4 Ways Meat Industry Is Destroying The Environment

4 Ways Meat Industry Is Destroying The Environment

Meat industry responsible for irreversible environmental damages, Cowspiracy reveals.

Until recently, oil and car industries were seen as the main culprits for climate change. But after an Inconvenient Truth, another documentary, Cowspiracy, has shaken common beliefs and changed the way we perceive global warming and sustainable practices. Read more about the effect of Cowspiracy in a twin-article United Academics published yesterday: A Steak A Day Keeps Sustainability Away.

The livestock production industry is now also publicly blamed for 4 negative effects on our planet:

 1. Land use


Livestock production is the largest land-use system on Earth. A report by the Food and Agriculture Organization (FAO) estimated that cattle industry accounts for one-third of the land surface use on the entire planet: one single cow can use up to 20 thousand square meters of land. The effects of over-exploration are already being felt: 20 percent of the arable land is now degraded due to over-grazing, compaction and erosion, as stated in the FAO repost above mentioned. [expand] The FAO report also states that land-use is now the major cause of biodiversity loss. In addition, deforestation affects water cycles, reducing infiltration and storage. [/expand]

At the same time, deforestation is a major concern, especially in Latin America. 70% of previous forested lands are now turned into pastures and fodder crops. For instance, between 1994 and 2004, the land area devoted to growing soybeans, mostly used to feed cattle, in Latin America more than doubled to 39 million ha. [expand] The WWF (World Wide Fund For Nature) organization states that around three quarters of the global production of soy is turned into soy meal which is used for animal feed [/expand]


Water resources are also being largely affected by the meat industry. The livestock sector is responsible for one-third of the freshwater usage on the planet and the production of one kg of meat can require as much as 20,000 liters of water, according to the UK’s Institute of Mechanical Engineers (IME) [expand] The IME also estimates that 30-50% of all food produced is ‘lost before reaching a human stomach'[/expand]

If these numbers do not impress you yet, the producers of Cowspiracy give us a little perspective: in the US, while private houses consume about 5% of the water resources, animal agriculture accounts for more than 55%. [expand] These and other facts, and it’s respective sources, can be found at the Cowspiracy website. [/expand]

3. Greenhouse gas emissions

The numbers related to the impact of livestock production on the atmosphere are also impressive. According to FAO, cattle accounts for 18% of greenhouse gas emissions measured in CO2 equivalent, a higher share than transports, for example.  But in this industry, CO2 release is not the major concern; livestock production is responsible for 37% of all methane and 64% of all ammonia emissions. [expand] According to the FAO report, methane is 21 times more effective in trapping heat in the atmosphere than carbon dioxide [/expand]

These emissions vary considerable between different animals. According to a study published in Pnas Journal, the production of meat and eggs from monogastrics animals, such as pigs or rabbits, has significantly lower emission intensities than milk and meat from ruminants, like cows or goats. [expand] The authors of the study estimate that emission intensities for global pork production are around 24 kg CO2 eq (equivalent) per kilogram protein, and for poultry meat and eggs, 3.7 kg CO2 eq per kilogram protein. [/expand]


Another disturbing aspect about the meat industry is the antibiotic over use. According to a report in the New England Journal of Medicine, more than 50% of the antibiotics produced in the US are used by the cattle industry on healthy animals. [expand] This report also states that over 80% of infections with salmonella are acquired from food animals. [/expand]

Antimicrobials are used by the livestock production industry as therapeutic agents for animal infections or, in the case of healthy animals, as a way of promoting growth and enhance feed efficiency. Antibiotics are administered through food and water and this ultimately reflects on the consumer: a recent study found that about 80% of supermarket meat in Washington DC area harbored antibiotic-resistant bacteria.  [expand] This study found salmonella isolates in 20% of the meat samples analyzed [/expand]

The majority of the drugs administered are identical or related to those administered to humans, which increases the concern for the development of antibiotic-resistance bacteria strains.

    It is incredibly important to take care of the environment, I really support it!

    I studied the issue of water resources and found out that current estimates showed that our planet contains a huge amount of water – about 1386000000 cubic kilometers (1.386 billion km3). However, 97.5% of this volume is salt water and only 2.5% is fresh water. Most of the fresh water (68.7%) is in the form of ice and permanent snow cover in the Antarctic, Arctic, and mountainous regions. Further, 29.9% exists as groundwater, and only 0.26% of the total freshwater on Earth is concentrated in lakes, reservoirs and river systems, where they are most easily available for our economic needs. But I think that this is the fact that people should be serious about ecology, and especially the younger generation of college and university students, they should be told about this even at school!
