Animal agriculture is the most destructive industry on the planet today. Here's why.
Climate Change
Global greenhouse gas emissions:
• 13% due to transport (road, rail, air and sea)
• 51% due to livestock and their byproducts
Livestock is responsible for 65% of nitrous oxide emissions, a greenhouse gas 296× more destructive than CO₂.
A person who follows a vegan diet produces 1/2 as much CO₂ as a meat eater.
Deforestation
1-2 acres (4,000-8,000 m²) of rainforest are cleared every minute.
Animal agriculture is responsible 91% of Amazon destruction.
Area of rainforest cleared:
• palm oil: 105 billion m²
• animal agriculture: 550 billion m²
A person who follows a vegan diet uses 1/11 as much oil as a meat eater.
Species Extinction
110 animal and insect species are lost every day from rainforest destruction.
Animal agriculture is the leading cause of:
• species extinction
• ocean dead zones
• water pollution
• habitat destruction
Fisheries
80.4 million metric tons of fish are pulled from the oceans each year.
(1 metric ton = 1,000 kilograms ≈ 2,200 pounds)
3/4 of the world's fish habitats are exploited.
For every 1 kilogram of fish caught, 5 kilograms of unintended species are caught and discarded as by-kill
(1 kg = 2.2 lb; 5 kg = 11 lb)
Water Use
1 hamburger = 3,000 liters of water = 2 months' showering
(1 liter ≈ 1 quart; 3,000 liters ≈ 800 gallons)
The meat & dairy industry use 1/3 of the earth's fresh water.
USA water use:
• domestic: 5%
• animal agriculture: 55%
A person who follows a vegan diet uses 1/13 as much water as a meat eater.
Waste
Waste from a farm of 2,500 dairy cows = waste from a city of 411,000 people.
Every minute, 3.2 million kilograms of excrement is produced by animals raised for food in the USA.
(3.2 million kg ≈ 7 million lb)
Land Use
1/3 of land desertification is due to livestock.
30% of the earth's land is used for livestock.
1.5 acres (6,000 m²) = 16,800 kg (37,000 lb) of plant-based food OR 170 kg (375 lb) of meat
Land needed to feed 1 person for 1 year:
• meat eater: 12,000 m² (3 acres)
• vegan: 675 m² (1/6 of an acre)
A person who follows a vegan diet uses 1/18 as much land as a meat eater.
