What do all these accomplished people have in common? They are not pursuing the latest fashion trends and basically wear the same thing all time.

Hong Kong government statistics show we create 293 tons of textile waste per day. While this is in itself astounding, what is even more vexing is how counterproductive it all is. The purpose of this consumption is ostensibly to make us feel more confident and create a memorable impression. Ultimately helping us find love, success and live the good life. Unfortunately, the pursuit of the latest trends has two huge drawbacks.  Continue reading “The Pursuit of Love, Success and Happiness”

Rooftop Farming in Hong Kong

This article was updated in January 2016. Urban farming on rooftops has been gaining traction in cities around the world. Its rise can originally be traced to consumers increasing awareness of carbon emissions that result when our food travels hundreds, if not thousands of miles from the farm to our table. As an experienced urban farmer that grows on the rooftops of commercial buildings such … Continue reading Rooftop Farming in Hong Kong

Economic Growth is Good…or is it?


“Only by maintaining Hong Kong’s stability can we sustain our economic prosperity. Only by sustaining Hong Kong’s prosperity can we improve people’s livelihood.” CY Leung July 1, 2014

This quote encapsulates the argument of the pro-China business groups in Hong Kong.  Their argument is two-fold: (1) that transitioning to a legitimate form of democratically elected government will cause instability and thus reduce economic growth, and (2) that economic growth is necessary to improve peoples lives. While we disagree with both, it is the second assertion that is relevant to the environment. It forms the justification for our most environmentally damaging behaviour.

This is the myth that we are setting out to debunk with some thought experiments. Thought experiments are favoured by scientist and philosophers, while complex models that are to a shocking extent unsubstantiated by empirical evidence are favoured by economists. (Disclosure: your author studied both economics and philosophy at the University of Toronto).

Look at the picture above. What do you see? Local residents sitting under a tree on a hot day? Wrong! That is a potential source of economic growth. Arborist’ could be employed to cut down the tree, drivers to transport it and factory workers to turn it into furniture or paper. It would then be transported back to a store to be sold by a clerk. At every stage of this “value creation” process, people are employed and income is earned resulting in economic growth. Continue reading “Economic Growth is Good…or is it?”

A Delicious Irony

Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. In a recent Mingpao article titled “Farming can make money”, the purveyors of hydroponically grown produce tout many of its impressive benefits. Chief among them was food safety.  They rightly point out that much of China’s land is contaminated and its fresh water is polluted. This jeopardises our food safety since most of … Continue reading A Delicious Irony

Year End Carbon Review

Another year has come and gone. This makes it a good time to review our personal impact on the environment. While we may all proclaim our love of nature and all the beautiful creatures, nice sentiments are not nearly enough. That time has passed, climate change is upon us. We need to be driven by facts, data and most importantly personal accountability. If we want … Continue reading Year End Carbon Review

Technology is the Answer…or is it?

In 50 years, every street in London will be buried under nine feet of manure.

The London Times, 1894

Most of us by now are aware of the challenges we will face in coming decades – climate change, water shortages and mass extinction of species to name a few. Many believe that technology will solve all these problems. That we can continue to consume as usual because human ingenuity will, as it always has, find technological solutions to our most pressing problems. Lets review the four most important technological innovations of the last century to find out if our faith is warranted.


Thomas Malthus predicted that overpopulation would result in widespread poverty, famine and war. Population did grow from 1 billion in the 1800’s to 7 billion today. However, food production also grew rapidly as a result of a set of technological innovations, known as the green revolution. The hunger and poverty that Malthus predicted never came to pass (at least for those lucky enough to be born in the developed world). The key elements of the green revolution were hybrid seeds, chemical pesticides and synthetic fertilisers. They are the foundation that makes the modern world possible by freeing up people from having to grow their own food. They are also the source of some of the most serious environmental problems today.

The petrochemical fertilisers are causing vast dead zones in our oceans and rivers. Chemical pesticides are contaminating our soil and water, and causing the loss of biodiversity. Hybrid and GM crop varieties produce increased yields, but require much greater inputs of water and fertiliser. The irrigation required to grow high yield varieties is resulting in the alarming depletion of ground water. According to Lester Brown, our current farming practices based on the green revolution, are now a threat to world food security.  The solution has now become the problem.


Before the invention of antibiotics, everyday ailments commonly resulted in unimaginable pain or even death. All the surgeries conducted today are made possible only by antibiotics. However, most of us are unaware of the fact that over 60% of all antibiotics produced are not consumed by humans.  Instead, they are being fed to livestock not to prevent disease but to enhance growth, so we can buy cheap meat. As a consequence of this widespread use, drug resistant bacteria are proliferating.

A recent Australian report says there is ‘a genuine threat of humanity returning to an era where mortality due to common infections is rife’. According to Australia’s top scientist, the overuse of antibiotics is threatening to return us to a world where deaths result from minor ailments such as sore throats and cut knees. England’s chief medical officer, Dame Sally Davies, warned in a March report that untreatable infections posed a “catastrophic threat” to the population.


In the 1900’s, there was a horse-manure crisis. In New York, a population of 100,000 horses was producing 2.5 millions pounds of manure a day. The streets were covered with manure and air was thick with flies. The technological solution came in the form of cars and buses powered by fossil fuel. The manure crisis was averted.

Cost Benefit Analysis of Golf


Golf has been in the news recently because it has been proposed that the government take back the land that the Hong Kong Golf Club (The Club) sits on to develop housing. It is argued that it would be preferable to eliminate the golf course rather than relocate villages and destroy farmland. In order to ascertain the validity of this assertion, we should examine the costs versus the benefits of golf.


The benefits of golf have been clearly articulated by the local golfing community as they seek to justify the taxpayers continued subsidy of their exclusive, members only Club:


In a recent SCMP article, a representative of The Club justified its existence on the basis that Hong Kong is an international business centre and golf plays a big role in business (lots of business gets done on a golf course). As a professional starting out in my career, I remember how golf was a constant topic of conversation around the office. Many of my bosses were avid golfers and corporate events were often golf trips followed by BBQ dinners. So yes, I do believe there is a connection between golf and business. It might be a stretch however to call it an important one. There has been no research that links golf to economic development (as there is with education, infrastructure and the rule of law). If there were, Scotland and Thailand would be business superpowers today.


William Chung Pui-lam, president of the Hong Kong Golf Association, said growth of the game – recently made an Olympic sport – would suffer if the Hong Kong Golf Club’s three-course, 170-hectare facility at Fanling were lost to housing. Bobsledding is an Olympic sport, and its development is also suffering due to lack of venues in Hong Kong. Perhaps we should also dedicate public resources to its development?


Another housing adviser, Lau Ping-cheung, said the land use of golf courses should be reviewed together with all other private recreational clubs. “But we need to discuss and understand the possible social impact, because Hong Kong is an open city with lots of rich people and foreigners who might be interested in golf.” Rich people also like private jets, perhaps we should subsidize runways for private jets as well?


Golf commentator Dominique Boulet, a former Hong Kong representative and a member of the club for almost 30 years, said: “If we lost the Hong Kong Golf Club, I’m not sure I would live here any more.” I never realized how much I would miss Mr. Boulet until he threatened to leave. In fact, I had never heard of him before he made this statement to the SCMP.



NY States Attorney General’s office published a report entitled Toxic Fairways. The report, which was particularly concerned with the potential for groundwater contamination, concluded that these [NY] golf courses applied about 50,000 pounds of pesticides in one year, or four to seven times the average amount of pesticides used in agriculture, on a pound per acre basis. Pesticide and fertilizer runoff contaminates ground water, poisoning both humans and wildlife.

It is quite ironic, the number of golf charity events held to raise money for cancer research when there is  evidence of major excesses of non-Hodgkin’s lymphoma, brain, colorectal and prostate cancers in golf course maintenance workers and superintendents exposed to high concentrations of carcinogenic herbicides and fungicides. The cost of cancer treatment for golf course workers will undoubtedly be borne by the taxpayer funded public healthcare system.

Outsourcing Meat Production to China

polyface farm

While out searching for farmland one day, I encountered an elderly woman at the bus stop and struck up a conversation with her. When our conversation turned to farming, she recalled that she used to grow vegetables and raise chickens, and that this practice significantly reduced the amount of pests she had to deal with. The chickens pecked at the ground, eating the pests, and the seeds (and roots) of weeds. By simply feeding themselves, the chickens helped her to dramatically reduce pest and weed problems without  using any chemicals!

In the past, many farmers also raised pigs that were fed with plant waste. This created another win-win situation. The plants and parts of plants that humans didn’t or couldn’t eat were used to fatten up pigs. Plant waste was recycled as pig feed. Kitchen waste (that now makes up 40% of the garbage going to our landfill) was also turned into pig feed. According to the SCMP, the recent increase in the garbage going to our landfill can partly be attributed to the reduction in the number of pig farms in Hong Kong.

Paper Books vs. Online Content


This article will explore the widespread belief that e-books and online content is environmentally more friendly than hard copy paper books. First, however lets take a look at the history of technology.

The invention and adoption of every technology is a response to a problem that existed in the past. Today, we tout the coming age of (clean energy powered) electric or hybrid cars as solution to reducing the fossil fuel consumption, air pollution and CO2 emissions caused by internal combustion engine powered cars. The car however was itself a response to an even earlier environmental problem – the vast amounts of manure on city streets caused by the horse and buggy.

At the time of the invention of the internal combustion engine, no one considered CO2 emissions or climate change to be a problem. This illustrates the law of unintended consequences. We cannot foresee all the environmental impacts of technology, let alone foresee how it will be used. The internet is prime example, invented by the military for fast, secure communications, it has become a worldwide tool for commerce, social interaction and political movements (as well as porn, online gambling and Facebook poking).

The proliferation of this technology has resulted in enormous data centres, communication networks and billions of end user devices (computers, iPads, iPhones) consuming vast amounts of energy. According to Yale, Since 1990, household energy consumption has been rising worldwide at 3.4 percent a year, in large part because of the rapid spread and increasing sophistication of electronic devices. At this rate, household energy consumption doubles every 20 years.

Lets compare the environmental impact of the production, transportation, use and disposal of paper versus electronic content. Remember, all electronic content is stored on and accessed through electronic devices. This is the elephant in the room. Continue reading “Paper Books vs. Online Content”

Why is organic food so expensive?

Spraying Strawberry

As an organic farmer, I am often asked “Why is organic food so expensive?”

The simple answer is that it’s not. It is that conventional (chemical) food is cheap. Or more accurately, the price of conventional food does not reflect its true cost. Let me explain:

The introduction of chemical fertilizers, pesticides and herbicides dramatically increased yields and lowered labor input costs, thereby decreasing the price of food. However, they also imposed costs that are not reflected in the price consumers pay for food, what economist call externalities.

Chemical fertilizers are cheaper and more potent than organic fertilizers, resulting in widespread overuse. The use of these highly concentrated fertilizers has created vast dead zones in our oceans, rivers and lakes. This is a cost, but we as consumers don’t pay for it. To grow an equivalent amount of food, organic farmers need to transport and spread much larger quantities of slow-release, low concentration fertilizer on their fields which results in increased labor costs that is paid for by the consumer.

Chemical pesticide and herbicide use is contaminating ground water worldwide. Atrazine, one of the world’s most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarter of them.  So while the price we pay for conventional food is cheap, the cost to the environment is not. Without chemical pesticides, organic farmers suffer greater crop loss from pests. Since consumers will not accept blemished fruits and vegetables, organic farmers end up with significantly less salable produce. Hence, they need to sell the salable produce at a higher price in order to survive.

Finally, there is no such thing as organic herbicides, so the organic farmer must manually or mechanically remove weeds. This again, increases the cost of production and needs to be paid for by the consumer. Continue reading “Why is organic food so expensive?”
