. SCIENCE & TECH . Industrial Ecology

The most interesting thing about an ecosystem, is that all matter and energy is cycled and used continuously. It other words, it is renewable. Imagine if all human activities would be like that... Pollution would be minimal, one company's waste would be another company's building material or fuel. This is what is called industrial ecology. It would be cool as well, if instead of throwing out things that are not safely biodegradable, people could just bring them back to the stores they bought them at and the companies that manufactured them would be in charge of recycling the product, in what the famous architect William McDonough coined as a Cradle to Cradle philosophy (check out the book, its really interesting!).
