Lero, aliyense amagwiritsa ntchito zinthu zapulasitiki. Tsiku lililonse, anthu amakumana ndi zikwama, mabotolo, maphukusi, zotengera ndi zinyalala zina zomwe zimawononga dziko lapansi. Ziri zovuta kulingalira, koma magawo asanu okha mwa magawo onsewo ndi omwe amatha kusinthidwa. Kwa zaka 10 zapitazi, kupanga zinthu zapulasitiki kudafika pachimake.

Mitundu ya kuipitsa

Opanga pulasitiki amakakamiza anthu kuti azigwiritsa ntchito zomwe amapanga kamodzi, pambuyo pake ayenera kuzitaya. Zotsatira zake, kuchuluka kwa zinthu zapulasitiki kumawonjezeka tsiku lililonse. Zotsatira zake, kuipitsa madzi kumalowa m'madzi (nyanja, malo osungira, mitsinje, nyanja), nthaka ndi pulasitiki zimafalikira padziko lonse lapansi.

Ngati m'zaka 100 zapitazi kuchuluka kwa pulasitiki kunali kofanana ndi kotayako zinyalala zolimba zapakhomo, ndiye patadutsa zaka makumi angapo chiwerengerocho chinawonjezeka mpaka 12%. Vutoli ndi lapadziko lonse lapansi ndipo silinganyalanyazidwe. Kulephera kwa pulasitiki yowola kumapangitsa kukhala chinthu chachikulu pakuwonongeka kwa chilengedwe.

Zotsatira zoyipitsa za pulasitiki

Mphamvu ya kuipitsa pulasitiki kumachitika m'njira zitatu. Zimakhudza dziko lapansi, madzi ndi nyama zamtchire. Ikakhala pansi, imatulutsa mankhwala, omwe amalowa m'madzi apansi ndi malo ena, pambuyo pake kumakhala koopsa kumwa madzi awa. Kuphatikiza apo, kupezeka kwa zinyalala m'mizinda kumawopseza chitukuko cha tizilombo tating'onoting'ono tomwe timathandizira kusintha kwa mapulasitiki. Kuwonongeka kwa pulasitiki kumatulutsa methane, mpweya wowonjezera kutentha. Izi zimayambitsa kukweza kwanyengo.

Kamodzi m'madzi am'nyanja, pulasitiki imawola pafupifupi chaka chimodzi. Chifukwa cha nthawiyi, zinthu zowopsa zimatulutsidwa m'madzi - polystyrene ndi bisphenol A. Awa ndi omwe amawononga kwambiri madzi am'nyanja, omwe akuwonjezeka chaka chilichonse.

Kuwononga pulasitiki kumawonongera nyama. Nthawi zambiri, nyama zam'madzi zimakodwa ndi zinthu zapulasitiki ndikufa. Ma invertebrate ena amatha kumeza pulasitiki, yomwe imakhudzanso moyo wawo. Nyama zazikulu zambiri zam'madzi zimamwalira ndi zinthu zapulasitiki, kapena zimalira misozi ndi zilonda zazikulu.

Zokhudza umunthu

Opanga zinthu zapulasitiki chaka chilichonse amasintha zinthu zawo posintha kapangidwe kake, ndikuwonjezera mankhwala atsopano. Mbali inayi, izi zimathandizira kwambiri mtundu wazogulitsa, komano, zimakhudza thanzi la munthu. Madokotala azachipatala apeza kuti ngakhale kukhudzana ndi zinthu zina kumatha kuyambitsa zovuta zina komanso matenda osiyanasiyana pakhungu.

Tsoka ilo, ogula ambiri amangoyang'ana mawonekedwe okongoletsa apulasitiki, osazindikira zovuta zomwe zimakhudza chilengedwe.
