Ibyuma byabo babihanze mu kirere, mu isanzure bamenya ibibera kuri Mars no ku kwezi kurusha ibibera mu Nyanja zibakikije kandi zibafatiye runini.

UNESCO ivuga ko abahanga bazi 20% gusa y’ibinyabuzima n’ibindi biba mu ndiba y’inyanja z’isi zose.

Ni umubare muto ariko nanone urahagije kugira ngo abantu bamenye kandi bemere ko inyanja ari umubyeyi ufitiye abana be( abatuye isi) akamaro kanini.

Bimwe mu bikoresho inyanja zikoresha mu rwego rwo kugirira abantu akamaro ni uruhuri rw’ibinyabuzima biba hasi cyane mu Nyanja byitwa Les Coreaux.

Nta jambo ry’Ikinyarwanda abo mu Nteko y’Umuco n’ururimi babihaye kuko bitaba no mu Rwanda.

Akamaro k’ibi binyabuzima karagutse kuko bifasha mu kuyungurura umwuka duhumeka, bikawukuramo ibibi biwurimo ariko byo bikeneye, ubundi tukawuhumeka ucyeye.

Kwangirika kw’ibi binyabuzima kuvuze kwiyongera k’umwuka uhumanya, ugira ingaruka ku binyabuzima bihumeka byose cyane cyane umuntu.

Inyanja kandi ni isoko y’ibiribwa bigaburira miliyari eshatu muri miliyari zirindwi zirenga z’abatuye Isi.

Ibikoresho bya pulasitiki, n’ibindi binyabutabire mwenemuntu ata mu Nyanja byica amafi n’ibindi binyabuzima yari buzakenere ngo aramuke.

Ibi bizaba biterenze umwaka wa 2050.

Raporo y’abahanga b’Umuryango w’Abibumbye ivuga ko miterere y’ikibazo cy’iyangirika ry’ibinyabuzima bituye inyanja ivuga ko bikwiye ko Leta z’ibihugu bituriye inyanja kandi byifite zagombye kongera ingengo y’imari ishyirwa mu bushakashatsi ku binyabuzima byo mu Nyanja.

Ibinyabuzima byo mu nyanja bizwi ntibirenze 20%

Indi raporo yasohotse mu mwaka wa 2020 yiswe Global Ocean Science Report yavuze ko Leta zishyira 1.7% by’ingengo y’imari yabyo mu bushakashatsi mu binyabuzima biba mu Nyanja.

Ubufatanye mu bushakashatsi mu by’inyanja ni ngombwa kandi hari n’ibihugu byabibonye kare birihuza.

Byarihuje bikora ihuriro ryo gucungira hafi no kuburirana igihe cyose hagiye kuba umwuzure uterwa n’iruka ry’ibirunga witwa Tsunami.
