I ka makahiki 2050, aia ma kahi o 12 biliona toni o ka ʻōpala palaka ma ka honua

Ua hana ke kanaka i 8.3 biliona toni o ka plastic.I ka makahiki 2050, aia ma kahi o 12 biliona toni o ka ʻōpala palaka ma ka honua.

Wahi a kahi noiʻi ma ka Journal Progress in Science, mai ka makahiki 1950 mai, ua hana ʻia he 8.3 biliona tons plastics e nā kānaka, ʻo ka hapa nui o ia mau mea i lilo i ʻōpala, ʻaʻole hiki ke nānā ʻole ʻia no ka mea ua waiho ʻia i loko o nā ʻōpala a i hoʻopuehu ʻia paha i loko o ke kūlohelohe. kaiapuni.

ʻO ka hui, i alakaʻi ʻia e nā mea noiʻi mai ke Kulanui o Georgia, ke Kulanui o Kaleponi, Santa Barbara a me ka ʻAhahui Hoʻonaʻauao ʻĀpana, ua nānā mua i ka hana, hoʻohana a me ka hopena hope loa o nā huahana plastik āpau a puni ka honua.Ua hōʻiliʻili nā mea noiʻi i ka ʻikepili helu e pili ana i ka hana ʻana i nā resins ʻoihana like ʻole, nā fibers a me nā mea hoʻohui, a hoʻohui i ka ʻikepili e like me ke ʻano a me ka hoʻohana ʻana o nā huahana.

Ke komo nei nā miliona o ka plastic i ka moana i kēlā me kēia makahiki, e hoʻohaumia ana i ke kai, e hoʻopuehu ana i nā kahakai a me ka hoʻoweliweli ʻana i nā holoholona hihiu.Ua loaʻa nā ʻāpana palaki i loko o ka lepo, i ka lewa a me nā wahi mamao loa o ka Honua, e like me Antarctica.ʻAi ʻia nā microplastics e nā iʻa a me nā mea kai ʻē aʻe, kahi e komo ai lākou i ke kaulahao meaʻai.

Hōʻike ka ʻikepili he 2 miliona tons ka hana ʻana i ka honua i ka makahiki 1950 a ua hoʻonui ʻia i 400 miliona tons ma 2015, ʻoi aku ia ma mua o nā mea i hana ʻia e ke kanaka koe wale nō ka sima a me ke kila.

ʻO 9% wale nō o nā huahana palaka ʻōpala i hana hou ʻia, 12% ʻē aʻe i puhi ʻia, a ʻo ke koena 79% e kanu hohonu ʻia i loko o nā pae ʻāina a i hōʻiliʻili ʻia i loko o ke kaiapuni kūlohelohe.ʻAʻole hōʻike ka wikiwiki o ka hana plastic i nā hōʻailona o ka lohi.Wahi a nā ʻano o kēia manawa, aia ma kahi o 12 biliona tons o ka ʻōpala palaka ma ka honua i ka makahiki 2050.

Ua ʻike ka hui ʻaʻohe hopena pōkā kālā e hōʻemi ai i ka pollution plastik honua. Akā, pono ka hoʻololi ʻana ma ke kaulahao lako holoʻokoʻa, ʻōlelo lākou, mai ka hana ʻana i nā plastics, i ka hoʻohana mua ʻana (i kapa ʻia ʻo upstream) a ma hope o ka hoʻohana ʻana (recycling. a me ka hoʻohana hou ʻana) e hoʻōki i ka laha ʻana o ka palaka palaka i loko o ke kaiapuni.
