Shetland's beaches look beautiful (though tend to be rocky rather than sandy)
and the sea looks free of anything other than the occasional raft of auks floating past
Marine Conservation Society, find out more here. Or your local Park friends group may organise regular clean ups. I pick litter every week as part of my volunteering work with Water of Leith Conservation Trust, who also run regular group cleanups - find out more about volunteering with the trust here.
One of the problems with plastic pollution is that often it looks like food to birds or sea mammals that are hunting and so they take it to their nest to feed to their young. This means that the young birds have their stomachs filled with plastic rather than food and so may starve to death.Not Whale Food specifically campaigns on this aspect of plastic pollution.
There are also many simple ways to reduce your use of plastics, see for example this list from Greenpeace. (However it's important to remember not to replace one problem with another. If you use cloth carrier bags instead of plastic bags you need to be aware that more energy is used in their production so just make sure that you have a few rather than keep buying lots of pretty bags, similarly keep cups are more energy intensive than throwaway cups so you need to keep using your keep cup not get rid of it after you've used it four times just to buy a prettier one.)
You can also commit to not using single use plastics for a month for Plastic Free July.
