What is interesting, even more than Government directives, is the local movements for change. Here in Falmouth, Cornwall, UK there have been many groups making efforts to combat plastic waste and now a group called 'Plastic Free Falmouth' is wanting to bring our local efforts into harmony. After all, we truly are stronger together and co-ordinating activities seems like a wise move to me.
What can we as individuals do in the meantime? Well, one thing is we can get ourselves a litter picker and get out there clearing up the crap. I got mine off the internet (link below) its a brilliant piece of kit and saves having to grovel in all the rubbish other sapiens have left behind. Its actually quite good fun, gets you talking with others and the kids love it too. But best of all is the warm fuzzy feeling that you have made a difference. Because of you an animal might not have to die a horrible painful death. If that's not an incentive, I don't know what is!
Just to add to the above.. you can get cheaper versions of litter pickers but I really wouldn't bother. This one works well and I've shifted A LOT of rubbish with it - and it's still working. Another example of you get what you pay for!
Let's all do our little bit because all our little bits add up to a whole lot more. :-)
