There is the ‘evidence’ of one side behind the global scam which translates into money for those milking the issue. There is reaction against this, which translates into denying anything happening at all.
There is anecdotal evidence, notoriously fragmented, even if there is no agenda. They mention the Mersey – I’m not on the Mersey but near to the Manchester Canal – when we go for drives, we see many rivers, from the Dee to the Mersey to those further north and south and I certainly do not see a plastic strewn wasteland of plastic.
Interesting that the leftist Independent has this:
Plastics in oceans are mounting, but evidence on harm is surprisingly weak. Unsupported speculation can lead to scarce resources being misdirected when they could be better spent on other environmental issues
That might be getting closer to it. The nature of rivers is that they flow in and out at amazing speed in some cases – the Mersey can be around 7 knots at full flow and in places – 10 knots. [Therefore any sailboat needs to be capable of more than that.]
Waste in the water is going to accumulate near banks, it’s not going to hang about in the middle of the flow. Having said that, there’s little doubt that people are pigs, not even as hygienic as pigs and it’s interesting that the worst areas for human garbage are leftist – places where Labour or the Dems are in control. There’s more civic pride in more salubrious areas.
So there are half truths – the left makes a huge noise about pollution but causes most of it and around these parts, they’re right pigs; the right does not say much but nonetheless has this civic pride – I’ll always look for a bin to put the rubbish or else take it home. My parents used this mulcher device.
Against that, I don’t see all that much rubbish strewn on footpaths around here – sometimes, yes and it’s dealt with, meaning the miscreants are. The wind takes most of it and it can build up in corners.
