In today's throwaway society, it's all too easy to buy goods as and when we need them and simply bin them once they've served their purpose, and a surprising amount of perfectly usable stuff ends up as waste—and it's not just what we can see in the bin either.

When we throw away a product—be it a toy, a T-shirt or a tomato we're wasting more than the product and the money we spent on it, we're wasting all the effort that went into it growing it or mining the materials to make it, manufacturing it, packaging it for sale, and transporting it to the shop or to our door, for example, a cheeseburger has a carbon footprint of around 10 kg CO₂eq. That's 30 times higher than its weight. 98% of a cheeseburger's total carbon impact actually comes from its production. Its waste impact accounts for just 2%. Similarly, despite weighing just io9 grams on average, the waste footprint of a smartphone is more than 500 times higher at a massive 8o kg. I hat s including the waste generated in mining materials to make it, like precious metals, but doesn't even include emissions(排放) generated in the manufacturing process.

In Scotland, 80% of carbon footprint comes from all the goods, materials and services which we produce, use and often throw out after just one use. What's more, around half of those emissions are produced overseas in countries poorer and more polluting than Scotland. Not good news.

There are signs of hope. More and more people are beginning to realize how serious this waste is and to use that knowledge to inform our purchases. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
