of disease and stress. They must have contact with other calves the same age and at 8 weeks max they are moved into group pens.
and then sold for veal or killed immediately as they are no use to the dairy farmer because they can't make milk.
Your information is out of date. There's actually quite a healthy market for male dairy bullocks as meat. They are lean and increasing wanted by supermarkets for lean frying steaks etc.
The female calves are driven in to the same slavery and exploitation their mother has endured. When they can't produce milk anymore and/or are so emotionally traumatised and battered they can barely stand, they are lifted by cranes and taken to the slaughterhouse (they're called 'downers').
'Emotionally traumatised'. 
Yes downer cows is a thing. Doesn't mean what you think it does though and the vast majority of dairy cows don't end up that way. It's a system for humane culling unwell cattle on the farm.
The dairy industry IS the beef industry.
Yes. The two are intertwined.
We all celebrate breast feeding and the bond that is so important for mothers feeding their child (breast or bottle), yet we're literally ripping apart a mother and baby (who are sentient and have a strong bond) so we can put breast milk in our cereal and coffee. It's weird.
Cows don't have breasts.
The World Health Organisation have said that processed meat (including bacon and sausages) is a carcinogen.
Isn't that to do with the processing, nitrates added etc rather than the meat itself?
