Harbor cleaning activity was conducted by PN personnel and banners and posters were displayed and leaflets about steps to restore ecosystem were distributed in PN units and residential areas. A webinar under auspices of National Institute of Maritime Affairs is also organized to highlight significance of preservation and restoration of Marine Ecosystem. In addition to the awareness campaign, practical steps like mangroves and tree plantation campaigns are already underway. In this regard, over 7 M mangroves along the coast and over 2 M trees in different parts of the country have been planted till to date in line with Govt's Vision of 'Plant for Pakistan'.
