Zuva reMiorivhi reNyika rine chinangwa chezvisikwa. Nekubatsirwa kwezororo rino, vatsigiri varo vaida kutora pfungwa dzevanhu vose venyika kusvika mumamiriro ezvinhu muNyika yeNyika uye nekuchengetedzwa kwevagari vayo. Mushure mezvose, gungwa igadziriro yakasiyana-siyana yezvinhu zvakatsigira hutano hwehupenyu. Asi kupindira kwevanhu kwakatungamirira pakuziva kuti ichi chiyero chinoputswa nguva dzose: gore roga roga muNyika yeNyika, zvinenge zvuru zvemarudzi ehupenyu hwemvura zvinopera.
Isu tose tinoziva kuti nhasi dambudziko rekusvibiswa kwemukati nemafuta ekupisa zvinowedzera. Mukuwedzera, uwandu uye huwandu hwemvura yekunwa paNyika huri kuwedzera. Kuvhara kwegungwa nemakungwa, kuparadzwa kusingadzorwi kwezvombo zvegungwa, zvishoma nezvishoma zvinotungamirira kuparadzwa kwezvose zvipenyu zvegungwa. Masayendisiti anofanotaura kuti gore ra2015, asidi yemvura ye-oceanic inogona kuwedzera ne 150%, iyo inotungamirira kurufu rwehupenyu hwose hwemvura.
Gore negore musi waJune 8, kumativi ose enyika, zviito zvakasiyana-siyana zvezvakatipoteredza zvakarongeka, nekubatsirwa kwavanoitwa nevarongeri avo kuedza kuudza vanhu vose kudiwa kwekudzivirira nyika yeWorld Ocean. Pazuva rino, zviratidzo zvakasiyana-siyana, mhemberero, misinari, rallies, hurukuro pamusoro pegungwa rinowanikwa.
Gore roga roga, kupemberera kweZuva reNyika yeOceans rinoitwa pasi pemitoti yakasiyana-siyana. Somuenzaniso, muna 2015 yakanzwika se "Marita ane utano, nyika ine utano".
Nokudaro, kupemberera zuva reHorld Ocean, vanhu vane mukana wekuchengeta zvisikwa, upenyu hwemvura nemhuka. Uye kunetseka kwakadaro kune vagari venyika yeWorld Ocean kuchadzivirira kuparadzwa kwemhuka zhinji nemiti, izvo zvichabatsira kuchinja hupenyu hwedu munguva refu.
