Agriculture
The Quiet Giant of Food and Agriculture
It brings the past much closer when we consider that many people alive today had grandparents that lived through part of The Industrial Revolution. To put that in context, Napoleon reigned during part of that revolution.
The grandparents of today’s 90 year olds lived through an explosive part of history. They saw the advent of everything from electricity, to indoor plumbing, public health, billionaires, cities and pollution –all of which began to create entirely new realities for humans to adapt to.
During that time mankind made several key discoveries that we still rely on heavily to this day, and yet those discoveries are almost completely hidden by time. This is about such a discovery.
It’s important to note that The Industrial Revolution was largely an unintended consequence that emerged from geographical/cultural discoveries, as well as those made through the sciences; in chemistry, engineering, material sciences and analytics. And it couldn’t have all come at a better time, for the population was exploding along with our technologies.
1851 was the first year in history that any nation had more people living in cities rather than in the country, and that in and of itself was a sign of the revolution. As machines made agriculture easier, it freed up almost half of society to pursue careers off the farm. It is still the case today that absolutely every other job on Earth depends on farmers to ensure every other worker has access to a stable food supply.

Agricultural efficiency meant London, for a long time the world’s largest city, had 2.5 million residents by 1850. There were tremendous hardships during that growth period without a doubt. But there is also no question that people’s lives were improving faster than ever before thanks to both science and technology.
To celebrate London’s modernity, 1851 saw the construction of the largest and most impressive building ever seen. At close to 77,000 square meters (19 acres) it was awesome by the day’s standards. But more than that, it was also the world’s first well-lit building, for The Crystal Palace got its name thanks to being constructed from over a quarter of a million panes of the recently invented marvel, plate glass.
Inside were the discoveries and creations that were powering the Industrial Revolution. The bright building was filled to the brim with exciting and revolutionary things like toilets, which –when you stop to really think about it– were quite the marvel for people who had always lived without them.
But what other kind of wonders did they put in such a museum of technology? What technological discovery was so incredible that it warranted its own display space as well as notation here, 170 years later?
The reason we should care about the answer to that is because, in essence, at least one of those featured items was –and still is– very much responsible for most of us being alive today.
Food Security
In the 300 years between 1500 and 1800, on average there was one famine per nation per decade. Imagine not eating one year in ten! That was totally normal for 300 years, and before that things were routinely worse. Then, in the late 1700’s Europe’s hope began when potatoes first made their way from South America.
The versions from back then had high levels of natural toxins that the South American natives dealt with by eating clay along with their potato. Many animals do this, and in the case of humans, the clay binds to the toxic glycoalkaloids which prevents them from entering the bloodstream, thereby offering the eater protection.
Rather than teach Europeans to start eating clay, instead, a man named Antoine-Augustin Parmentier did some impressive potato breeding and reduced the toxins in several breeds of potatoes, relatives of which many of us still consume.
Coincidentally and rather famously, King Louis the XVI chose that time to make grain far more expensive with a tax. We all likely recall that his wife, Marie Antoinette, is reported to have suggested to the peasants who couldn’t afford bread that they should make pastries instead (aka “let them eat cake”).
Of course, the Queen literally lost her head to the guillotine, but that tax and the potato’s reliability soon lead to the spud making up 30-60% of a European’s diet. The simple fact was, tubers failed less often and were actually quite healthy.
By the latter half of the 1700’s most Europeans consistently had enough healthy food to eat for the first time in history. As with all animals, that lead to people having more children, which meant agriculture was forced to keep pace.
The next major piece of modern food puzzle dropped into place in 1840 when a chemist with the rather awesome name of Justus von Liebig figured out that plants needed nitrogen to create chlorophyll. Boom.
Chlorophyll is what allows plants to eat light.
Everyone knows about compost and manure and fertilizer today. But before Justus von Leibig, no one realized that nitrogen and potassium were key components to plant growth.
Remember Jr. High science class? Chlorophyll is that stunning green molecule that can absorb light energy and trade electrons with other particles. In doing so it can create a form of energy that converts the sun’s energy into mass. Chlorophyll is what allows plants to eat light.
It’s a stunning idea that’s in front of us every day. Plants eat light. Imagine if we could just put a baby in the sun and we only gave it water and a few chemicals, but it grew like it had eaten lots of really healthy food. It’s stunning. Miraculous. But to make that wondrous chlorophyll, Justus taught us that plants need plain old abundant nitrogen.
The Earth’s air is mostly nitrogen, but in our air the bonds on the nitrogen are so tight that the plant can’t tear them apart to make use of the chemical it needs. It’s like we’re the plant and we’re starving, and someone gives us a pull-top can of beans but the pull-top has no tab to pull so the can is impossible to open. It’s the same for plants with airborne nitrogen.
That air bond being as tight as it is, plants prefer to absorb nitrogen through nitrates in the soil they grow in. But over time those naturally get depleted because we keep carting harvests off the same soil. We do have to eat, and the plants use the nutrients to power their growth systems, so it becomes easy to see why the nitrogen replenishment issue was and is a real challenge for humanity.
Just because Justus knew nitrogen worked didn’t mean farmers or plants had a source of it. Fortunately, the world’s discoveries were hardly over.
By the 1830’s, Darwin and others are venturing past Argentina into the Pacific Islands where they are starting to find places so heavily populated with birds that entire islands were covered in bird poop 50 meters (150 feet) thick. At the same time, other Europeans in South America were noticing that the natives curiously traded in bird dung….
As many might guess, the connection between the South Americans trading in bird poop cross pollinated with Justus von Liebig’s discovery. That quickly converted Pacific Islands covered in poop into a places covered in nitrogen gold.
Guano was soon so valuable that by 1856 the US Congress had passed an Act that unilaterally gave the US the right to seize any unclaimed islands they found that were covered in bird poo.
Back in Europe, people added nitrogen fertilizer to potatoes and machines to the fields. Shortly thereafter, the world rather suddenly had the best-fed population in world history, using fewer people to grow it than ever before. But just like other animals have more young when their food supply is ample, human animals did likewise.
Before anyone knew it, the world saw its second population explosion (the first was after the initial discovery of the store-able grasses –wheat, corn and rice– 12,000 years earlier). That flood of food-security births was further compounded by baby booms following two World Wars. By the 1980’s popular predictions for the 70’s, 80’s and 90’s suggested hundreds of millions of people would be starving to death every year. But….
Once again, science came to the rescue with improved breeding by Norman Borlaug, the father of The Green Revolution. Again fertilizer proved its importance by playing a key role in powering Borlaug’s new crops.
By then we were running low on bird dung, but around that time the Haber-Bosch process proved it could turn airborne nitrogen into the fixed nitrogen farmers could use. It saved billions from starvation and yet very few people are even aware of its critical importance.
But what has all of this got to do with a display in a huge glass building in London, 100 years earlier, in 1851? What kind of wonders did they put in a plate glass museum of marvelously shocking technology? What was so incredible that it warranted its own display space? A place of honour and distinction?
The answer? Some of that South American bird poop. Chemicals. Fertilizer. Nitrogen. People lined up to have a look. Today we take it completely for granted, but it was big news for people used to starving one year in ten. They were excited to see the stuff that was keeping their bellies full. They marveled at it, as we should as well.
Indeed, synthetic nitrogen has its price to both farmers and the environment. But it must be weighed on balance, because even today there is no escaping the fact that it is our only viable way to generate 50% of the world’s food. At this point in history, it is literally irreplaceable.
At a time when innocent ignorance and chemophobia are threatening to take away some of society’s most valuable tools, it’s important for people to understand the value of smart chemistry.
The world has serious challenges, but it is also achieving stunning things. If humans from the 1700’s and 1800’s managed to convert bird poop into a tool that feeds 3.5 billion people, then there are many reasons to be optimistic in a world filled with more brilliant scientists than ever, especially considering the fact that they are working in a world that sees human knowledge double every single year.
Why Canadians Should Care About Land Loss
Developments are increasingly taking over Canadian farmland. Farms once took up much of Canadian land. However, that case is not true today. Only about 5% of Canada’s land is considered prime farmland. This prime land borders one of Canada’s fastest-growing regions, and once suburban development overtakes it, Canadian farmers will have a challenging time providing food for the cities.
Farmers in Canada make their livelihood by planting, growing, harvesting and distributing food to the Canadian populations. Without land, both farmers and the rest of those living in Canada will not get fresh, Canadian grown produce.
Here are some reasons why Canadian farmers should care about land loss:
- Farmland Provides Food
While this is an apparent reason, it’s an essential one. Prime farmland in Canada produces food for major Canadian cities. As farmers continue to lose land, they have to rely on a smaller acreage to make the same amount of food — if not more — for the growing population.
Over the past 10 years, almost 1 million hectares of agricultural land has diminished due to development and growing populations. Agriculture continues to adapt to land loss. However, further technological advancements must first take place to grow enough produce vertically rather than horizontally.
- Land Preservation Will Help the Economy
Farmland preservations come with a wealth of economic benefits. Agriculture contributes to the economy through the following ways:
- Sales: For the economy to survive, there needs to be consumer demands and sales. Almost everyone purchases produce, so there will always be a demand for those goods. Without land to grow agricultural products, no sales will be made, and the economy could suffer.
- Job opportunities: Less than 2% of Canada’s population works in the agriculture industry. While it’s not much, that’s still over 750,000 people. Preserving farmland shows a commitment to the industry. Land loss would create job loss. However, maintaining the farmland — and even reclaiming it, along with pastures — could boost the sector and, therefore, the economy. It would provide unemployed people with job security.
- Secondary markets: Farmers are just one part of the food business. Because of farmers and farmland, secondary markets can thrive. These would include processing businesses, restaurants, schools, grocery stores and even waste management companies.
Canadian farmers should care about land loss because standing back and allowing companies to overtake the farmland could seriously affect the economy.
- Farmland Benefits the Environment
Wildlife often depends upon farmland for both food and habitat. Various types of farmland create diverse habitats for many different species. Without land protection, these habitats and food sources would be destroyed, leaving many animals without a place to survive. Many would have difficulty finding a native habitat.
Additionally, growing crops helps eliminate some of the carbon dioxide released into the air. Air pollution could decrease for Canadian cities as long as no more farmland is used for development.
One major problem occurring with Canadian farmland is desertification. This happens when the soil loses nutrients and becomes barren. The urbanization of Canadian farmland is the primary contributor to desertification, which speeds up climate change and harms the environment. Keeping farmland as-is will slow down climate change.
- Land Loss Affects Farmers’ Jobs
Perhaps the main reason why Canadian farmers should care about land loss is because their livelihood could be taken away. If they don’t have the means to keep up with technological advancements in the agricultural industry, they will not be able to continue their jobs if they experience land loss.
Agriculture is an essential industry. Not everyone can pick up the skills needed to grow their own food, and so many people depend upon farmers for nutrition and goods.
Take a Stand to Preserve Farmland
Farmland is a worthwhile and precious resource for many people. Reduction in farmland acreage will hurt Canadian farmers and the rest of the population, the economy and the environment. Taking steps to prevent more land loss can slow the rates of destruction and keep natural habitats thriving for both humans and animalls.

Canadian Agriculture More Energy Intensive, More Efficient
It’s no secret that agriculture has contributed to climate change through various means. For example, you may know that livestock generates greenhouse gas emissions due to how farms process it. That said, it’s now clear that farmers have found sustainable ways to offset those contributions. In Canada, it’s all about energy use.
Here’s how Canadian farmers have become more efficient as they raise crops and livestock, setting a standard the world should follow.
Energy Demand and Consumption Have Fluctuated
The demand for energy has increased across the agricultural sector as a whole. However, it’s key to note that farmers have begun to use less energy despite that fact. That points to more efficient practices. The farmers who complete their work productively save time, money and energy. As a result, Canadian workers have reduced their energy consumption per dollar by 17%. That’s thanks to sustainability.
The most common energy sources include fuel, gas and electricity. It’s how farmers use those resources that counts. Combined with technology choices and new practices, it’s clear that efficiency is more achievable than ever.
What Contributes to This Phenomenon?
It’s crucial for people in agriculture to explore eco-friendly alternatives. The grasslands that many western Canadian farmers cultivate contains excess carbon, so you can imagine what the country as a whole holds underneath its surface. Farmers have now adopted new methods to adjust how they harvest their crops. These systems are better for production, as well as soil and seed health overall.
The agriculture industry has gone through many changes, too. There are fewer farms — but those that still operate have employed agricultural technology to be as efficient as possible. These tools include different equipment that cuts down on time to increase proficiency. Plus, it’s now more common to use solar power as an alternative to traditional energy solutions.
Why Accuracy and Precision Matters
It’s a lot easier to be energy efficient when you don’t waste your resources. The means farmers practiced before they used specific innovations often created a time deficit. If you have a smaller machine, you likely need to do twice as much work. However, when you have access to equipment that fits your field, you don’t have to be as wasteful. The accuracy and precision created by technology make this a reality.
Soil Conservation Is Led by Ranchers
Many farmers have looked to ranchers for help. It’s a native part of ranching to preserve topsoil and other elements that are inherently sustainable. As a result, it seems like ranchers have been leading the charge against climate change for decades. The tactics they use to avoid tilling soil, for example, help preserve the amount of carbon that lies underneath the Earth’s surface.
The “no-till” practice is efficient in its own right. Rather than till your soil to plant a new crop, you simply leave behind what’s already there. This method is much better for soil nutrition, and it can keep carbon exposure at bay. As a result, you have much fewer carbon emissions. In general, the idea of soil conservation isn’t a new one, but old tricks can still work alongside modern technology.
The Future of Agriculture in Canada Looks Bright
If farmers continue on this path, it’ll be clear that climate solutions are at the forefront of their minds. These efforts create more benefits for them as they save time and money. Plus, there’s always the responsibility of maintaining the planet’s health. After all, without a strong ecosystem, agriculture would suffer. Through means that are more accurate and conservative, Canadian farmers have been able to become more efficient. Click here read more stories by Emily Folk.
