An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non living or abiotic environment. Within an ecosystem, any change of one part affects the other components.
It may seem strange to think of a home as an ecosystem but modern housing is a relatively new way of viewing the home environment. Previously, people instinctively worked with their local environment by using local material and housing design which was appropriate for the local conditions; for example traditional tropical houses were raised platform housing made of wood whilst earth and turf covered houses were more common in cold and dry climates. In fact the word ecosystem comes from a combination of the word ecology and system with ecology rooted in the Greek word Oikos, meaning house.
When thinking of a house as an ecosytem we must consider it’s inputs and outputs; and how these are maintained to ensure a delicate balance through dynamic equilibrium. Inputs include electricity, light and water which are directly or indirectly derived from the Sun and the planets water cycle. Outputs include water, heat and waste.
Often, in modern housing, our outputs are polluted, the external ecosystem can help us with this but again there must be balance, for example waste materials can take much longer to break down then they do to be produced which is one of the strains we are putting on the planet. However by minimising our inputs, or by choosing sustainable sources we can minimise the affects from our home ecosystem.
