Human Intervention at Tumbi Wetlands Bushcare 
What is meant by a "clean green project"?
This can include any activity or project that makes more efficient use of natural resources, or reduces the demands you make on them.
e.g. a garden with a low water requirement can save water or
a compost heap (or worm farm as shown) that can recycle some of your food waste.

This will make less demand on landfill sites and reduce the transportation cost for waste disposal,
as well as giving you a great soil conditioner.
