Can Animals be Composters?

On my volunteering trip to a rural part of Panama, the compound at which my team stayed often had stray dogs that circulated the outdoor dinner table every night. We scared 3 or 4 different dogs away every time in fear of catching diseases they might spread, but we were puzzled as to why they kept coming back. On the last day of the trip, we found that our leftover food was being left outside every night for the dogs to feast on just meters away from the dinner table.

My team and I were shocked—in Canada, some individuals buy heavy-duty lockable trash bins or even go as far as tainting their garbage with poison to deter animals from getting to it. In Panama, they treat wild animals as part of their community. I wondered if it is because humans have a stronger emotional connection to dogs as opposed to raccoons. Or, maybe in North America we are too concerned with attracting pathogenically contagious vermin (a valid argument), and not consciously allowing our street to look “dirty”. Why are Panamanians not concerned like we are? In the previous trips I’ve been on to Central America, the cultures are often described as being much more “community-oriented” compared to the North; they have tighter relationships and interact more frequently with neighbours, and I argue that this strong sense of care to each other extends to the wildlife around them. Panamanians are more concerned with the well-being of the stray dogs in their community than the detriment to their health or aesthetic brought by the animals’ presence.

The United States Environmental Protection Agency describes feeding animals as the third tier in their food recovery pyramid, preceded only by source reduction and feeding other people.

Surprisingly, composting—the holy grail of mitigating food waste—is tier five of six on their pyramid, which puts into perspective how beneficial feeding animals our food scraps could be.

Am I suggesting you start a food scrap pile in your neighbourhood? 

No. The reality is, stray animals can still carry diseases, be nuisances, and maybe even be aggressive. Given the structure of some cities and towns, feeding animals might not be easy to do, and it is not always safe. Just because Panamanians have grown accustomed to this lifestyle does not mean it can be replicated everywhere. 

That does not mean, however, that your food waste should always be destined for the composter—which brings me to my second point. For the many of you that have pets at home, there is a large variety of foods that can be safely consumed by cats and dogs including certain meats, veggies and grains. Dogs specifically evolved alongside humans eating their leftovers, and it was not until the past several decades that industries began heavily marketing synthetic dog food. If you are unsure of what you can feed to your pets, you can always reference reputable internet sources or contact your local vet—it may save resources and your money.

Some Universities and institutions are even donating food scraps to nearby farms. Everyday, 1 ton the food scraps from the kitchens at Rutgers University go directly to the hogs and cattle of a nearby farm. The university only pays half of what it would to the city’s organic collection system, and the animals get to enjoy a healthy variety of food. If you live near farm, this extra step could be an option for you too.

Although it may not be ideal to live exactly like generous Panamanians, we North Americans can still learn from their lifestyle to reduce our food waste in an alturistic manner.


Tub or Tube?

I am sure we all know the irritating feeling of having food right in front of us and not being able to eat it, and then having to throw it away. 

But, let me be more specific—you are famished and holding a nearly empty tub of Nutella. Your spoon is just enough to reach the bottom, and the container is too small for your big hands to really have any autonomy over it. The more you scrape, the harder it becomes to fill your spoon. You enjoy any little bit you can manage to get on the tip of your silverware, but you know you will soon have nothing. And then it happens. In the midst of the adrenaline and hopefulness you had of having a fulfilling snack after a long day of work, you accept that you have lost the battle to the Nutella container and can’t get any more onto your spoon. As you lick the messy fingers of one hand, the other hand throws away a jar cumulatively containing at least a whole delicious spoonful of hazelnut spread into the garbage. A tragedy to your taste buds, but there is nothing else you could have done.

If containers like those of Nutella jars had been designed differently, maybe you would not have been left in sorrow wondering if you should have tried harder. Not only can it be a tough play on our emotions, inefficient food packaging is a considerable source of food waste. Nutella is not the only brand guilty of forcing us to waste food—peanut butter, condiments like ketchup and mayonnaise bottles, salsa jars, glass bottles of thick sauces like teriyaki, and even yogurt cups all leave behind dirty containers that often end up either down the sink or in a landfill. 

If you were to add up all the ketchup you’ve thrown away during you whole like from “empty” bottles, how many new bottles could you fill? One? Five? Food waste in landfills is a significant producer of methane, a greenhouse gas 30 times more potent than the infamous carbon dioxide.

Not all packaging favours food waste like the examples above. Yogurt tubes, freezies, and bagged milk allow you to perfectly squeeze out all the contents, popsicles can be sucked until only a compostable wooden stick is left, and butter wrappers perfectly peel off the block when it is cold enough. Trying to decide between a tasty treat and being conscientious of the environment can often require making sacrifices; without our continuous awareness of climate change, however, we might not be around for too long to be able to make these decisions.

It’d just be nice if they made tubed Nutella.


100 Meter Diet

Imagine hardly having to go to the supermarket. Imagine having a variety of healthy food available at your fingertips. Imagine having almost all the food you could ever need growing in the comfort of your own backyard.

Though this exact kind of a life might seem almost imaginary, a woman in Toronto named Julie nourishes herself with her own 4×8 meter vegetable garden for a large portion of the year, a style of living that she calls the 100 Meter Diet. Having spent a large portion of childhood on her grandparent’s farm, Julie became familiar with different kinds of edible plants, their optimal growing conditions, growing seasons, and today still learns from growing plants she is not familiar with. Julie says growing food has always come naturally to her; although it may seem as difficult labour for many, she finds picking fruits and making jam a relaxing part of her everyday life.

Julie grows a variety of foods while ensuring that at least something is always ready to harvest during the summer. For example, she says she can collect a lot of asparagus at the beginning of the summer, but must wait for squash until the end. Preparation for the garden happens year-round, however, with garlic being planted in the fall and starting pepper and tomato seeds indoors as early as mid-February. Julie clarifies, however, that she cannot always be completely independent, as she does not grow too many protein-rich plants like chickpeas, cannot grow certain herbs and spices because of Canada’s climate, and does not have access to animal-based products like eggs and milk, which does lead her to the supermarket for certain foods.

Even as an experienced gardener with an academic background in forestry, Julie subscribes to different magazines such as Small Farms Canada and experiments with different techniques of growing every year. She says to ensure not too many of one thing is planted at the same time, as she mentions a time when she accidentally planted too many radishes and they all went to seed, making it so they could no longer be eaten. If she has an excess of food, she often pickles it in jars, freezes it, makes jam, or shares it with her neighbours. Julie loathes food waste, and keeps her own composter in her backyard which she feeds right back into her crops whenever she can.

Julie’s garden is built from passion, history, and her devotion to sustainability. If you are looking for a way to eat healthier and more locally, starting you own backyard garden – or even participating in a community garden – is an amazing first step.
