Incidents of litter and flytipping have increased by as much as 86 per cent in some parts of Wales during the past year.
As part of our In Focus series, our reporter Hannah Thomas has been taking a look at how litter has been causing problems in our countryside.
Merthyr Tydfil Council says it is cleaning up at least 10 separate sites every day.
Litter costs the taxpayer in Merthyr Tydfil alone more than fifty thousand pounds a year to clear up.
And nearby, national park wardens in the Brecon Beacons, say the dumping of rubbish has to stop.
People bring food out to eat for example for a picnic or a barbecue and they don't think that they then need to take it back with them. And the reason people go to these places for their picnics or barbecue is because they're nice places and obviously the more rubbish that's left there the less that's the case.
Elsewhere, Merthyr Angling Club has just won a Green Flag award for its efforts in collecting litter at a local fishing spot.
The groups says it is coming across more instances of littering the more people venture into the countryside.
Later in the series, In Focus will be looking at how litter affects our towns and cities and coastal communities.
