Although the number of illegal wild dumpsites has dropped significantly since the first cleaning campaign eight years ago, there is still plenty of work to be done, explain the organizers. "In this year's campaign, we managed to document one third of wild dumps; there are about 10,000 dumps in nature or, to make it easier to imagine – 92 Olympic swimming pools full of waste," describes Katja Sreš from the Ecologists Without Borders.

In addition to wild landfills, the organisers also want to get rid of waste scattered around – often along river banks and on the seashore.

All information about the gathering points and the timeline of the campaign is published on the www.ocistimo.si website. When the waste is collected, utility companies will pick them up, and then it is time for the next step, say ecologists – to prevent the generation of new waste.

"To buy fewer, better-quality things, then also fix and reuse them, or exchange for something else. One of the simplest steps is to make a decision and bring your our own bag to the store from 16th September onwards, so that we do not use plastic bags," advises Katja Sreš.

Only with changes in the way we act will this action truly be the last.
