the yaranga uses fewer materials/resources/wood to construct than a modern city house; the yaranga is made of entirely renewable materials, (the city house is not); all yaranga materials are biodegradable/naturally recyclable, (some city house materials are not); the city house has associated infrastructure roads/utility supplies etc, the yaranga does not; production of concrete used in city house produces waste and chemical pollution; the yaranga is mobile so no permanent destruction of habitat, (city house is not); yaranga has smaller size; yaranga is made from local materials, therefore less energy used in transport; yaranga is made from local materials that are used sustainably; yaranga may be better insulated/less heat loss;

Marking guidance:

Do not accept only 'yaranga has a smaller ecological footprint'.
Do not accept only 'yaranga made of wood/local/natural materials'.
Do not accept only 'modern city houses use concrete/bricks/ man-made materials'.
For credit a reason much be given to why the materials used are more/less sustainable.
