Our Vision & Mission

But seriously, why
plant-based & zero-waste?

Short answer: save lives, eat plants.

Three reasons. Each one enough on its own.
Together, they are everything.

Animals Planet People
5,000 Animals slaughtered every second, 24/7/365
80% Of rainforest deforestation caused by animal agriculture
42% Of US cropland currently fed to cattle
92% Of freshwater sources that could be spared
1

first & foremost: our fully sentient family & friends

Animals

Our fellow Earthlings: a unique collective of co-conscious individuals

Liefs was launched to create a kinder world, for everybody we share this precious planet with. We believe animals are here with us, not for us.

Though we may not sound, swim, slide, soar or seem the same, we are similar in all the ways that matter.1 We all share universal and timeless instincts such as love and fear.2 There is a growing abundance of science supporting their sentience and even congruent complicated characteristics such as culture, altruism, and mourning.3,4,5

Yet, all it takes is empathic observation and your good old gut feeling to understand our fellow fluffy, furry, feathered and finned Earthlings are more than mere objects for entertainment, experiments, fashion or food.1

As food contributes to over 95% of animal suffering, by slaughtering some 5,000 souls per second, 24/7/365, the major key to a kinder world is one meal at a time.6,7

There Is No Planet B (for now... and even if!)

Planet Earth, our home, our place

Adopting a plant-based lifestyle is the biggest contribution humanity can make to an environment that's healthiest for all of us.8

There's no planet B (for now) so let's treat her like that. And even if there is one, why not still try to treat her right by eating plants to save lives? 42% of US cropland (now fed to cattle) could be retained, 80% of rainforest deforestation halted, 92% of freshwater sources spared.9,10

Ending animal agriculture is the simplest solution to the world's biggest challenges: climate change, ocean acidification, ocean dead zones, deforestation, biodiversity loss, water waste, world hunger, obesity, diabetes, antibiotic resistance, heart & coronary diseases, zoonotic diseases and animal cruelty at a global industrial scale.11,12,13,14

That is why Liefs’ mission is to ‘promote plant-based products to normalise conscious consumption’.

Your Health, your other home

People

As beautifully full circle as Mother Nature’s planets: eating healthy is healthier for her and her animals too

Even though our bodies have evolved to tolerate moderate amounts of animal products, we do not need them to survive.15 Better yet, a growing amount of long-term, independent, peer-reviewed scientific studies conclude we are healthier without them.16,17,18

Whether it's our immune system, various enzyme systems, carcinogens, hormonal activity, insulin, brain function, heart and arteries, people whose diets are high in animal protein have significantly higher rates of chronic disorder: hypertension, cancer, diabetes, heart disease, cataracts, diverticulosis, inflammatory bowel disease, gall bladder disorders, gout, kidney stones, and rheumatoid arthritis.15,21,22,23

Thousands of original studies and hundreds of meta-analyses conclude animal products and protein are linked to chronic disorders and premature death.17,18 Cancer is clearly and positively linked with eating animal foods.19

Even conservative institutions like the FDA, the American Dietetic Association, the British Dietetic Association, and Oxford University recognize and recommend plant-based diets as healthy in all stages of life.15,20

Isn't it beautifully wholesome that doing well to the animals and our planet, also seems to do well to our bodies?

Why vegan, human health benefits of a whole-food plant-based diet

FAQ * Frequently Asked Questions

‘What about protein?’ Common myths on veganism debunked

From B12, iron & soy, to almonds, bees, the Amazon & beyond

People

Where do vegans get their protein?

Legumes, tofu, tempeh, whole grains, nuts and seeds. A varied plant-based diet provides all essential amino acids.

Is plant protein inferior to animal protein?

No. Muscle growth depends on total protein and training, not the source. Studies show equal strength and muscle gains.

What about vitamin B12?

B12 is made by bacteria, not animals. Farm animals are usually supplemented with it too, so vegans simply take it directly.

Can vegans be athletic and build muscle?

Yes. Plant-based athletes compete at elite level in endurance, strength and power sports.

Is veganism bad for bone health?

No. Bones need calcium, vitamin D, protein and weight-bearing exercise, all available on a vegan diet.

Do vegans lack iron?

No. Legumes, whole grains, seeds and greens are rich in iron. Vitamin C boosts absorption, and the body regulates plant iron more safely.

Is soy harmful or estrogenic?

No. Human studies show soy does not feminise men or disrupt hormones, and it is linked to a lower cancer risk.

Planet

Isn’t regenerative animal farming the answer?

No. Regenerative grazing still uses more land and water and emits more methane per calorie than plant farming. It cannot feed 8 to 10 billion people.

If everyone eats more soy, won’t that destroy the Amazon?

No. About 75% of global soy is grown to feed livestock. Eating soy ourselves reduces deforestation.

Don’t local, organic eggs and meat have a low impact?

Not really. Most emissions come from the animals themselves; transport is a small share. Even small farms use more land and water than plant foods.

Isn’t almond milk worse than cow’s milk for the planet?

No. Per liter, dairy uses more water and land and emits more greenhouse gases.

Animals

Why is honey not vegan? Don’t bees give it to us?

Bees make honey as their own winter food. A worker bee makes about one twelfth of a teaspoon in her lifetime. Harvesting it stresses the colony, and queens often have their wings clipped to stop them leaving.

What’s wrong with backyard eggs?

Selective breeding makes hens lay 250 to 300 eggs a year, draining calcium and causing weak bones and reproductive disease. Most hens come from hatcheries that kill male chicks.

What about eggs or milk from local, organic family farms?

Standards vary, but the animals are still used, controlled and killed once no longer profitable. Exploitation in a nicer setting is still exploitation.

Isn’t meat humane if the animal had a good life and a quick death?

Taking a life when it is not necessary is still violence. Farm animals are killed young, as soon as they are fully grown, because keeping them longer costs money.

But don’t animals kill each other too?

Yes, but a lion kills to survive. We have other options.
