Resolution #1: Become a do-it-yourselferGreen resolutions start in the home—and many of these begin in the kitchen. That’s where Ms. Coulter mixes up concoctions for home cleaning supplies, toiletries, bird feeders, and even cat litter. “It’s really easy and super cheap to make your own, and the concoctions work better than store-bought [options], minus the toxic chemicals, fragrances and dyes,” says Coulter. Studies show the average American household uses 40 pounds of chemicals each year to clean their homes, and that chemical compounds from home cleaning products wind up in local streams and rivers. Here’s yet another reason to mix your own: toxic exposure from chemicals inside dwellings is two to five times higher than outdoors.

Resolution #2: Cut down on food waste

Nationally, Canadian homes throw out up to 14 million tons of food annually, estimated to be worth $3 to $5 billion. In Toronto alone, residential food waste exceeds 200 million kilograms per year, most of that edible. Although composting in a municipal bin is a step in the right direction, it still means emissions from trucking and storage in landfill sites. (Not to mention the energy it took to produce the food in the first place.) By eliminating food waste, Canadians can prevent the release of greenhouse gases. One estimate puts the savings at between nine to 15 million tonnes annually.

Resolution #3: Reduce your virtual water footprint

The water we use in our households every day (an average of 100 litres per shower, 20 litres per flush of the toilet) represents only three percent of the water we consume. The remaining 97 percent comes in the form of our virtual water footprint—the amount of water used to produce the products we consume every day, including food. A few examples: 16 000 litres of water is required to produce one kilogram of beef; it takes 140 litres to produce one cup of coffee. Calculating your virtual water footprint and making small changes, such as eating a meat-free meal every week, can help save valuable water resources here and around the globe.

Resolution #4: Get outside 

“There is actual biological value in having experiences with nature, value that is measurable and quantifiable,” writes David Suzuki. He references a recent British study showing the bigger and more biological diverse a park was, the greater the sense of health and well-being experienced by participants who visited it. “General health, mental fatigue and physical injury all recover faster when patients have access to natural areas.” The Suzuki Foundation’s Coulter suggests not only getting outside more often, but also doing it closer to home. After all, studies indicate aviation accounts for 4 to 9 percent of total climate change from human activity.
