Pick up something you use every day: a phone, a T-shirt, a hockey stick. Each one began as resources dug, grown or pumped from the ground, was made in a factory (often on another continent), travelled thousands of kilometres to reach you, and will end up recycled, reused or in a landfill. Every stage uses energy and resources and affects people and places. Sustainable development asks how we can keep meeting people's needs, including jobs and the products we rely on, without wearing out the environment and communities that make them possible. This final lesson pulls the whole unit together.
What is sustainable development?
The best-known definition comes from the United Nations' Brundtland Commission in 1987: development that meets the needs of people today without compromising the ability of future generations to meet their own needs. It is usually pictured as three overlapping pillars: a healthy environment, a fair and healthy society, and a strong economy. A choice is truly sustainable only where all three overlap. Many Indigenous perspectives express a similar idea in their own terms, such as the Haudenosaunee principle of considering the effects of decisions seven generations ahead (Unit 2). Real decisions involve trade-offs: a new mine may help the economy and local jobs while harming a river, so the goal is to find options that do well on all three pillars, not just one.
| Model or approach | Main idea | Canadian example |
|---|---|---|
| Three pillars | Judge every decision by its environmental, social and economic effects together | Environmental assessments of mines and pipelines weigh all three |
| Circular economy | Replace the linear take, make, waste model with a loop: design products to last, reuse, repair, remanufacture and recycle, so materials stay in use | Refurbished phones; recovering metals from old batteries and electronics |
| Certification and eco-labels | Independent groups check that products meet environmental and social standards, so buyers can choose | Forest Stewardship Council (FSC) labels on wood and paper; Marine Stewardship Council (MSC) labels on seafood |
| Extended producer responsibility | The company that makes or sells a product pays for collecting and recycling it, which rewards less packaging and easier recycling | Ontario has shifted its Blue Box program and electronics recycling to producers |
| Ecosystem-based management | Manage the whole ecosystem, and the communities in it, rather than one resource at a time | The Great Bear Rainforest on the BC coast |
| Indigenous-led conservation | Indigenous governments protect and manage lands and waters using their own laws and knowledge | Indigenous Protected and Conserved Areas and Guardians programs (Unit 2) |
Strategies and how well they work
| Strategy | Who | How effective, and from whose view? |
|---|---|---|
| Fishing quotas and the 1992 cod moratorium | Federal government (Fisheries and Oceans Canada) | Stopped the collapse, but northern cod recovered slowly over decades; fishing communities paid a huge price, and many fishers felt their local knowledge was ignored. Scientists still debate how fast catches should rise. |
| Great Bear Rainforest agreements (completed 2016) | BC government, coastal First Nations, forest companies and environmental groups | About 85 percent of the region's forest is protected from logging; the rest is logged under strict ecosystem-based rules. Widely praised as a model of cooperation; some groups argue more old-growth forest still needs protection. |
| Forest certification (FSC and others) | Forest companies, checked by independent certifiers | Canada has more independently certified forest than any other country. Supporters say it raises standards; critics say certification has not stopped declines in some caribou herds. |
| Phasing out coal power in Ontario (completed 2014) | Ontario government and Ontario Power Generation | Very effective: emissions from electricity fell sharply and smog days in the province dropped. Electricity prices rose, partly because of the cost of new generation. |
| Oil sands reclamation rules | Alberta government and oil sands companies | Companies must reclaim mined land, but reclamation is slow, and only a small area has been officially certified as reclaimed so far. Tailings ponds remain a major concern for downstream First Nations such as the Athabasca Chipewyan. |
| Towards Sustainable Mining (since 2004) | Mining Association of Canada and its member companies | Member mines report publicly on community relations, tailings, energy and biodiversity. Supporters see real improvement; critics note it is voluntary and run by the industry itself. |
Who influences resource decisions?
| Group | How it influences sustainable development | Example |
|---|---|---|
| Governments (federal, provincial, municipal, Indigenous) | Make laws, set quotas and emission rules, issue permits, create parks, run environmental assessments | Fisheries quotas; Ontario's coal phase-out; Indigenous Protected and Conserved Areas |
| Industries | Choose extraction methods, invest in cleaner technology, seek certification, sign benefit agreements | Electric equipment in mines; FSC-certified forests; carbon capture |
| Advocacy groups | Research, campaign, run boycotts or lawsuits, and help negotiate agreements | Environmental groups that helped negotiate the Great Bear Rainforest agreements; groups pushing for stronger tailings rules |
| Local community organizations | Monitor and restore local environments and give residents a voice | Ontario's conservation authorities and watershed groups; community tree-planting and shoreline clean-ups |
| Individuals | Buy, reuse, repair and recycle; vote; comment on proposed projects; choose careers | Keeping a phone longer; buying certified products; speaking at a public consultation |
The life cycle of everyday products
| Stage | Smartphone | Cotton T-shirt | Composite hockey stick |
|---|---|---|---|
| Resources | Dozens of elements: cobalt (much of it from the Democratic Republic of the Congo, where child labour in some mines is a concern), lithium, copper, gold, rare earths | Cotton, a thirsty crop often grown with lots of pesticide; one widely cited estimate is about 2,700 litres of water for one T-shirt | Carbon fibre and resin, made from fossil fuels (older sticks were wood, such as ash or birch) |
| Production | Chips and screens made and phones assembled mostly in Asia, using a lot of electricity | Spun, dyed and sewn mostly in Asian countries such as Bangladesh, often for low wages; dyes can pollute rivers | Layers moulded under heat and pressure in factories, many of them overseas |
| Distribution | Flown or shipped worldwide | Shipped in containers across oceans, then trucked to stores | Shipped to Canada and sold in sports stores |
| Use | Charging uses electricity; often replaced after a few years | Washing and drying use energy and water and shed microfibres | Composite sticks can break after a season or less of hard play |
| End of life | E-waste: valuable metals can be recovered, but many phones sit in drawers or end up in landfills | Most clothing is thrown out; only a small share is resold or recycled | Hard to recycle because the fibres and resin are fused together; a few programs grind them into new products |
Six questions to ask about any product
1. What resources is it made from, and where were they extracted? 2. Who made it, and under what working conditions? 3. How far did it travel to reach you? 4. How much energy and water does it use while you own it? 5. How long will it last, and can it be repaired? 6. What happens to it at the end: reuse, recycling or landfill? The most sustainable product is often the one you already own and keep using.
