Farmers Are Being Pushed to Increase in Size Or Get Out! How to NOT Be One of Them
Farmers Are Being Pushed to Increase in Size Or Get Out! How to NOT Be One of Them
It doesn’t matter what size it is, your farm is an ever increasing asset, even more so if you can provide chemical free, clean food.
Australian conventional food prices are forecast to quadruple in price over the next five years. The reason is Asia. We are in the middle of a global revolution in the way we think, eat and live.
This week I received this news from Craig Sobey who has recently toured China with representatives from five city councils, Austrade and Regional Development Victoria and reports that there is a real opportunity for all to take a significant market share in this period.
Basically, if it is Australian and premium quality there is a ready market. Australia is seen as a source of safe food regardless of whether it is organic or conventional. At this stage price does not appear in the conversation, just consistent supply and traceability. The interest in all products represented included convenience food packages (pre-cooked), meats, dairy, wines etc.
Did you know:
- This co-op now owns China’s fifth biggest supermarket chain with over 500,000 stores.
- There is a farmer’s co-op representative with over five million members?
- 6,000 of them over 30,000 sq metres. The supermarket turned over 18 billion dollars in 2007 with revenues growing by 150 % per annum on average.
- They have offered an entire Australian Pavilion for Aussie produce including organics in their premiere stores in Beijing and Shanghai. Organic Wines were the big attraction.,
- China creates 80,000 millionaires each year.
- There are over 350 million middle class and a niche market of super wealthy Chinese? (Craig told me that French wine is selling as much as $600 a bottle and even one watermelon cost $40!).
However there is real interest in China for organics (which they refer to as Green Food) and particularly food safety/ traceability which is the paramount concern for all serious buyers they met. A new Australian wide network (not for profit) company is being formed for all sections of the organic market. This is so that a pool of members can tackle the export markets together. Its goal is to give you an export premium to help make membership very appealing.
The time is ripe for all growers to stop and think about the future of their farming. What choice will you make? Your future will depend on it. Even if all of Australia’s certified organic farmers, processors etc. were to unite they could not supply the market in China alone and therefore there is untapped potential over the next ten to twenty years to be further developed.

Against Genetically Modified Foods
Against Genetically Modified Foods
Genetically modified (GM) foods are not being found to be safe for humans, or for the environment. There are a number of reasons why there a growing number of people are against GM foods. Are Genetically Modified Foods Safe? The reason to resist the growth of GM food in our diet is that it has a negative impact on our environment; plants and animals grown organically are not distorting their genetic makeup.
And in the rush to accelerate the production of genetically modified foods, scientists are short cutting testing methods. Recently, the United States Tufts University, School of Medicine was involved in testing the effects of genetically modified rice directly on children (by-passing the usual practice of testing on animals). This direct testing on children created controversy and a formal letter of protest from 22 international scientists to the University; the protest letter has been made public through various social media.
The letter protested the use of children as a breach of medical ethics code since children cannot legally give their consent (since it is not deemed to be informed consent) to participate in experiments. As Professor David Schubert, Salk Institute of Biological Studies said, “…it is completely immoral to feed this rice to children without proper safety testing … [i]t’s like putting a new drug on the market with no toxicology or safety trials”.
In defense of their position, the Golden Rice Organization issued a press release that states they “…us[ed] the correct Chinese and US government approved processes, the trials in China went ahead last year with the formal approval of their parents and the understanding of the children”. How do children understand the impact of genetically modified food on themselves or the environment? It’s a complex subject that many adults have a hard time understanding. Also, how can anyone (parents, children, or testing scientists) understand what the long term effects of genetically modified “golden rice” are on the human body without prior study or testing?
More importantly, will the overall risks of genetically modified foods over time out weigh the alleged benefits? Farmers have cross-bred plants and animals for hundreds of years to improve their products. Improvements to size, produce yield, taste, hardiness have been achieved through relatively natural means and within nature’s own boundaries; different species were not bred together.
With the discovery of DNA and a method of gene extraction, the concept of genetic modification was born. The intent of genetic modification is to create food that grows quickly, yields much, is resistant to pests, to disease, and to other natural events. However a number of scientists respond that the benefits are not worth the risks; genetically modified foods often become resistant to herbicides and pesticides requiring ever increasing amounts. There is the suspicion (still unproven) that pollinating bees have been affected by the increasing use of these chemicals and that both pollinator and predator species have been affected by the genetically modified crops (also known as transgenic crops) through habitat destruction and use of dangerous herbicides and pesticides.
Since the introduction of genetically modified foods, some scientists are reporting that food-related illness has increased. The only published human feeding study confirmed that genetic material in genetically modified soy transferred into the DNA of intestinal bacteria and continued to function. What long term impact will these foods have on the population and the environment? There are many more potential risks in the development of genetically modified foods. Animals that were fed genetically modified feed appeared to suffer from increases in fetal death, low birth weight, sterility, and more. The concern is that human reproductive failure and sterility or infertility will be long term consequences to using GM foods.
In the US, the Department of Agriculture reports that cotton and corn crops have been genetically modified to produce their own Bt toxins since 1996. Bt modified crops are insecticidal crystal proteins and are considered effective against crop-damaging caterpillars. The toxins are considered important for pest control and since resistance to herbicides and pesticides is growing, the sentiment is that these genetically engineered Bt toxins will help to protect the crops. The issue with the GM Bt toxins is that they are considered serious allergens; ever wonder why so many more children and adults are exhibiting allergic reactions than ever before?
The problem with genetically modified foods is that there is also a reaction for the action; unfortunately, globally, in our rush to grow food supplies, we have not taken the time to properly test and research the long term impacts and effects of genetically modified foods. It is easy to be against GM foods - our planet is at risk.

Go Green – Get Rid of Junk Mail
Go Green – Get Rid of Junk Mail
Four million tons of junk mail is sent every year…at least half of which is never even opened. You probably are aware that your name, address, and spending habits are regularly being traded and sold on the open market. By investing half an hour now, you can rid yourself of most of the junk mail for up to five years…and save a few trees while you’re doing it.
So here are a few tips that you can work on to lessen the load of junk you get every day:
- Product warranty cards do not register your product…that was done when you purchased it. They are used to fin out about your interests and your income for the sole purpose of junk mail.
- When ordering something on the phone, tell them specifically to not give your name and address to other companies for any reason.
- Any time you donate money or order a product or service by mail, write on it in large letters, telling them not to sell your name and address.
- When the junk come by first class mail, cross out the address and bar code, circle the first class postage and write “refused: return to sender”.
- Your credit card companies are the worst offenders and probably sell your name and address more than anyone else. Stopping them is easy; you just need your address and social security number.

You Should Know Before You Shop Green
You Should Know Before You Shop Green
Going green always starts with good intentions, but the massive amount of green terms can sometimes be overwhelming. Here’s some of the common green terms you’ll hear and what they mean.
Organic
The term organic can often be used very broadly, but typically refers to products that have only organic components, produced without pesticides, herbicides, insecticides, or fertilizers or other harmful chemicals.
Look for: USDA Certified Organic
Sustainable
Products or materials that are described as being sustainable contain materials that do not deplete the Earth of its resources and is easily replenished. There are many common types of materials that are considered sustainable:
Bamboo - Bamboo is a fast-growing and renewable resource that can be used to make fabrics, flooring, furniture and other products.
Jute – Jute is a long and shiny vegetable plant fiber that can be woven into a strong thread or twine. It is commonly used to create cloth or used within carpets, and rugs.
Hemp – Hemp is a fast-growing plant that is most commonly used for its strong fibers to create cloth used in bags and clothing. It can grow organically and also be used to create oils for cosmetic products as well as be used in food.
Sustainable Wool – There are many types of sustainable animal wools such as alpaca fibers or merino wool that can be used to create strong fibers commonly used in clothing.
Energy-Efficient
Products that are energy-efficient are design to consume less energy when operating without sacrificing performance, reducing long-term environmental and cost impacts. Energy-efficient products can range from appliances to light bulbs as well as contain different levels of efficiency.
Look for: Energy Star Qualified, EPEAT Rated
Post-Consumer Recycled
Once a product has completely served its purpose, what remains are post-consumer materials that would otherwise be disposed as waste but are instead recycled. This would include products such as old packaging, glass bottles, aluminum cans, and plastics. When you recycle from your home these products become post-consumer recycled.
How is this different vs recycled? Regular recycled materials can contain a combination of materials, often coming a scraps or other by-products as a result of manufacturing. This could include both pre-consumer and post-consumer waste.
Recyclable
A recyclable product means that it can be recycled and be used to create future products. Polypropylene #5 is a common plastic to look for in products which is one of the most easily recyclable plastics.
Look for: Polypropylene #5
Reusable
Reusable products mean that a product can be used multiple times before the product is discarded or recycled. Some common reusable products are shopping bags, water bottles and tableware.
Fair Trade
Fair Trade is a social movement that promotes certain standards of sustainability practices and empowering producers in developing nations. Fair trade supports fair prices, fair labor conditions, community development and environmental sustainability.
Volatile Organic Compounds (VOCs)
VOCs are organic chemical compounds that have high vapor pressure and easily evaporate at room temperature. VOCs can be released from many household items such as paints, flooring, upholstery, and cleaners. These VOCs are not only air pollutants but have also been known to cause health effects as well.
Look for: Low-VOC, Zero-VOC
Bisphenol A (BPA)
BPA is an organic compound that is used in the creation of many plastics and resins. Most commonly you will find BPA used polycarbonate bottles. While there is some controversy about the effects of BPA, some research has raised serious health concerns about the usage of BPA.
Look for: BPA-free
Biodegradable
Biodegradable means that a substance can be naturally decomposed by biological processes. If a product is biodegradable, this means that it can be disposed of with no negative environmental impacts.
Solar-Powered
Solar powered products are powered using energy from the sun. Solar power can be used in a range of products from small household gadgets to entire home heating systems.

Save the Plastic Bag or Ban the Plastic Bag?
Save the Plastic Bag or Ban the Plastic Bag?
As part of the conservation and environmental movement worldwide there are several campaigns aimed at banning the plastic bag. These fit in perfectly with going green at home and with our longer term life styles.
A quick search on the web will take you to the San Francisco Bay Area, “Bay vs Bag”, to the Daily Mail’s (UK) “Banish the Bags” as well as similar situations in Canada, Holland, China, elsewhere in the US and even Zanzibar.
A lot of the focus is based on the damage done to wild life, including sea mammals and birds; the effects on waste and the average number of bags used per person in different countries. In one of the lists I saw, Singapore was topping the list at 625 bags.
One of the targets is to reduce by 10% the yearly consumption of these bags.
On the other hand there are also “Save the Plastic Bag” campaigns, with the plastic industry behind it. Their main focus is highlighting what they call misinformation. Their points are based on “exaggerations” on the damage done to wild life; errors in how plastic bags are made (from ethane gas that would otherwise be burnt and not petroleum); effects of co2 vs methane; potential job losses and so on.
On the banning side of the argument, there can be exaggerations as well as questionable scientific data – questionable as in anybody can question it, after all to have an argument you must always have at least two points of view.
From the “saving” the industry point of view, there can be many counter arguments to the data that is presented. And this is quite understandable, after all their industry could be hit very badly. (This just reminds me that all businesses have a life time curve that goes from birth, to growth, to maturity and finally to demise. The time scale can be as short as a year to as long as a hundred years or more, but the end result is that it is replaced by something else).
Some of the arguments are saying that nets and not plastic bags are causing marine life casualties, that paper bags are a worse alternative (side stepping the plastic bag issue) and basically attacking the “plastic bag misinformation campaign”.
Very probably both sides are looking to make their points by reducing or ridiculing their opponents point of view. But the overall issue is still there – are plastic bags affecting our environment?
To get back to the plastic bag banning situation, where paper bags have the negative effect of more trees cut, the information that is being retrieved is very important. But it must also be as objective as possible. Having said that, we know that it takes literally centuries for plastic to degrade and this should be the foremost argument.
Just to expand a little on the paper bag argument, which is totally reasonable, the option is not to cut more trees. The options are to recycle and use bio-degradable alternatives.
In the old days, when plastic bags hadn’t been invented but grocery shops had, natural fiber bags were used and the customers were the ones who brought their own to the shop.
With just a little effort on the individual front, these campaigns wouldn’t be necessary.

Save the Planet – Sell Your Laptops
Save the Planet – Sell Your Laptops
We’re in this environmental mess because humans have exploited the earth for personal gain. However, you can sell your laptops, get some grocery money and still help the planet.
Steer clear of the attitude that everything is disposable after a few uses; do your part and extract the most out of your electronics. In carelessly tossing away our possessions, we are the reason that one more thing spends an eternity in a landfill. Electronics, including laptops, are one of the most significant sources of toxic heavy metals, including cadmium, lead and mercury, leaking into the soil, according to the Environmental Protection Agency.
Pollutants do no simply stay within the confines of the landfills, but are transported through waterways and through the air. When toxic metals travel upward during evaporation, these toxins contribute to acid rain, spreading the heavy metals for miles. Dr. Lorris G. Cockerham, former professor at University of Arkansas and researcher, wrote that build up of toxic heavy metals in animals damages their vital functions and hinders growth in plants, therefore irrevocably harms ecosystems.
The heavy metals seep into waterways and into our water sources. These heavy metals can enter our body through the ingestion of contaminated water, harming our bodies. Even a low concentration can harm us, according to James Girard, author and professor at the American University.
A solution? Sell your laptops to a recycler. When you sell your laptops, the laptop parts find new life with computer repair shops and wholesalers, avoiding certain doom in a landfill. Selling laptops is an easy process for the average time-constrained American worker. Search for “sell laptops” on the Internet. Locate a recycling company who will accept the laptops you are selling. Lastly, look for the V logo that signifies the company is verified organization, not a Nigerian scam. Many business will offer an instant quote on their Web site for the laptop you are selling. Input the specifications of your laptop, follow directions and you have check or a PayPal payment for your laptops.
Make sure you choose a reputable company to sell your laptops to. Some companies boast a “green” philosophy, but actually ship laptops to landfills in developing countries. We all have a part in this green earth and many of us have take steps to follow the mantra, “reduce, reuse and recycle.” Many people think about selling their cans, bottles and such and don’t think about their computers. Do your part, keep our Earth Green and sell your laptop.

Earthday Business on Your Mind?
The sun is shining across the hills of West Cork as I listen to the story of Earthday told by a team of evangelists with nothing but Earthday business on their minds. In 2008, visionary Simon Ford started a group to bring like-minded, positive people together in socially conscious activities. He called the group Social Traffic and right now that group has Earthday business on its mind.
The group’s first major campaign centers around Earth Day with an event named, Earthday Birthday a global birthday party for Mother Earth. Earthday 2009 and the celebrations that will go with it is all set to clamor its way across the social media landscape like some all embracing vine, covering the sometimes harsh elements of the online world with a softer, greener facade which many hope will last for more than a lifetime.
Earthday 2009 is a global celebration and a day to spread awareness of people’s destructive impact on the planet. But before you jump right in there and start changing the world on a massive scale here’s a few simple things you can do to make a difference right now, tomorrow and every single day after that.
Here’s my list of top five things to do to celebrate Earthday 2009 and reduce your impact on our planet;
1. Plant a tree or two. If you’re feeling energetic plant a whole field full.
A tree will absorb CO2 and other forms of pollution, provide a home to hundreds of creatures, help to create and retain soil and performs a whole host of other ecological functions. And, in case you needed a reminder, will leave a lasting legacy of your time on the planet.
2. Walk to work for a day, a week or a whole month. You’ll feel better and the earth will be a much healthier place to live too.
You might even want to think about joining a car sharing scheme and make it a permanent part of your work life balance to drive to work only one day a week and sleep the other four in the passenger seat while someone else does all the hard work!
3. Dry your dishes naturally. Turn off the dishwasher at the dryer stage of the cycle and leave your plates and cutlery to dry themselves for a change!
4. Turn off all your plug sockets before bed. Maybe spend the evening in the dark for one day a week and treat the kids to a few ghost stories before bedtime!
5. Don’t be a water importer.
Get rid of your supply of bottled water, keep a jug of fresh tap water in the fridge and reduce the damage we do to the environment by producing plastic bottles to hold gallons of mineral water that tastes no different to the clear, fresh water that is piped through your home.
So, if you’ve got business on your mind this Earthday, perhaps you should take a few minutes to look around you and realise how precious our planet is and how beautiful that small piece of turf is right outside your window.
If you want to know more about this subject and how you can make a difference take a look at this great squidoo lens all about Earth Day Birthday right now.
Neil Ashworth is a member of Simon Ford’s Social Traffic Team who are raising awareness of environmental issues using the power of social media marketing to support the Earth Day Birthday campaign.
Antarctic Peninsula Climate
Antarctic Peninsula Climate
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Do We Want Too Much?
Do We Want Too Much?
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
