Interesting thread. It does seem there are many different policies about how to deal with plastic, but it seems to me that the sheer scale of the problem is an issue. I appreciate that action has to start somewhere, so any local or national action has to be a step forward, but I would think there needs to be international pressure.
I live in eastern europe (about 10 years now), and it is clear there is a major attitude difference here: rubbish can be and is dumped anywhere – there is no education or information about the damage this causes. Although countries like the UK may be taking steps to curtail single-use plastic, such as PET bottles, the manufacturers are increasing their use of them in other countries. Drinkable water is a luxury here, so literally tons of bottled water is sold every day – all in PET bottles. Companies churn out cola, sticky 'fruit' drinks, in fact anything which will go into a bottle, goes into a PET bottle – and its no exaggeration to say most of these end up thrown to the side of the road here. (Rubbish collection is also almost unknown).
We have about 5 acres of land in a remote, rural part of the country, close to a small village of about 800 people. The only 'industry' around here is illegally cutting oak and ash in the State Forest, for shipping to Austria and Hungary. When we bought the land; we spent about a week collecting and removing plastic rubbish left on the land by these wood thieves. About 75% was old PET bottles. We eventually collected 5 full loads in a 1-ton trailer. (I don't have space to tell the story of the trouble it took to get rid of them).
Another point I would like to make: has anyone ever looked at the production of childrens toys? – almost all plastic these days. Not a bad thing that Toys'R Us went bust.
OK – rant over – just wanted to make a point about the scale of the problem
