Notes:
Lichens are actually two types of organisms living together, a fungus and an alga. The fungus makes the body that protects the alga and the alga provides the food for the fungus. Lichens can be used as air pollution indicators, especially of the concentration of Sulphur dioxide in the atmosphere.

Notes:
Ecological sanitation is a sustainable system for handling human excreta, using dry composting toilets. This is a practical, hygienic, efficient and cost-effective solution to human waste disposal. With this composting method, human excreta can be recycled into a resource (as natural fertiliser), which reduces the need for chemical fertilisers.

Notes:
The Great Dividing Range, home to a UNESCO World Heritage Site – the Wet Tropics of Queensland, exhibits an exceptional display of natural beauty, diverse species, and is soaked in evolutionary history. This region preserves the ancient Gondwanan forest of 50-100 million years ago, and is significant in deciphering the evolution of Australian flora and fauna. The range hosts over 400 threatened or rare species and indigenous communities have resided here for over 5,000 years. The highest Australian waterfall, Wallaman Falls, the 13 primary river systems, and multiple national parks are also part of this geography.

Notes:
K’gari, also known as Fraser Island, is recognized globally as the largest sand island. Located in Queensland, Australia, this World Heritage-listed island covers a vast expanse of 120 kilometers. Further adding to its ecological significance, it harbors varied ecosystems ranging from rainforests to perched freshwater lakes. Notably, it serves as a habitat for a pure breed of dingoes and is home to Boomanjin Lake, the world’s largest perched lake. The island carries a historic and cultural resonance as it was once associated with the Butchulla people and used as an Allied training base during World War II.
