Seeing what the linear economy is and why it’s no longer working

Recognizing why natural resources (fossil fuels, minerals, food, water) are getting harder and harder to come by

Acknowledging that the impact of the linear economy is now catching up with us

The earth has been around for 4½ billion years. We know that living systems have been around for most of that time (3½ billion years) and will probably be around for a few billion more. We humans, on the other hand, have only been part of these living systems for around 200,000 years — a fraction of that time. Yet even in that small period, humans have managed to disrupt every living system on the planet.

In nature, there is no landfill, no concept of waste. Everything in nature becomes a material flow (a natural resource) for something else — either food, nutrients, or energy. Everything we have is right here on the planet. The only incoming resource we have is sunlight (and maybe the occasional asteroid or two).

All living systems on Earth (except humans) are able to live in harmony with that balance. Species are born, they live, they die, and they feed their nutrients back into the soil safely. The sun provides warmth and energy, and it all just works well, in an elegant, closed loop — a circular approach to resources.

We humans follow quite a different approach, one where we take, make, use, and, eventually, waste — or take-make-waste. We extract natural resources until they’re exhausted; we package products in containers that cannot be reused; and we design products that can’t be repaired so that people are forced to throw them away and buy new ones. We ignore the free energy from the sun and instead burn the last bits of energy in the ground left by the death of the dinosaurs. It doesn’t work — all the linear approach does is slowly convert our human resources into waste.

Every time we humans follow this linear approach, we’re slowly chipping away at our limited and finite supply of natural resources and leaving toxic waste in its place. We simply can’t keep going like this forever, and the worst consequences of our irresponsible actions haven’t even caught up with us yet.

Take, for example, the fashion industry. Each year, millions of tons of raw materials are harvested from the earth. We use massive amounts of fossil fuels to power machines to manufacture those materials into clothing and then to ship them around to stores across the planet, which fills the atmosphere with greenhouse gas emissions. As if that weren’t bad enough, after wearing these clothes, we decide at some point (one year, three years, ten years), to throw them away and three-quarters then end up in a landfill. (See Figure 2-1.)

FIGURE 2-1: The typical approach to making clothing is the linear model.

Because we’ve been doing it this way for so long, we fail to see the opportunities to improve this linear process. Imagine, instead, that we took the approach outlined in Table 2-1.

Seen in this light, the linear approach isn’t that great, is it? A circular-economy approach seeks to take those linear approaches to materials, energy, and reuse and bend them into a more circular approach — an approach that mimics what happens regularly in nature.

TABLE 2-1 Prescription for the Future

Replace This	With This
Extracting natural resources	Using recycled or bio-based materials
Packaging in single-use plastic	Packaging in reusable packaging or none at all
Burning fossil fuels for energy	Using clean, renewable energy
Shipping products around the planet	Creating local networks of manufacturing
Making products that become outdated	Designing durable products that can be adapted or updated
Tossing products into a landfill	Designing products to be repairable, biodegradable, or recyclable

In this chapter, we explore how this linear approach isn’t exactly working for the planet and why we humans need to drastically change how we produce our food, products, packaging, and everything else in order to be more circular — like all the other living things in nature.
