Good job bringing this to light. People won't realise how huge the problem is and municipalities are woefully ill equipped to...
Agreed; mining can never be sustainable, but then how do you get the metals to make all the things you need in the course of...
Very good piece.
Folk remedies, which for long used moulds and fungi for patching up wounds, have been discovered to have a scientific basis. Researchers at the British Textile Technology Group in Manchester hope to develop fungus-based surgical dressings to accelerate wound healing.
Fungi contain chitin and chitosan in their cell walls rendering it the special property of wound healing. They attract fibroblasts -- cells which play a key role in wound healing -- anchoring them and helping collagen scar tissue formation. Chitosan when oxidised, produces hydrogen peroxide activating white blood cells and keeping infection at bay.
The lead researcher, Paul Hamlyn has patented processes for growing the fungi in bioreactors, cleaning them and developing them into surgical dressings. For deep wounds he has produced absorbent gauze, and for superficial wounds absorbent sheets.
