TO THE TRUTH I NEVER KNEW, NOW I CAN MAKE IT WITHOUT YOU

HAPPY MONDAY!



Firstly, thank you so much for taking this journey with me to find out more about livestock production and the impacts we are making through unconscious everyday decisions. I enjoyed writing this blog much more than I expected, and I am so thankful for having the chance to give it a go. Whilst you may have learnt a lot from this blog, it has been a learning curve for me too, and I've constantly been growing as I learn more about the information I'm digging out.

Although this is the end of my Geography assessment, but I would really appreciate it if you left me any comments with your thoughts and if you have any great website links for me to learn even more! I would LOVE to read it!

So, into the nitty gritty stuff, I'm going to just briefly outline the main solutions to the meat problem.

1. Government

The government needs to find ways to discourage major producers from rearing livestock near city areas through either zoning, taxes or incentives. For example, in Thailand, there are high taxes on poultry production within a 100km radius of Bangkok. This has been effective in reducing poultry production near Bangkok.

2. Waste management

Use manure as a fertiliser rather than polluting waters.

3. You

Become as vegetarian/vegan as you possibly can. “Eat meat, but less often — make it special,” Mark Sutton, lead author of a U.N. Environment Programme 2013 study on meat consumption, said. “Portion size is key. Many portions are too big, more than you want to eat. Think about a change of culture that says, ‘I like the taste, but I don’t need so much of it.’”

I want to leave you with something very important that I have learnt through this journey with you.

Understand that you, as a consumer, have a level of social responsibility. What you spend your money on is the key to change (by altering demand, it can alter supply).

Mooney says "If they are informed that they do have choices to help build a  more sustainable and equitable world, they can make better choices."

Finally, a quick reminder of the serious extent of animals slaughtered just for the plate on your table.



You've been such amazing readers every Monday, I really hope you're able to join my Meatless Mondays, whether I have a new post every Monday or not! To make me very happy, please sign the Meatless Monday pledge!!

COUNTRIES COMPARED

Today we will be focusing on the worldwide meat production and consumption.


If you were interested in the previous post (the table with a breakdown of meat and milk consumption per country/region) here is a more comprehensive review of the meat production and consumption for ya! 

For those who prefer a more visual breakdown;


1) Worldwide Meat Production


The production of meats in USA and Europe is increasing, however this is equally matched by increasing prices due to the high costs associated to livestock production. However, pigs and poultry are doing well in the market since both species do not need a lot of feed and can be kept in confined spaces.



2) Top Ten International Meat Industry:


Four out of the ten are based in the US; Cargill, Smithfield Foods, Tyson Foods and Hormel Foods. Three are located in Brazil; JBS, BRF and Marfrig. The rest are in Denmark, Netherlands and Japan.



Looking more carefully at the estimated meat consumption and the forecast, it seems that the increasing meat trend may not be so applicable to all countries.


3) Demand in the rich world



This may actually reflect on the fact that the 'richer' may be positively correlated to being more 'educated' and thus may be seeing a reduction in meat consumption. Despite this, only in less than half of the cases shown in the diagram above, shows a decline in meat consumption. Even so, the decline is very minimal and would be outweighed by the increases in meat demand. For example, by 2020, China's poultry production will increase by 37%, Brazil's will increase 28% and U.S. will increase by 16%. Nevertheless, the fact that there are forecasts for some countries lowering their meat demand is a good sign and goes to show that perhaps we can turn the tables.




Having identified and compared the different meat consumption patterns of different countries, we will proceed to look more carefully into specific regions in future posts!

BIODIVERSITY


So, what is habitat destruction?



THIS IS HABITAT DESTRUCTION.

Habitat destruction is altering the environment in which organisms live such that the conditions of the environment is no longer fit for their requirements. This may lead to them moving to other more suitable areas that suit their needs to survive, or could ultimately lead to extinction. Habitat destruction is currently ranked the highest in causing animal extinction worldwide.

Although the above quote suggests that 23 out of 35 of the global hot spots for biodiversity is affected by livestock production, the website does not then go on to explain how the country is classified as 'affected' and does not include an explanation as to how it is measured. Nonetheless, it is a very significant figure and should not be ignored.


If you're interested, hop onto the website: http://www.iucnredlist.org/ and refine your search by changing the categories (to find out about livestock production affects, choose the option 'Threats' and then choose 'Agriculture').


Possible solutions:

Wild areas need to be protected as much as possible, either through buffer zones which can protect a conservation area or civil or criminal penalties. An example of this is the Environment Protection and Biodiversity Conservation Act 1999 written by the Australian Government under the Department of the Environment. They have enforcement mechanisms for suspected non-compliances which include such penalties to deter individuals or corporations from harming biodiversity. 

Additionally, more incentives should be created by the government, for example through subsidies which can help the livestock producers to be more willing to conserve such areas and protect biodiversity.

WATER'S YOUR PROBLEM?

This week I was able to cosy up to read 'Livestock's Long Shadow: Environmental Issues and Options'; a United Nations report released by the Food and Agriculture Organisation of the United Nations. So far we have focused on the issues surrounding greenhouse gas emissions as a result of meat production and the responsibility of the consumers in contributing to the meat consumption and trend. 

Having read the report, it has highlighted a few important things on the correlation between the livestock sector and global environmental change. I will be writing about other vital environmental problems related to meat production in later posts, and will be looking at possible solutions outlined by the report. These solutions are mainly focused on the technical and political levels in reducing the environmental harm that has and will be caused as a result of meat production.



Today we will touch upon water use and the solutions from a political level to cover how global environmental change can be reduced.



The world is slowly opening their eyes to more issues from freshwater shortage, scarcity and depletion. 64% of the world'spopulation is expected to live in water-stressed basins by 2025. Thelivestock sector accounts for up to 8% of the global human water use (mainly through irrigation for feedcrops).

i) Water Overuse



ii) Water Contamination and Pollution:
The main contributors to water pollution include animal waste, antibiotics and hormones, chemicals from tanneries, fertilisers and pesticides used in feed production and sediments from eroded pastures.


Livestock operations overuse water and may lead to water contamination. The large amount of waste pro­duced on factory farms exceeds the capacity of nearby cropland to absorb it. As a result, manure goes from being a valuable agricultural resource to what is essentially toxic waste. Nitrates, heavy metals, and antibiotics present in manure can seep into groundwater and pollute surface water. Furthermore, when manure lagoons leak or burst, again, nitrates become exposed to the water we drink. The Environmental Protection Agency (EPA) has warned that E. Coli, salmonella, and Giardia found in dairy cattle waste can contaminate drinking water and cause acute gastroenteritis, fever, kidney failure, and even death. It not only affects humans,  but also the sea animals too. There have been numerous instances where this has killed off thousands of fish. No wonder people are saying fish are becoming more scarce!


Water pollution leads to fish death


Water pollution can lead to several undesired results, it contributes to eutrophication; a process where water bodies receive excess nutrients that stimulate excessive plant growth. It could also lead to "dead" zones/hypoxia in coastal areas, this is causes regions of water that lack oxygen necessary to support animal life and as a consequence, become a cause for extinction. Not only does water pollution affect animal life, but also degrades coral reefs. Apart from affecting animals and plants, water pollution causes human health problems due to reusing water in the water cycle and can cause an emergence of antibiotic resistance.

Livestock also affects the replenishment of freshwater by compacting soil, reducing infiltration, degrading the banks of watercourses, drying up floodplains and lowering water tables.


Please save us...

How can water pollution be avoided?

The best way to mitigate water pollution would be to better manage animal waste. This is important as animal waste can cause excess nutrients and pathogens to enter and harm water quality; instead the waste could be reused as a natural fertiliser for crops. Furthermore, better diets for the livestock can improve nutrient absorption.
Possible solutions:

Since water pollution is a problem for not only plants and animals, but humans too, it means humans should put more care into reducing water pollution where possible. I have broken down some possible solutions in improving efficiency of water  use. The first solution is to improve the efficiency of irrigation systems such that there are no unnecessary water losses.

The fact that water is often free and easily available causes the 'free rider effect' used in Economics, where a resource may be over exploited since it is priced at 0. To avoid this, water should be priced at a level that takes the externality into account. Similarly, there should be regulatory quantitative frameworks to limit usage. 

To reduce concentrated areas of livestock rearing especially near cities, zoning regulations and taxes can help to control this. As a result, the harmful effects on human health can be restricted too. 

Happy Meatless Monday!

HOW TO TRAIN A RUMINANT

Methane (CH4)  is emitted naturally and through human sources. Natural sources make up 36% of all Methane emissions and this includes wetlands, turmite and the oceans. The remainder is emitted via human activities; this includes landfills, livestock farming and use of fossil fuels. Methane can be removed from the atmosphere through natural processes in soil. But for a long time now human activities have been creating methane emissions much more rapidly than the Earth can remove them, increasing global methane levels.


Methane's lifetime in the atmosphere is shorter than carbon dioxide, but "animals produce 37 percent of methane, which has more than 20 times the global warming potential of carbon dioxide."  Additionally, as shown in the pie chart below, the human sources of methane are predominantly due to livestock farming and fossil fuel production. This is indicative of the importance and detrimental impact of methane emissions.




So how exactly do livestock emit methane?

If you want the short answer to how animals emit methane, look no further, we do it all the time: burps, farts and breathing.


No kidding.



And the long answer goes like this.

Cows come under a the mammal group called ruminants which acquire nutrients from plant based products. They have four stomachs; where the food is digested. The stomach is filled with bacteria, and when food is digested, methane is also manufactured in the process. 

(If only I had four stomachs...)





Furthermore, in the animal manure storage tanks, methane is produced. Imagine the extent of methane produced;

How to train a ruminant:

Give your cow some garlic to reduce methane emissions, apparently...

TO REDUCE CO2 EMISSIONS, PLEASE HOLD YOUR BREATH


Joke.


I sincerely hope it wasn't too late to say the title was a joke...


A lot of us (including me) are clouded by the idea that by recycling every last bit of recyclable material, not driving at all, using alternative energy sources and growing plants in your back garden can do a whole lot in reducing carbon dioxide, thus keeping climate change to a minimum. I mean, every time I scolded my sister for leaving the light on without needing it made me feel like a saint. (Why so serious?) My parents even considered changing to a hybrid car!


Have you changed to a hybrid car?




Did you know?
Well, we are not entirely wrong in thinking this can help us curb climate change. Although these measures are contributing to the improvement of the lives of impending generations, it is worth looking into the bigger picture and the major driver of the actual problem.

Allow me some time to break down precisely why our world is a bombshell that is about to explode.
What is global warming?
Global warming is caused by the mixture of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These are the three main causes of climate change. Not enough of us realise that animal agriculture is one of the largest contributor to global warming through the immense carbon dioxide, methane and nitrous oxide emissions.

How does animal agriculture lead to increases in CO2?


Below is a break down of the steps in animal agriculture which require high amounts of energy and thus releases a lot of CO2 (Taken from Get Vegucated Documentary):




FUN FACT:


Animal manure releases CO2 as well.

If you're into tables and figures, there is a cohesive break down of CO2 emitted in grams per kilograms of food from its production, according to timeforchange.org.



CO2-Emissions (in g CO2e per kg food):

We can also break this down by looking at carbon dioxide emissions per calorie:
http://shrinkthatfootprint.com/food-carbon-footprint-diet

As we can see, in both instances, the carbon dioxide emissions of foods differ according to its process of production, but it is also very clear that despite different measures; meat and particularly beef has the biggest impact on the environment due to its highest carbon dioxide emissions. 

Thus perhaps we should all think twice about what we consume and the amount we consume, as much as how much energy we use/waste!

P.S. If you live in the US, please don't forget to participate in Food Day on 24th of this month! http://www.foodday.org/about

P.S.S. Food Day inspires Americans to change their diets and our food policies. Every October 24, thousands of events all around the country bring Americans together to celebrate and enjoy real food and to push for improved food policies.

MEET THE MEAT CULTURE!

In the developing world, people eat about 30 kilograms of meat a year. But consumers in the industrial world eat more than 80 kilograms per person each year. - World Watch Institute


Why is the livestock sector so important?

It's easy to just follow the crowd. It's easy to blame the society and its norms, whether they're putting pressure on us, or restricting us. 

How did the meat culture start?

When human beings moved out of the equatorial areas where plant foods were unavailable year round, humans began to hunt for their food. This meant that meat consumption was necessary for survival. This was mainly in the periods of severe droughts or in seasons where crops cannot grow.

Eventually, the consumption of meat became almost part of the culture in those countries. As a result, meat consumption has integrated into these people's lives and so humans began to eat it anyway; because it was cultural and had a deeper meaning. (Taken from Get Vegucated Documentary)

 
However, now we can have access to plant food year round due to improved technology to allow imports, why do we continue to eat meat unnecessarily?


 

The fact is, when something is 'trendy', that thing becomes unnecessarily popular and essentially desirable; often without reason.

As our fellow friends, the Economists would say, a trend is a reason for an increase in demand for a product. Consequently leading to an increase in supply for the product, shifting the equilibrium, and thus increasing quantity (and sometimes the price).

Remember our dear burger?

This worldwide consumer trend, (in the Google Trends screenshot in previous post) has contributed to the overall increase in demand for meat. Of course, there are other underlying reasons for higher meat demand over the years too, such as higher incomes and more efficient transportation methods.

As shown below, the world meat production has been increasing at a very high rate;

 





Global meat production increased by 2.6 percent in 2010 to 290.6 million tons, an increase from the 0.8 percent growth rate of 2009. Even with this minimal increase, however, worldwide meat production has tripled since the 1970s. The increase continutes the steady growth of the past decade. Since 2000, global meat production has risen by 20 percent.
But why are humans becoming more and more carnivorous?

 

1) Countries becoming wealthier
 
 The consumption of meat and the level of income are positively correlated. Meat and dairy are replacing staple foods due to higher incomes and wealth.

 
 
World Watch Institute, written in 'Meat Production Continues to Rise',
 
"Experts predict that by 2050 nearly twice as much meat will be produced as today, for a prejected total of more than 465 million tons. For more than a decade, the strongest increases in production have been in the developed world in 1995 more meat and dairy products were produced in developing than in industrial countries for the first time, and this trend has continues ever since. In fact in 2007, at least 60 percent of meat was produced in developing nations."

 
2) Population growth
 
With the population growing exponentially, humans need to find more resources to ensure survival. 
 
 
3) Urbanisation
 

"Urbanisation stimulates improvements in infrastructure, including cold chains, which permit trade in perishable goods."

4) Developing countries

Due to the declining prices in developing countries, the average family is more willing and able to have meat in their diets and thus meat consumption has increased. Furthermore, the idea that meat is a luxury food product is causing the food palette to change from cheaper foods (like vegetables) to meat. 


Just because of natural human behaviour; to have the desire to jump on the bandwagon, and want to be seen as desirable by our peers, meat production has become a growing industry.

In effect, its digging our own graves and the graves of our future.


IF WE'RE NOT DEMANDING IT... THERE IS NO NEED TO PRODUCE IT.

AN OPEN LETTER TO THE "FOODIES"

Dear "Foodies",

We met at a fast food restaurant, a friend's house, in a convenience store, wherever, you chose me, out of an array of colourful options.

You took pride in the 100+ likes you gained on Instagram from photos with me. 

You devoured every moment with me, because I was there when you were lonely, and I was there when you had a great night with your best friends. I've seen you in all your glory, celebrations for passing your exams, crying over the friend who betrayed you, and being sick on your bathroom floor after a night out. 

So it began like that. I set out to lure you in, and now you're determined for more.

Ultimately, I'm so glad I'm the latest trend. Because quite frankly, people used to neglect us quite a bit.


A sincere thank you, for choosing me.

I look foward to seeing you very soon,
Your favourite,

MOUTHWATERING JUICY BURGER (with extra mature cheddar cheese, gherkins, extra layer of meat, jalapeno, mushrooms, pickles, tomato sauce, mayonnaise, mustard, lettuce, tomatoes, caramelised onions, chilli, spinach, bacon, fried egg, and more cheese, with my dear friend, fries and the handful of salad that no one seems to touch.)

---------------------

Having been taken by storm with the burger boom, with over 3million posts with the hashtag #burger on Instagram up to date, humans are craving every type of burger out there in every corner of the globe.  This is evident by just searching the term 'burger' in Google Trends, which portrays the ever increasing interest in burgers and its popularity in a variety of countries.


http://www.google.co.uk/trends/explore#q=burger&cmpt=q


Global production of meat is forecasted to more than double from 229 million tonnes in 1999/01 to 465 million tonnes in 2050. The environmental impact per unit of livestock production must be cut by half, just to avoid increasing the level of damage beyond its present level.


With entrepreneurs taking this opportunity to exploit this trend, crazy burger ideas have been brought to the market, such as the 'Glamburger' costing an arm and a leg (in other words, £1,100) in Chelsea, in exchange for the most extravagant ingredients which include black truffle, Himalayan salt and a gold leaf.



Ultimately, "burgers are culinary survivors: They can adapt no matter where mainstream tastes flow." The burger trend can evolve in ways to ensure its survival with new trendy ingredients.


After this introduction, you may be seduced by the idea of reaching for a big juicy burger whilst you finish reading this post, perhaps its worth stopping for a minute to realise the real value of what you're eating.


Yes, we've been there, taught that. Burgers (and pizza, chips, soda bla bla bla) are bad for your health, don't eat them. Well, we all thought we're old enough to deal with what we put into our bodies, and lets face it, all this controversy is only applicable to small kids who can't control themselves.


Wrong.


In the traditional sense, yes, burgers are bad for you. Too much fat, sodium and whatnot.

But on a macro level, eating burgers (and meat in general for that matter) is harming the earth. How so, you ask.





A report from the Food and Agriculture Organisation of the United Nations (FAO) cited livestock production as "one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global." 

"The environmental damage by the livestock sector goes far beyond the sector; it also goes beyond agriculture."

DID YOU KNOW? 



When put into perspective, those juicy addictive burgers are no longer just a health risk but a risk to the world. 


The consumption of meat is a huge interest to me personally, as I have always lived under the impression that a bit of meat is good for the body and have never thought twice about how it could be harmful to the environment. Being a 'good human' (if I should say so myself), recycling where possible, walking instead of driving a car and even keeping food waste as compost made me think I was putting in more than my two cents, surely! After reading more on meat consumption, I have become intrigued in the scientific journals that point to the harmful effects on the planet.


Throughout this blog, I will be providing more information regarding meat consumption, its impacts and potential effects on global warming and other environmental impacts as a consequence of meat production.
