Consuming Manly beach

Beach full of take-away garbage today. Beachbuggy racing up and down for no good reason, filling the beach with petrol fumes. Lately they even 'exercise' their motor-boat on prime beach days, generously socialising the petrol pollution with all the sun-seekers stretched out on ground level. Additionally, thick clouds of garbage and sewage in the form of flies, drill aggressively into all orifices.
Commercial installations spreading all over the beach 'real estate', institutions and operators spilling their 'customers' on the in-between spaces. Balmoral has a 'no commercial activities' beach!
The red tide hovers at a distance, ready to nourish the unthinkable.
