Is your organic farmer "sustainable"?

So, is your organic farmer 'sustainable'?  Does he practise sustainable agriculture, or is he the organic version of the commercial industrialised farmer? 

Here's an example of how we practise sustainability:

This is a filtration pond.  Plants are used to absorb the nutrients in waste water from the fish ponds and from washing the rebans.  From the pond, the water flows out into a bacterial filter to further break down the pollutants.

From the bacterial filter, a long narrow winding stream further filters the water using water plants. 

Alongside, water loving plants such as bananas, misai kucing, etc. will absorb all nutrients that seep into the surrounding soil. 

 We try to reduce our foot print as best as we can.

So, is your organic farmer 'sustainable' or is it just business for him?
