AS THE ROMANS SAY, "RARA SUNT CARA". RARE IS VALUABLE. (CHINA)

The changes in diet occurring in China carry rippling effects around the world. What China’s hungry for makes a difference, said Janet Larsen of the Earth Policy Institute, adding that, “when a few people jump it may cause a ripple, but when a billion people jump, it’s a major shockwave.”

This week, we will be momentarily going back in time in China to compare eating habits in the past to today's eating habits.

Sorry, it might not be all that fancy...

Last week we focused on the consumption trends in USA, this week we are focusing on an even bigger area and an even bigger problem. China now eats twice as much meat as the United States. This is evident in the diagram below. Meat consumption in China is increasing for various reasons and we will be inspecting the main reasons for this trend in today's post. 

Meat consumption compared between China and U.S.

China in 1980's:

Meat was seen as a luxury; each Chinese ate just 13kg of meat, the equivalent to one tenth of a pig a year. On the other hand, beef was so rare it was nicknamed "Millionaire's meat". 

As China started to emerge from a state of poverty, meat consumption increased. As the Romans say, "Rara Sunt Cara", Rare is valuable. Since China's incomes were, and still are increasing many traditional Chinese foods are being switched to the 'luxury foods'. Instead of rice, individuals are replacing this with meats. Beginning in the 1980s, officials enacted measures to promote livestock production, including support for development of a feed-milling industry and subsidized imports of more productive animal breeds. Such incentives has led to incorrect information in the economy and incorrect incentives; individuals became more enthusiastic about livestock production and began to see it positively.

Dinner would probably look something like this in 1980's

China today:

Currently, China is a big player not only on the demand side, but the supply side too. “China produces and consumes about half of the pork in the world,” Schuele said." Consumption and demand of meat is increasing as low income families gradually climb the ladder up to become middle income families. The meals an average Chinese middle income family is eating now, would be a feast to their parents. 

Moreover, Meat consumption is doubling every 10 years." In all, the country now eats more than 60m tonnes of meat a year; equivalent to 240 million cows, or 600 million pigs, or 24 billion chickens. These facts suggest a very large scale problem that is arising not only in the respects of greenhouse gases emitted in the process but also feed needed for the livestock. Since meat consumption is increasing, it has led to individuals noticing this trend and moving towards setting up small farms. A shift in those with household and small farm productions to larger scale meat factories. This seems to be showing a cyclical trend, in which higher demands lead to higher supply and this reduces prices, such that demand can increase even more.

Benefits:

So far we have focused on the trends in meat production and consumption in China. Having read my previous posts, one can assume that the increasing trends are detrimental to the planet. It is true in some respects, but on a micro level, it has actually shown a big improvement to the Chinese people's lives.

In lifting 300 million people out of poverty over the past 30 years, China also saw an improvement in diets that made the country healthier. According to the World Food Programme, a six-year-old boy today in China is 6kg heavier and 6cm taller than his counterpart at the start of economic reforms in 1978.

Although it may be true that the health conditions of the people in China may have improved, this correlation may not be directly as a result of the consumption of meat. It could be argued that due to increasing incomes, families can now afford to buy more varieties of foods. In poorer areas of China, families may be eating the exact same foods at each meal; this means the nutrients absorbed would be very limited. By having higher incomes, more varied vegetables could be introduced into the Chinese diet instead of putting emphasis on the role of meat.

Beef:

Beef has not become as popular in China because cattle in feedlots gobble up about 7 pounds of grain for each pound of weight gain. For pigs, the feeding ratio is 3 to 1, and for chickens it is 2 to 1. With one fifth of the world's population and limited land and water supplies, China has had to rely heavily on the more-efficient forms of animal protein. 

This is good news for the environment since beef is the biggest contributor to global warming as discussed in previous posts. On the other hand, other meats have been a big hit in China instead.

Pork:

Over half of the world's pigs now live in China. By the end of the year, it is projected that there will be almost twice as many pigs in China as people in America. In the last few decades, China has developed the world's largest pork industry to feed a rising middle class. A quickly rising appetite for pork in China has fueled the sudden jump in production. In mid 1970s, an average Chinese citizen ate 8kg of pork a year. Now, each person eats about 39kg of pork a year. 

China has now overtaken American pork consumption

Poultry:

Poultry production never existed prior to 1978. Chicken flocks in China have grown rapidly. Since the raising of chickens are much simpler and easier than raising ruminants, China has been a big producer of Chickens. The demand and consumption of poultry is also growing.

Although some may perceive that consuming poultry is not as bad for the environment since chickens do not emit methane the way ruminants do, the main environmental concerns are derived from the chicken feed. According to earth-policy.org, more than 60% of the world soybean exports, nearly all from the United States, Brazil and Argentina, go to China. These crops are very often grown in highly unsustainable conditions; ways which involve deforestation which leads to a reduction of biodiversity. 

Sorry, you just can't win either way I'm afraid.

9 Reasons why Vegetarians Make Awesome Girlfriends

GET VEGUCATED

This week I came across a documentary which highlighted the journey of a few Americans changing their American diets to a vegan diet. Being able to see Americans go from one extreme to the other; being heavy meat eaters and transitioning to clean plant based palettes is actually very inspiring.

The journeys show how each person from varying backgrounds went through ups and downs through the transition phase and dictates the possible trip ups we may face which are all rather understandable.

Take a look at the documentary to see how they change their diets and the explanations on environmental impacts but also, whether livestock production is as humane as we imagine!


If you only want to see the environmental impact explanation only, skip to 35.00mins! 

Happy watching!

Perhaps even UCL should get vegucated!!

These are some posters I spotted around UCL...

Although the information may be true, and of course we should all think twice before using up resources, but I have never EVER come across a poster in canteens to say 'Did you know of the impacts of choosing this meal of steak and chips?'

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!

Happy Meatless Monday! Tune in next Monday for a new FUN MYSTERY POST! Look forward to it!

GLOBAL WARMING CONCLUSIONS

After our discussion on the main contributors to global warming and environmental change, here is a wrap up of what we can possibly conclude from research and data.

Possible conclusions and predictions:

Overall, the increasing global demand for meat is most likely to negative effect the environment. 

1) Demand

Since the demand for meat is increasing (perhaps even exponentially) through developing countries, increase in incomes, population growth and urbanisation, the amount of livestock would probably increase since suppliers and those in the industry will see this as a profitable opportunity. Predicted by WHO, annual meat production is projected to increase from 218 million tonnes in 1997 - 1999 to 376 million tonnes by 2030.

2) Supply - Large scale production

Since more space will be needed for large scale production of meat, whether it is areas for the livestock to live and graze, but also slaughter houses. This means there are implications for these processes to become more closely located to urban centres. By being in close proximity with urban centres, a range of environmental and health risks will potentially exist, such as those mentioned before. Land and water requirements would lead to a degradation and depletion of resources. 

3) Urbanisation and development

Due to urbanisation, development in certain countries and technological improvements, transportation of meats are becoming more efficient. This has also spurred on a 'taste for meat'  This is evident in city dwellers who have a varied diet rich in animal proteins and fats, and characterized by higher consumption of meat, poultry, milk and other dairy products. This can be seen in the table below. There is a significant increase in meat consumption in Brazil and China. However it can be seen that the consumption in North America and other developed countries remain at a much higher level. 

Per capita consumption of livestock products

Region	Meat (kg per year)			Milk (kg per year)
	1964 - 1966	1997 - 1999	2030	1964 - 1966	1997 - 1999	2030
World	24.2	36.4	45.3	73.9	78.1	89.5
Developing countries	10.2	25.5	36.7	28.0	44.6	65.8
Near East and North Africa	11.9	21.2	35.0	68.6	72.3	89.9
Sub-Saharan Africaa	9.9	9.4	13.4	28.5	29.1	33.8
Latin America and the Caribbean	31.7	53.8	76.6	80.1	110.2	139.8
East Asia	8.7	37.7	58.5	3.6	10.0	17.8
South Asia	3.9	5.3	11.7	37.0	67.5	106.9
Industrialized countries	61.5	88.2	100.1	185.5	212.2	221.0
Transition countries	42.5	46.2	60.7	156.6	159.1	178.7

As shown, the global demand is increasing in general, but is especially prominent in the BRICS, the five main emerging national economies which represent the trend in growing meat demand within countries with increasing income and wealth. 

The flip side

Although meat consumption can be seen to be increasing in the BRICS, it has actually stagnated in the U.S. according to Business Insider. Perhaps it can be argued that more educated and industrialised the countries are, despite having seen a rapid increase in meat production since 1950s, it has recently stagnated. For example, in the U.S., consumption has dropped by 9% from 2007 to 2012. This could be due to low-meat trends, and more educated consumers who are more concerned with the source of the meats. Furthermore, due to the horse meat scandal which was marketed as beef in early 2013, consumers have become more cautious about what they are eating and the credibility of food labels.

Conclusions:

Perhaps the key conclusion here, is trying to educate consumers on the health risks, environmental risks and the reality of how livestock are treated which can then reduce demand for meat. Although policy measures can be put into place to help reduce the harmful effects, consumers also play a big part too.

According to www.virtualcentre.org, the best way to improve efficiency is to price natural resources with the externalities considered. This is because when public resources are underpriced, it causes overexploitation. As a result, such a pricing strategy is able to allow individuals who use the resources to be mindful of the real cost of its usage.

Efforts here can lead to large and multiple payoffs.

Possible solutions:

To reduce greenhouse gases that have been and will be emitted as a result of the livestock sector, a few solutions have been raised in 'Livestock's Long Shadow':

• Restore historical losses through conservation tillage
• Agroforestry (a more sustainable land use system in which trees or shrubs are grown around or among crops to promote more healthy, sustainable and productive land usage)
• Restoration of desertified pastures
• Methane emissions: improved diets to reduce enteric fermentation, improved manure management, biogas
• Nitrogen emissions: improved diets and manure management
• Use tradable rights for natural resources
• Remove damaging subsidies and alter the price for the resources in order to take into account the environmental externalities

How can we move on from here?

WATER'S YOUR PROBLEM?

A new report from FAO says livestock production contributes to the world's most pressing environmental problems, including global warming, land degradation, air and water pollution, and loss of biodiversity.

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

It is estimated that it takes 2,500 gallons of water to produce one pound of meat (about 5-8 servings of meat). For comparison it takes only 25 gallons of water to produce one pound of wheat (enough to make one loaf of whole wheat bread). Irrigation for feed crops contributes significantly to this overuse of water. Soy and corn are heavily irrigated crops in the U.S. and are used extensively for livestock feed. Most of the grain produced in this country is for livestock production.

Since a large proportion of the grain produced is feed for livestock shows precisely how the grains could be instead, directly created into food for humans. Thus the extra step of feeding livestock (along with the negative environmental impacts associated) could be skipped. 

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!

MAYBE WE'RE WRONG? NITROUS OXIDE DEBATE

Nitrous oxide is about 300 times more potent as a global warming gas than carbon dioxide. According to the U.N., the meat, egg, and dairy industries account for a staggering 65 percent of worldwide nitrous oxide emissions.

Nitrous oxide has been pinpointed as third most important contributor to global warming. Extensive research shows that large quantities of nitrous oxide is emitted as a result of livestock. This is evident in numerous scientific literature such as in the Soil Biology and Biochemistry journal, page 597, 'Nitrous Oxide Emissions from soils due to inputs of nitrogen from excreta returned by livestock on grazed grassland in the UK.'

There are also very detailed explanations on the N₂O emission calculations for each component of livestock production systems, i.e. animal houses, manure stores, following application of manures to land and during grazing in 'Atmospheric Environment', under 'A UK inventory of nitrous oxide emissions from farmed livestock'. If you are interested in the statistics related to each of these stages in the livestock production, head over HERE!

Naturally, nitrous oxide is emitted. This can be seen in the nitrogen cycle as shown below:

The actual nitrous oxide is emitted through feed production and the management of the manure. The former occurs due to the nitrogen based fertilisers used in the soil which leads to nitrous oxide releasing in the atmosphere.

According to new research however, Professor Klaus Butterbach-Bahl from the Atmospheric Environmental Research Division of the KIT Institute of Meteorology and Climate Research (IMK-IFU) in Garmisch-Partenkirchen said, 'this was a big error'.

Founded by scientists from the Atmospheric Environmental Research Division of the KIT Institute of Meteorology and Climate Research, studies in China show that livestock breeding does not lead to an increase in nitrous oxide. “In fact, areas not used for livestock breeding emit much larger amounts of nitrous oxide over the year.” 

The website also states that nitrous oxide emissions have been overestimated by 72%.

Supported by the 'Nature study' shows evidence pointing towards the link between grazing and the reduction in nitrous oxide emissions in some areas. 

Despite this opposing view on whether livestock is the root cause of nitrous oxide emissions or not, increasing nitrous oxide in the atmosphere is still a fact, and nitrous oxide is being emitted due to human-related agricultural factors.

Furthermore, Authors of the paper, published in Nature, say the research does not mean that producing livestock to eat is good for the environment in all countries. However in certain circumstances, it can be better for global warming to let animals graze on grassland.

What do you think?

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?

"You could exchange your “regular” car for a hybrid Toyota Prius and, by doing so, prevent about 1 ton of carbon dioxide from entering the atmosphere each year, but according to the University of Chicago, being vegan is more effective in the fight against global warming; a vegan is responsible for the release of approximately 1.5 fewer tons of carbon dioxide into the atmosphere each year than is a meat-eater."

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?

"Producing one calorie from animal protein requires 11 times as much fossil fuel input—releasing 11 times as much carbon dioxide—as does producing a calorie from plant protein. Feeding massive amounts of grain and water to farmed animals and then killing them and processing, transporting, and storing their flesh is extremely energy-intensive"

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):

Food group	Food	CO2-Emissions (in g per kg food)
Meat and sausages	Beef	13'300
	Raw sausages	8'000
	Ham (pork)	4'800
	Poeltry	3'500
	Pork	3'250
Milk- and dairy products	Butter	23'800
	Hard cheese	8'500
	Cream	7'600
	Eggs	1'950
	Quark (curd)	1'950
	Farmer cheese	1'950
	Margarine	1'350
	Yogurt	1'250
	Milk	950
Fruits	Apples	550
	Strawberries	300
Baked goods	Brown bread	750
	White bread	650

We can also break this down by looking at carbon dioxide emissions per calorie:

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.
