Pfupisa nyaya yacho:  (CNN) Makore mashanu pashure pokuputika kwechikepe chinotakura mafuta chinonzi Deepwater Horizon chakaparira kudonha kukuru kwazvo kwemafuta mugungwa munhoroondo yenyika, tichiri kuona - asi tichangotanga kunzwisisa zvechokwadi - migumisiro yakakura yezvakatipoteredza neyezveupfumi. Migumisiro yokudonha kwemafuta yakanyatsozivikanwa, nokuderera kwebasa rokushanyira nzvimbo uye indasitiri yezvokudya zvomugungwa, pamwe chete nokuparadzwa kukuru kwemhuka dzomusango munharaunda yacho. Kubvira ipapo, uwandu hwemafuta munharaunda yacho hwapera uye nzanga dzakatanga kuratidza zviratidzo zvokupora. Kutaura idi, mishumo inoratidzira kuti indasitiri yezvokudya zvomugungwa yeGulf of Mexico, iyo inopa United States inenge 40% yezvokudya zvayo zvomugungwa, iri kutanga pakupedzisira kupora. Zvisinei, zvinetso zvikuru zvinoramba zviripo, muchidimbu nemhaka yokuti mibvunzo yakawanda kwazvo pamusoro pemigumisiro yenguva refu inoramba isina kupindurwa. Kusvikira kuzuva rino, kuchiri kusajeka kuti mafuta ose aya aenda kupi, kuti mangani akanyatsowanikwa kana kuti kuonekazve kwemhuka dzomusango mugumisiro wokugadziridza kana kuti chiratidzo chokuti dambudziko racho riri kupera zvechokwadi here. Imwe yenzanga dzinogona kupa nzwisiso yemibvunzo iyi inonzi Gulf crab. Makunguo anoita basa rinokosha munharaunda yacho: Anenge mapaundi mamiriyoni 60 akabatwa muGulf muna 2012, achiwana mari inoita makumi emamiriyoni. Asi pashure pokunge mvura yabuda, kuchinja kwakaitika munzanga dzezvipembenene zvomunharaunda yacho kwaiva pachena. Vatsvakurudzi vakanyora misiyano mikuru muchitarisiko, nokushanduka-shanduka muzvinyavada izvo zvakakanganiswa nokudeuka kubatanidza kuvadziko dzakawanda kwazvo idzo dzakadya nomumapfundo, dzichimanikidzira mitezo kuti iwa. Izvi hazvina kungokanganisa kukosha kwemakwenzi pamusika chete asiwo kukwanisa kwawo kurarama. Nepo kuchinja uku muchitarisiko chokunze kwakapera munguva pfupi, utano hwehove idzi hunogona kuva huchiri kutyisidzira. Ndanga ndichishanda nevamwe vangu paFlorida International University uye paUniversity of Louisiana paLafayette kuti ndinzwisise zviri nani zvingave zvichiitika mumuviri womukamba paanenge achionekwa nemafuta uye...
