The world is changing. In recent years, people have increasingly been looking for ways to reduce their environmental footprint and play their part in protecting the planet. One significant action that is often overlooked is the adoption of a vegetarian diet. Vegetarianism can be a powerful tool to reduce carbon emissions and create a more sustainable future. In this article, we will explore the environmental impact of vegetarianism and how plant-based diets can contribute to sustainability.
1. Plant-Based Diet: A Win for the Environment
In recent years, plant-based diets have surged in popularity for their myriad health benefits, but this dietary choice is also a major win for the environment. To start, animal agriculture takes up an alarming amount of resources, from water to land to energy. According to a 2018 study published in Environmental Research Letters, animal agriculture:
- Is responsible for 83% of the global freshwater use.
- Occupies over 65% of the world’s crop land.
- Generates 63% of global ammonia emissions, which contribute to air and water pollution.
- Is responsible for 18% of global greenhouse gas emissions.
It’s estimated that more than 30% of the world’s human-inhabitable land is currently used to farm animals and produce feed crops, leaving the rest to plant-based food cultivation. In turn, if everyone was to adopt a plant-based diet, it fundamentally shifts where our global resources are spent. This can result in immense environmental and economic benefits, including:
- Saving Water: Growing the same amount of food on current agricultural land requires 75% less water when it is crops instead of animal farming.
- Decreasing, not Increasing, Agricultural Land: Animal agriculture takes up three times the amount of land compared to plant-based food production.
- Reducing Global Emmissions: Target mitigation actions for livestock are estimated to reduce greenhouse gas emissions by 13% and 21%, respectively.
When it comes down to it, eating a plant-based diet is not only beneficial for personal health, but for the planet as a whole. Again, animal agriculture is a resource-intensive industry so much so that it is responsible for a large part of the world’s water stress and air pollution. On the other hand, switching to a plant-based diet can lead to more efficient resource use and improved global health.
2. Understanding Vegetarianism’s Benefits for Nature
Perhaps one of the most commonly cited benefit of vegetarianism is how it positively impacts nature. While many aspects of vegetarianism such as fewer emissions, less water usage, and the avoidance of unsustainable animal agriculture are discussed, they are just the beginning of the many advantages vegetarianism has to offer.
- Ecosystem Preservation: The drive for more land for animal agriculture is having a disastrous effect on global wildlife habitats. Re-purposing this land for sustainable plant-based farming would go a long way in restoring damaged habitats, allowing for their native species and wildlife to thrive.
- Soil Health: By avoiding animal agriculture, vegetarianism would effectively halt soil degradation from overgrazing, water poisoning, and manure application. Healthy soil is essential for plant growth and healthy nutrition, along with being the opportunity-rich environment needed by beneficial soil microbes and macro-organisms.
- Air Quality: The link between air pollution and animal farming is clear. The raising of animals produce levels of carbon dioxide, methane and nitrogen oxide that add to the already concerning state of air pollution. Moving away this type of farming and transitioning to more sustainable agriculture would go a long way in reducing these emissions.
With the growing environmental crisis, it’s more important than ever to reduce our dependence on animal farming. Embracing a vegetarian diet is an easy way to help in the fight against environmental destruction, and with more people than ever advocating for this change, we can all make a difference.
3. Evaluating the Positive Impact of Plant-Based Living
Regardless of the reason for transitioning to a plant-based lifestyle, there are numerous benefits to be reaped. Advocates of the plant-based movement often stress a variety of health advantages, but there are numerous positive influences beyond physical wellbeing. Plant-based living can have a positive impact on the global climate, as well as the local environment.
Positive Impact on the Climate
- Reduction of emissions from the production of animal-based foods and products.
- Heightened reliance on resources that are sustainable and renewable.
- Decrease in scarce resources like water, land, and forests.
In fact, UN estimates point to livestock production as one of the major contributors to climate change and global warming. A shift to plant-based lifestyles could be a major factor in changing this. A study conducted by the University of Oxford in 2018 showed that a global transition to plant-based diets could free up land for other uses, cut food-related emissions by up to 70%, and save up to $1 trillion in climate costs.
Positive Impact on the Environment
- Decreased waste and pollution from animal products.
- Livelihoods protected in the face of overfishing and animal slaughter.
- Reduced reliance on synthetic fertilizers, herbicides and pesticides.
By replacing animal products with plant-based alternatives, the environmental impacts associated with animal agriculture can be minimized. The more plant-based diets become common, the more the amount of natural resources like water, land, and forests can be saved, while the amount of waste and pollution generated from animal products can also be decreased. Plant-based diets can also have other positive impacts on the environment, such as reduced reliance on synthetic fertilizers, herbicides and pesticides.
4. The Future of Sustainable Eating: Vegetarianism and Beyond
A vegetarian diet is one of the most sustainable diets and is usually considered more eco-friendly than an omnivorous one. It requires far fewer resources to produce food, such as land and water, and generates the lowest greenhouse gas emissions. Vegetarians can easily enhance their diets with items such as plant proteins and omega-3 fatty acids to get the same nutrients as they would from animal-based diets.
But, what about the next step when it comes to sustainable eating? Eating a vegetarian diet is certainly a healthier and more sustainable option, but it is not the only one. Those looking to further reduce their environmental impact and go beyond a vegetarian diet can adopt alternative methods such as reducing food waste, supporting local farmers, or considering alternative ways of preparing food.
One of the most sustainable ways to eat is by making sure that you are only consuming what you need. Reducing your food waste can have a big impact on the environment. Use what you buy wisely and store or freeze food that will not be consumed right away. Consider composting food scraps, instead of throwing them away, to reduce the burden on landfills and create valuable soil for your garden or local farmers.
Supporting Local Farmers
- Buy fresh produce from local farmers on a regular basis
- Help support the local economy and reduce food transportation costs
- Access to fresher and often more sustainable produce
Explore Alternative Preparation Methods
- Preserving fruits and vegetables for long-term storage
- Making food from scratch and avoiding processed food
- Making use of food scraps to create nutrient-dense meals
While a vegetarian diet is a great way to reduce an individual’s environmental impact, further sustainable steps can be taken to move beyond vegetarianism. By following the tips outlined above, individuals and families can work to reduce their environmental footprint and make more conscious choices with their food.
Going meat-free is one small step that can have a big impact on the environment around us. Whether you’re a full-time vegetarian or just trying to reduce your meat consumption, opting for plant-based meals is an easy way to contribute to global sustainability. So, let’s all hop on the sustainable bandwagon and make the planet healthier for now, and for generations to come.
