Hello, my name is Margaret Asmuss. I've been involved with environmental issues since 1982, when I first was a summer student for the Saskatchewan Environmental Society. That was also when I first learned about climate change. I'm concerned about climate change because I'm a mother and a grandmother. My name is Glenn Wright, and I've been concerned about climate change for almost 20 years. I farm near Vanscoy, Saskatchewan, and I've been trying to take every action I can to reduce my impact to address the problem. Glenn and I are going to be having a conversation about how the climate crisis needs to make us evolve our culture, our attitudes, and the way that we do things. But before doing that, we'd like to acknowledge that we are on Treaty 6 territory, which is the traditional territory of the Cree, the Saulteaux, the Stoney Dakota and Nakota, as well as the traditional homeland of the Metis. In recognising that we all have benefits and responsibilities under these agreements, we also acknowledge past and present harms and injustices, including the degradation to the land of this territory. Anybody who watches the news knows that extreme weather events are increasing. Just today, a report was released by the Copernicus Climate Change Service in Europe that confirms that 2023 was the hottest year on record, and that every day last year was at least one degree above the pre-industrial level. And this has an impact on climate and on weather patterns. And we can certainly see that when we watch the news. Last year was full of news about wildfires, torrential rains, heat waves. So, worldwide, we see that there's a lot happening. In Canada, 80% of farmland is currently experiencing extremely dry conditions, and we certainly saw the wildfires in B.C. last year and the spreading of that smoke throughout North America, and some even into Europe. Here in Saskatchewan, we've also had impacts. We have a number of regions that have been experiencing extremely dry conditions. We've had record high temperatures, and certainly last summer we all remember the decreased air quality due to fires here and elsewhere. So, the changes are clear to most people. But why is this happening? Well, we are emitting what are called greenhouse gases. As a society, the majority of these are fossil fuels, but not exclusively. And these greenhouse gases are getting trapped in the atmosphere and making the atmosphere become warmer, which is changing weather patterns. That's a very simplified version of the science, but essentially, this increase of greenhouse gases and the trapping of those gases is changing weather patterns. What about Saskatchewan? Per capita, Saskatchewan is one of the largest emitters in the world. We have just 3% of Canada's population, but we emit about 11% of the greenhouse gas emissions. Why is this? Well, I don't think we set out to be polluters, but Saskatchewan sits on rich reserves of fossil fuels, including oil and gas and coal. And we use those reserves for economic development to bring our province forward. And certainly, they were very useful and created a lot of benefits to the people of Saskatchewan. But at the same time, they increased our emissions of greenhouse gases without us really realizing what the implications would be. Now that the climate crisis is here, we really have to pivot away from those ways of life and the technologies that have been creating these problems. Most of us understand that as a society, we need to evolve away from fossil fuels through such things as increasing renewables increased energy efficiency, improved mass transit, improved electricity transmission. So, I think we understand that as a society, that that is a necessary evolution that we have to move toward that. And certainly that's happening throughout the world, and needs to start happening here too. What is less understood is the role of agriculture and food systems in climate change. And this is why I've asked Glenn to come and have this conversation with me, because as a farmer, Glenn has been thinking about climate change and food systems for a long time and has done a lot in his farm, in his farming operation, to address those concerns. So, Glenn, how has agriculture changed the prairie landscape and what does it mean for us and for our climate? Well, Margaret, the agriculture system in Saskatchewan has changed, much like North America has. And that's really the result of two revolutions. The first revolution would be mechanization. So, this is moving from horse-drawn equipment and draught animals to using diesel fuel to run our big machines. So, that mechanization revolution was the first way that we became very reliant on fossil fuels. The second revolution, though, was a chemistry revolution, where we learned how to turn natural gas into nitrogen fertilizer. And that brought the Green Revolution, the more productive land by applying fossil fuel-based inputs to the land. So, these two things have really transitioned our landscape. But at the same time, we've also made many land system changes to the prairie landscape. What was once a grassland with many wetlands and prairie potholes that would hold water, most of those potholes, in many cases have been filled in. So, we've levelled the land and we've drained some of the wetlands so that we can make each acre more productive. So, we're now farming from corner to corner. And so, this evolution of our agriculture in Saskatchewan has really been to double down and focus on fossil fuel for our inputs and producing our food. But at the same time, it's driven up risks, risks that are tied to climate change. Without those prairie potholes to buffer and hold water in extreme rainfall events, we now have more runoff that can go into closed watersheds and cause problems. And we know that climate change is only going to bring more extreme droughts and more extreme flooding. So, this is where these these acts to drain and fill in properties and level them causes more risk for our agriculture system in Saskatchewan. But this is a complex issue, isn't it? It's related to all sorts of other environmental problems and limits of our natural landscape. Absolutely. And we have to think, too, about energy flows in our whole food system to begin with. And so, agriculture, the primary production, is only one component of how our food goes from production to the table in front of us. We have also all of the transportation. We have the processing, we have refrigeration, we have the marketing and the wholesaling and distributing, in addition to the preparation that happens in the home, where we use energy to cook and prepare our foods. So, what's happened is our whole food system has turned from what used to be an energy source, where we would get energy from photosynthesis in the sun. It's now an energy sink, because we were so reliant on fossil fuels to produce our food. And the real travesty here as well is about a third of our food is wasted through the whole food chain. So, these are the things we need to tackle to make our food system more sustainable. We have to replace the fossil energy with clean energy, and we have to reduce our impacts and reduce the waste. Well, you're a farmer, and you've been thinking about this for 20 years, as you said. What has to change and what have you changed? Well, if I could take a step back, the first thing I would say is that it is a very complicated system. And it's not just about climate change. Yes. And so I'd like to touch on a concept called the planetary boundaries. And this was introduced by the Stockholm Resilience Centre in Sweden. And so what they did in 2009 is they kind of took a look at the Earth, and they determined that there were nine planetary boundaries that human-to-human activity is influencing. But just last year, they finally quantified a bunch of like an assessment of each of these boundaries and found that six of the nine are actually operating outside of a safe space. So, beyond the sustainable operation of the planet. And what's really troubling for me as a farmer is that five of those nine planetary boundaries impact our food system and our food production and agriculture. So, these are things like climate change certainly is one of them. But fresh water, land system change, biogeochemical flows. So, this is the flows of nitrogen and phosphorus. This is the inorganic fertilizer that we're applying to grow our food system. And the last one is biodiversity. So, as we've taken over and evolved and changed these landscapes to reduce the habitat and alter grasslands and eliminate wetlands. We're at the same time reducing habitat and reducing the biodiversity available for, you know, for nature and some of the eco services they provide, like pollinating bees and things of that nature. So, from my perspective and my farm, I've been trying to think always of how do I reduce my impact and how do I replace the fossil energy with clean energy? Okay. Well, tell me about that a little bit and how that relates to the bigger picture, like what you think has to happen within the agriculture and food services industry? Not food services industry, but what's the right word? The food system. Yes. I think certainly as we electrify things, we're going to be using less energy because when you electrify something, it generally uses a third to a quarter of the energy of a combustion process. So, think of the transportation, moving the food from the fields to the processing plants. And likewise, if we clean up our electricity instead of having fossil energy driving our electricity, if it becomes clean electricity, then all of the refrigeration and processing we do will become less emissions intensive. So, there's a real connection between what we do on the energy side and what we do on the agricultural side. If we clean up the energy picture, we're also cleaning up agriculture. Absolutely, absolutely. And fossil fuels have been a tremendous gift for us. They've allowed us to to grow human enterprise at a massive scale. And it's because they're so energy dense. The amount of energy in one barrel of oil is about the same as a human working for eight hours a day for four years, and that only costs $100 for a barrel of oil in Canadian dollars now. So, that's why we've become so addicted. But the waste products are causing us to exceed those planetary boundaries. So, when I think about my own farm, I'm always thinking about how do I reduce my emissions intensity, reduce the fossil fuel inputs, and also trying to think of ways to be more efficient and to reduce the amount of waste. So, what we've been doing is trying to go to what I would call a reduced input farming, because most of the emissions tied with our primary production and agriculture are related to fertilizer, nitrogen fertilizer and phosphorus fertilizer. Nitrogen in particular is one of the worst offenders because it's primarily derived from natural gas. And it is one of the most potent natural greenhouse gases, isn't it? That's correct, yes. So, I think as I mentioned before, we had two revolutions, the mechanical mechanization and the chemistry revolution, both tied to fossil fuel. I think we're just beginning a third revolution, which I'll call the biological revolution. And so, this is going to be a way for us to reduce our dependence on fossil fuel. So, for instance, certain plants are able to fix nitrogen from the air just because the air we breathe is 78% nitrogen. So, these types of plants are often referred to as pulse crops. So, these are things like peas and lentils. So, if we can incorporate more of those crops and grow them in an intercropping manner with others, then you can have nutrients come from the-- Excuse me. You can have nutrients coming from the pulse plants to make it bioavailable for others. Okay. Well what about the use of animals? I mean, certainly the grasslands evolved with the buffalo. We no longer have them. What sort of role do they play in all of this? Animals are one of the items that often gets focused on as a distraction, I think, from the oil industry and methane emissions. We typically see cattle being attacked for their methane emissions. And it's true that we probably have to move away from intensive livestock operations where we're dragging all of the inputs in. Again, depending on transportation and high emissions intensity. If we can get to animals that more replicated what used to happen in nature, grass-fed beef, for example. We also know that there's a really important relationship between building soil health and incorporating animals. So, this is about building organic matter and providing, nutrient use efficiency and growing the diversity of the bacteria and microbes and fungi in the soil. Building soil health is going to be one way that's really important to be resilient to climate change and extreme weather. Okay. Anything else that you want to add that we haven't been able to touch on? Well, I would say that it's really important to think not only about what individuals can do, but what the industrial system needs to do. And I think our farm has been a good demonstration of that, because I did take time to focus on installing renewable energy, doing a retrofit on my house and eliminating the natural gas supply to our farm. So, we now save about $6,000 a year in fossil fuels that we used to buy, and we've reduced our household emissions by about ten metric tons per year. But the amount of change that happened on the farm in the grain crops that I grow by using less fertiliser is probably ten times the amount of emissions. And so I think this is why we have to do everything all at once. We have to have individuals taking action, but we need policy from governments to drive us towards that clean future that we that we need to accelerate. And how do we get to that future? Any last words of wisdom? Well, I guess my last words of wisdom would be that when you learn about the climate crisis and these other planetary boundaries, it's understandable to be afraid and to sometimes even be paralyzed with fear. Or to become angry and get upset with corporations and governments. And that's justified. But I think of Doctor Martin Luther King, for example, and he didn't win people over with speeches talking about how he's fearful and angry. He never said, I have a nightmare, for example. He said, I have a dream. And that dream we need to focus on is clean energy and reducing our impacts and replacing fossil energy with clean energy. And I think it's possible we just have to accelerate towards it. Okay. Thanks a lot. You gave us a lot to think about. Thank you.
