Read the text

The journey of our “stuff” begins long before it arrives in our homes. The final product is a result of many processes: harvesting, processing, dyeing, building, mixing, printing, shipping, etc. At every step of the way is the potential for environmental degradation, pollution, human rights issues, health risks, and more.

If every human consumed the resources of an average American, the Earth would only be able to sustain 1.4 billion people. As disheartening as this may seem, we are major contributors to the problem, we are both responsible for and capable of generating a solution.

Of course, the most effective way to reduce waste, environmental destruction and pollution (not to mention, save money!) is to simply buy less. Even the most sustainable, locally sourced, fair trade item loses out when faced with the alternative of not buying anything at all. Although we are grateful for the opportunity to purchase these more ethical products at a time of need, the reality is that if we don’t need it, we shouldn’t buy it at all.

Technology has made it easier and faster to the consumer. However, it has also given us the responsibility of using our access to information to make more thoughtful choices. Realistically, the purchase of a single sustainable product won’t make much of a dent in the overall scheme of the world’s material consumption. However, the importance of the act is undeniable.

We must be conscious that every decision we make has an effect on the health of our ecosystems and ourselves. By voting for quality over quantity, by acting as informed consumers and demanding smarter products, we are all advocates for a sustainable tomorrow. And in this, we will find a greater connection to ourselves, our communities, and the things we call our own.
