Sustainability could be defined as the ability of something to sustain itself. Living sustainably is about living within the means of our natural systems, the environment and ensuring that our lifestyles don't harm other people, societies and cultures.

We need to look at all the resources we bring into our lives and what we throw away.

There are actually three elements involved; aquaculture (growing fish) hydroponic (growing soilless plants) and bacteria. Enlarge the diagram to see how it works.
