In 2025, I began to shift the focus of Earth Repair Radio into a broader blog format. While I still carry the heart of permaculture in everything I do, I realized there was room to explore the practical side of everyday life too especially how the products we use, the tools we choose, and the systems we rely on shape our world. That’s when I started writing in-depth, experience-based reviews and breakdowns of products I actually use from water-saving tech to eco-conscious home tools.
