Today marks the 48^th annual Earth Day celebration and around the world events and efforts will be taking place to draw attention to the need for stronger environmental protections.

As the global community reflects today on the increasingly sensitive state of the planet and what role we as individuals can play in tackling what can sometimes feel like an overwhelming issue, it’s important to remember that every time we sit down to eat, we have an opportunity to stand up for a better world.

Animal agriculture has been identified as a leading contributor not only to climate change, but to air and water pollution, water use, land degradation, deforestation and biodiversity decline.

In fact, animal agriculture is responsible for more greenhouse gas emissions than the entire global transportation sector. This is because animal-based foods are incredibly inefficient to produce and are very resource-intensive. The processes involved when it comes to raising, transporting and slaughtering animals for food are responsible for potent greenhouse gas emissions including carbon dioxide, methane and nitrous oxide. To put this in perspective, beef production requires 20 times more land and emits 20 times more greenhouse gas emissions per unit of edible protein than common plant-based protein sources such as beans, peas and lentils.[1]

The production of animal-based foods also requires and pollutes large amounts of water. Agriculture accounts for 92% of our global freshwater footprint; approximately one third relates to animal products.[2] The water footprint per gram of protein for milk, eggs and chicken is approximately 1.5 times larger than for pulses (beans, lentils, peas). For beef, it is six times larger than for pulses.[3] The sheer volume of animal waste, along with fertilizers and pesticides used for feed crops, as well as hormones and antibiotics used on livestock create major water pollution issues. These pollutants seep into waterways, threatening water quality, ecosystems and animal and human health.[4]

Meanwhile, animal agriculture is a key contributor to land degradation and deforestation, with one-quarter of the earth’s land surface (excluding Antarctica) being used as pastureland. [5] The conversion of natural habitat to accommodate livestock and feed crops puts immense pressure on wildlife that struggle to survive in increasingly fragmented and degraded environments. Ineffective and ill-informed cull programs put additional pressure on predator populations, due to the perceived threat they pose to livestock profits.

While our diet can be a major part of the problem when it comes to protecting the planet, that also means it is a crucial part of the solution. A 2016 Oxford Martin School study found that the adoption of global dietary guidelines would cut food-related emissions by 29%, vegetarian diets by 63%, and vegan diets by 70%.[6] By reducing and eliminating resource-intensive animal products from our diet and supporting efforts to make more sustainable plant-based foods widely accessible, we can drastically decrease our individual and societal environmental footprints.

This Earth Day, join the growing number of people around the world who are recognizing the power behind what we put on our plate. Take our Meatless Monday pledge for recipe ideas and download our Live Well booklet to learn more about a plant-based diet. You can also support VHS’s efforts to introduce more healthy, humane and sustainable plant-based menu options in schools and other institutions.

The horsemeat scandal that has rocked Europe may be just the tip of the iceberg, as new revelations about the food supply emerge. European consumers expressed revulsion when it was revealed that frozen lasagne and other products where contaminated with up to 100 per cent horsemeat.

But now a new shock about food products has turned the stomachs of shoppers and diners in Britain and across the continent: It has emerged that the flesh of other dead animals, not just horses, is rampant throughout the food system. For example, it has been revealed that dishes such as roast lamb and lamb stew actually contain the flesh of a baby animal of the same name. Investigators have also discovered that the entrée known as veal is made from another baby animal called a calf. There are now indications that the entire human diet may be contaminated with the flesh of a range of dead animals.

British consumers interviewed about the revelations were appalled. “You mean every Sunday I’ve been eating one of the cute little spring lambs I’ve taken my children to see in the countryside?” said one horrified woman.

A man in a pub refused to finish his lunch when told that steak and kidney pie actually contains the organs of a slaughtered animal. “What, you mean the kidney is actually a kidney?” said the disgusted diner.

Another diner, who said he had been sick to learn about horses being used for food because they were so sensitive and intelligent, was dumbstruck when told that his ham sandwich was made from a sensitive and intelligent animal called a pig.

Government officials have suggested that the contamination may be the work of “organized criminal gangs” who have introduced the flesh into the food chain. There are dark rumours that this may even have happened on a global scale, with so-called “factory farms” keeping billions of animals in inhumane conditions before killing them and distributing their body parts for huge profits.

However, scientists and bureaucrats have dismissed the rumours, stating that it’s unthinkable for such a cruel system to exist. “It’s impossible to believe that anyone could organize something so brutal on such a scale,” said one official. “No civilized society would ever allow such a thing to happen.”

An environmental expert said such a system would also be unsustainable. “It would use up an enormous amount of resources, pollute our air, land and water and contribute to climate change through massive releases of greenhouse gases,” he said. “The human race would never be so self-destructive.”

And health officials say that if people were eating a diet heavy in animal flesh we would be seeing high rates of obesity, cancer, heart disease and diabetes. “It just couldn’t happen,” said one medical expert. “It would be almost suicidal for society to take up such a diet and we’re a lot smarter than that.”
