A Vegan’s Impact: The Facts

As many people wrap up Veganuary and potentially weigh the pros and cons of sticking with it past the 31st, it’s important to fully grasp the impact that one vegan can have on the world.

It’s so easy to feel like just a drop in a huge ocean. Every vegan or temporary vegan must remember that even one person can make a huge difference for the animals and the planet.

Each day, a person who eats a vegan diet saves 1,100 gallons of water, 45 pounds of grain, 30 sq ft of forested land, 20 lbs CO2 equivalent, and one animal’s life.*


Whether you’re a vegan for life or you cut out the animal products one day here and there, you make a difference.

So much of our planet is used to support the meat and dairy industry that if most people were to go vegan, we could end world hunger and significantly shrink our carbon footprint. Think about that.

Here are some facts to digest:


5% of water consumed in the US is by private homes. 55% of water consumed in the US is for animal agriculture. 1

2,500 gallons of water are needed to produce 1 pound of beef. 2

1,000 gallons of water are required to produce 1 gallon of milk. 3


We are currently growing enough food to feed 10 billion people. 4

82% of starving children live in countries where food is fed to animals, and the animals are eaten by western countries.5

Worldwide, at least 50% of grain is fed to livestock. 6


Land required to feed 1 person for 1 year:
Vegan: 1/6th acre

Vegetarian: 3x as much as a vegan
Meat Eater: 18x as much as a vegan 7

Livestock covers 45% of the earth’s total land. 8

1-2 acres of rainforest are cleared every second. 9

Animal agriculture is responsible for up to 91% of Amazon destruction. 10


Animal agriculture is responsible for 18 percent of greenhouse gas emissions, more than the combined exhaust from all transportation. 11

Cows produce 150 billion gallons of methane per day. 12


70 billion farmed animals are reared annually worldwide. More than 6 million animals are killed for food every hour. 13

2.7 trillion animals are pulled from the ocean yearly. 14

These facts no doubt stirred some thoughts in your mind. Please share below. I’d love to hear your perspective.

  1. I am interested in a none meat diet but I’m not sure I could do it. I just started juicing and it is a super change in my diet. I still like pork. Truthfully I am considering going to baby food I just don’t have an appetite for regular food anymore. lol

    1. I would recommend smoothies! You can throw in whatever fruits and veggies you want so you can have a different combination every day. Smoothies totally changed my life. I didn’t used to enjoy eating all. I started on smoothies and found myself looking forward to them every day. They’re still my favorite part of the day. Do you have anything that you absolutely love to eat that is healthy and satisfying (and not meat)? Maybe just focus on eating that for a while. It’ll help you cut out meat and it’ll infuse some enthusiasm and joy into your meals. 😃


      1. I appreciate your encouragement and your confidence, but everyone also has weaknesses. And I know mine. There are several, so it takes a special ability to memorize long lists, but that is something I’m capable of. Going vegan, while I know it would be better for me, I’m just not capable. Have you heard the wonderful story of the frog and the scorpion? It’s a similar tragic tale.
