1st week long “Volunteer action of cleaning Mljet National Park bays and coves” has ended. From Zagreb’s mountaineering club “Panj” 16 volunteers arrived in our new volunteering center Kulijer on Saturday April 2nd, 2016. During 7 days our volunteers have collected more than 320 garbage bags of mostly small waste. This way we would like to thank our volunteers for their time and effort and we wish to stress out the problem of sea waste that Adriatic encounters. Cleaning of bays and coves is just temporary and not permanent solution. This problem has to be solved at its source.
