@Ineedwinenow Sungai watch is the bali org, they put special barriers called 'trash booms' in the rivers, to stop the rubbish going into the ocean, then they collect the trash by hand and sort it to dispose or recycle, which is a huge job. I like the idea of collecting it before it gets to the ocean and support groups like sungai for that reason. Obviously stopping people throwing trash away and reducing plastic are also important.
@MrsFinkelstein one of our kids got that same thing somewhere, didn't produce any wildflowers but that could of been our fault- or the cats digging!
