was they were quite radical.

I pictured hippies with tie-dye shirts.

i love this stuff!

But it's rapidly becoming mainstream.

A lot of people still find it surprising

that you can be a champion boxer and be a vegan.

I love that I can challenge that.

i don't think there's many Muslim vegans around.

I haven't met one yet,

but I really want to change that.

Some people think it's pretty weird to be vegan,

They're like, is it annoying?

And I go, no, no. I want to be vegan.

I just think it's going to save the world.

Soon, everything might be gone,

like, I think it's from cow farts of something.

Hi I'm Amanda Brewer, I'm a stay at home mum.

My husband and I have three kids and three dogs

and we're all vegan.

This is my pantry -

and it's a traditional Australian looking pantry.

Even the Vegemite is vegan.

I thought that with having my children and breastfeeding,

animal products were something that I needed.

I came across information from very credible sources,

like the World Health Organisation,

that eating animal products and meat

was perhaps not the best way to go.

The initial challenges for me were,

so I can't eat chicken, so I can't eat cheese.

it wasn't until Amanda was asking me, watch this documentary Cowspiracy.

Animal agriculture - raising and killing animals for food

is really what's killing this planet.

So from then on, I was like, I can't do that anymore.

So two cups of cashews...

Ice cream was a bit hard to give up

until they made vegan ice cream.

I was like, yes!

We've got it in the fridge right now.

Guys, who wants to help me feed the dogs?

Me!

We feed our dogs human grade food,

and it's a very scientifically planned well-balanced diet.

- Can I eat it? - I don't think so!

We did the research into, is this cruel? Not giving our dogs meat.

I know that one of the oldest living dogs in the world

was on a vegan diet.

I think children instinctively love animals.

and so for her she's become this fierce crusader.

Someone had a ham sandwich at school,

and I was like, but that's an animal's life!

How would you feel if you were that pig?

And then the mums get really upset.

I've had to try and explain to her

not to ram it down people's throats,

because you've got to keep your preachiness in check.

Sometimes people don't want to sit next to me

because they think it's weird that I'm vegan.

Some people think I'm going to die when I'm 11.

But I'm like, I'm not going to die.

I might become the longest living person,

being vegan at this age.

There's definitely the misconception out there

that vegans are weak, they're not fit,

they can't build muscle mass.

I love surprising people.

I'm Claire Foreman,

I'm the WMC Australian bantam weight champion.

I've been vegan for about a year and a half now.

Since going vegan I won my Australian title.

I've won six straight fights.

I didn't think that would happen, going vegan, but it has.

I think there's so much dogma in the fitness industry

that you need excessive amounts of protein

and that protein has to come from animal sources.

Personally I have found that by eating more carbs

and more of a variety of foods

that I've been better able to build muscle.

My recovery time is really quick,

and recovery time from injuries as well.

A lot of people say it's because of the high antioxidants

in plants, and the high amount of micronutrients as well.

If I have to answer the 'what about protein' question one more time...

This gym has become a bit of a vegan hub.

Everyone gets ripped on coconut water.

Like they look up to the fighters,

so if you've got fighters there that

are performing well, and they're really strong and fit

and people are asking them, what do you eat,

people are quite inspired by that, I think.

We all tend to cook very good shit.

and feed it to all the meat-eaters, they're like what is it?

and you're like, it's plants mate.

How good is that?

What are you cooking, mum?

Are you going to add meat to it?

Of course I'm going to add meat to it.

I grew up eatiing a lot of meat, dairy and eggs,

and for dinner it was kebabs most nights.

It's a massive part of my culture.

my name's Abdullah, I'm 23 years old

and I came as a refugee from Afghanistan when I was eight years old.

We came here because we were scared for our lives because of the Taliban.

My dad used to be an artist in Afghanistan.

and they came and they smashed all his paintings

and they beat my mum up in front of me.

So I feel like having witnessed things like that

it's made me more compassionate as a person today.

I spoke to two Muslim girls yesterday

and they thought halal was humane.

How is it humane?

I think my parents didn't understand how

I could change the way I ate so dramatically.

I never expected to go from becoming a vegan

to becoming a vegan activist.

We head out every single weekend

we hold massive screens

showing the public what actually goes on in our agriculture industry.

The footage that we show on our TVs

is standard Australian practices

that's happening everywhere.

It's the majority of what's happening out there.

I don't think people consciously contribute towards the cruelty in animal agriculture.

Like most people don't actually know what's going on.

People use words like organic dairy

or happy farm - stuff like that.

But they don't actually realise that at the end of the day

all these animals are going to the same slaughterhouse.

Okay guys, come up to Cow Sanctuary.

You're going to meet 77 residents here.

I'm Anthony Wallscot

and I founded the Save A Cow sanctuaries. in 2010.

I rescue and save cows

from sale yards, from dairies.

Get bobby calves before they're hit on the head.

So Save A Cow is about providing sancturary

for the term of their natural life.

The greeting for cows is actually like this

and then you put your nose out.

I run public events.

When people come and see the personalities of the guys at the sanctuary,

they're conflicted

because that no longer can they deny that

Bunty Heart is not a machine.

He's a living being with feelings and emotions

and he communicates.

If humans spent time in a sanctuary like this,

they would realise how incredibly individual each resident is.

They themselves then become advocates

for their freedom in the future.

It's quite an intimate thing to be that close.

You know, they're wanting to connect as well.

There's also a brochure about the health consequences.

It's important not to turn people away.

So when we have discussions with them

we don't just attack them.

Think about it - it's no good, man.

No, I never had any idea it's happening like this.

Some people even go vegan straight on the spot.

and they tell us they're going to do vegan.

I'll give it a go - definitely.

It is a growing trend.

We're going to see more and more vegans in the future.

Absolutely.

It's good for the world, it's good for me,

it's good for the animals,

it's going to be good for everyone else,

so I think it would be better. A world of vegan people.
