The world is at a crossroads. With the effects of climate change, resource depletion, and environmental degradation becoming increasingly evident, the design of products, buildings, and systems must evolve to address these challenges. The traditional linear economy, characterized by a "take-make-dispose" mentality, has resulted in overconsumption of natural resources, excessive waste, and profound ecological impacts. As a response, sustainable design offers an alternative that minimizes harm to the environment, maximizes resource efficiency, and ultimately promotes a healthier planet. Sustainable design is not just a trend or a passing phase. It is a critical response to the urgent need for a future that balances human needs with ecological integrity. Whether through reducing energy consumption, using renewable materials, or ensuring waste is minimized or repurposed, sustainable design practices aim to create long-term solutions to the environmental issues we face.
