The return of warmer weather in recent weeks has lured many Adelaideans back to the coast – ready to embrace the beach culture that we so love in summer. If you were among the walkers or swimmers, perhaps you too have been appalled by the colour of the water – a huge unappealing brown slug hugging our favourite beaches.

The cause is a cocktail of silt and other pollutants that has been pouring out of the creeks and many stormwater drains that empty onto the coast for decades. The incoming and outgoing tides mix and spread this pollution – but only a bit. Water in Gulf St Vincent does not move extensively – it basically sloshes in and out (up and down the Gulf), so the pollution radiates slowly away from its source.

In still conditions, the silt settles out, and water quality can be pretty clear. When windy weather hits, the silt is remobilised – stirred up – and the water becomes brown once again.

Depressingly, this layer of gunge is now a permanent feature of the Adelaide metropolitan coast.

But the story is more complicated…

Plastics - what can’t you avoid or still struggle with finding an alternative? . “Dried Dog food that’s not overly expensive (but recently found a brand that is meant to be home compostable packaging but will have to see if it passes my dog’s taste test!), potato and corn crisps (there seems to be alternative to all other snack packaging except for these) and CDs – I have always loved the joy of purchasing a new music CD and most come in plastic hard or paperboard plastic covered. Those three all have alternatives, but they are my naughty weaknesses. . The main struggle for me, as a someone who is gluten AND lactose intolerant AND travels to remote places, is sometimes I have to eat a lot of rice or just accept the plastic until I find a way to get the venue or place to change. Usually I take my own packaging with me and then bring it home to recycle, for example when I am home my bread comes in paper or reusable bags, but travelling I will take with me gluten free bread in plastic sealed bags.” .

 Continuing on with our chat with Featured speaker Sarah-Jo Lobwein and the work she does in regards to single use plastics #swapforthesea . 1. Plastics - what have become your favourite swap items? . “There are technological advancements and inventions, (or rediscoveries of what society used before we became addicted to plastic), all the time that amaze me – straws made out of wheat for example, and consumable soft bio plastic packaging of pasta made out of algae that we can just throw into boiling water etc. . But my favourites are the every day items – reusable, take your own or compostable straws, cutlery, takeaway containers, coffee cups, water bottles, shopping bags, paper bin bags and produce bags because they are so easy and accessible –humans were using them before plastic was invented or became prolific. The ones that reduce waste in general such reusable or not using an item at all is the best solution (such as not using a straw), and then compostable such as paper or bamboo. . Personally I can’t believe how empty my bins are once I phased out most plastics – I use the paper sandwich/ mushroom veggie bags or paper retail shopping bags for my bin and wash out the bin if it gets dirty (and there are businesses now that can come clean your bins!) - there is always an alternative.” . . . . . . . . #waronwaste #waste #saynotoplastics #refuse #recycle #reuse #repurpose #upcycle #protectourgulf #saveouroceans #gogreen #nature #conservation #climateaction #marinedebris #beachcleanup #bethechange #adelaide #fogsv #friendsofgulfstvincent
