Boma la Biden lomwe likubwera lati lidzagwirizana ndi ulimi wa ku America kuti lithane ndi kusintha kwa nyengo. Kwa Iowa, izi ndi zodabwitsa: mafuta ambiri akuwotchedwa kuti apange chakudya cha ziweto ndi mafuta a ethanol, chomwe ndi chinthu chachikulu chomwe chimagwiritsidwa ntchito polima nthaka m'boma. Mwamwayi, dongosolo la Biden ndi longosintha tsopano. Izi zimatipatsa nthawi yoganizira momwe tingasinthire malo m'njira yopindulitsa chilengedwe ndi nzika zathu.
Kupita patsogolo kwa ukadaulo kungalole kuti magwero amphamvu obwezerezedwanso (mphepo ndi dzuwa) azitha kudutsa mu mafuta kuti apange magetsi moyenera. Kuphatikiza ndi kubuka kwa magalimoto amagetsi, izi zichepetsa kufunikira kwa ethanol, komwe kumafuna chimanga choposa theka la Iowa ndi gawo limodzi mwa magawo asanu a nthaka. Anthu amadziwa kuti ethanol yakhalapo masiku ano. Ngakhale tsopano Monte Shaw, mkulu wa bungwe la Iowa Renewable Fuel Association, adafotokoza momveka bwino mu 2005 kuti ethanol ya tirigu ndi "mlatho" kapena mafuta osinthira ndipo sidzakhalapo kwamuyaya. Popeza kulephera kwa ethanol ya cellulosic kukuchitika, ndi nthawi yoti tichitepo kanthu. Mwatsoka, kwa chilengedwe ku Iowa, makampaniwa sanasayinepo fomu ya "musabwererenso".
Tangoganizirani kuti maboma 20 ku Iowa ali ndi malo opitilira ma kilomita 11,000 ndipo amapanga magetsi obwezerezedwanso popanda kukokoloka kwa nthaka, kuipitsa madzi, kutayika kwa mankhwala ophera tizilombo, kutayika kwa malo okhala, ndi kupanga mpweya wowonjezera kutentha chifukwa cha kubzala chimanga. Kusintha kwakukulu kwa chilengedwe kumeneku kuli m'manja mwathu. Kumbukirani kuti malo ogwiritsidwa ntchito pamphepo ndi mphamvu ya dzuwa nthawi imodzi amatha kukwaniritsa zolinga zina zofunika zachilengedwe, monga kubwezeretsa malo okhala udzu wautali, zomwe zipereka malo okhala nyama zakuthengo, kuphatikiza agulugufe a monarch, omwe apezeka posachedwapa ku United States Ntchito zoyenerera za nsomba ndi nyama zakuthengo za mitundu yomwe yatsala pang'ono kutha. Mizu yakuya ya zomera za udzu wosatha imamangirira nthaka yathu, kugwira ndikutseka mpweya wowonjezera kutentha, ndikubwezeretsa zamoyo zosiyanasiyana ku malo omwe pakadali pano akulamulidwa ndi mitundu iwiri yokha, chimanga ndi soya. Nthawi yomweyo, kuyenda kwa nthaka ku Iowa ndi kutafuna kaboni kuli mkati mwa mphamvu zathu: kupanga mphamvu zogwiritsidwa ntchito pochepetsa kutentha kwa dziko lapansi.
Kuti tikwaniritse masomphenya awa, bwanji osayang'ana kaye zoposa 50% ya minda ya ku Iowa yomwe ili ya anthu omwe si alimi? Mwina amalonda sakusamala momwe nthaka imapezera ndalama - dola imodzi yamagetsi imagwiritsidwa ntchito mosavuta ku West Des Moines, Bettendorf, Minneapolis kapena Phoenix, ndipo apa ndi pomwe eni minda athu ambiri amakhala, Ndipo dola imodzi imachokera ku kubzala ndi kusungunula chimanga.
Ngakhale tsatanetsatane wa mfundozi ungakhale bwino kuti ena azigwiritsa ntchito, tingaganize kuti kuchepetsa misonkho kapena misonkho yatsopano kudzalimbikitsa kusinthaku. M'munda uno, minda ya chimanga imagwiritsidwa ntchito ndi ma turbine amphepo kapena malo omangidwanso ozungulira ma solar panels. Inde, msonkho wa katundu umathandiza kusamalira matauni athu ang'onoang'ono ndi masukulu awo, koma malo olimidwa ku Iowa sakulipiranso msonkho waukulu ndipo amapindula ndi ndondomeko yabwino ya msonkho wa cholowa. Kubwereketsa malo ndi makampani opanga mphamvu kungathandize kapena kungapangitse kuti azipikisana ndi lendi yopangira mbewu za m'munda, ndipo njira zitha kutengedwa kuti zisunge matauni athu akumidzi. Ndipo musaiwale kuti m'mbuyomu, malo a Iowa monga ndalama zothandizira ulimi akhala akuchepetsa misonkho ya boma: kuyambira 1995, Iowa yakhala pafupifupi $1,200 pa ekala, yokwana madola oposa 35 biliyoni. Dola. Kodi ichi ndiye chinthu chabwino kwambiri chomwe dziko lathu lingachite? Tikuganiza kuti sichoncho.
Inde, tingaganize kuti mafakitale a zaulimi akutsutsa kwambiri kusinthaku kwa kagwiritsidwe ntchito ka nthaka. Kupatula apo, malo omwe amagwiritsidwa ntchito popanga magetsi safuna mbewu zambiri, mafuta, zida, mankhwala, feteleza kapena inshuwaransi. Angatilirire. Kapena nyanja. Ndi chisoni kwa anthu aku Iowa, sanasamale za aliyense wa iwo mpaka pano. Yang'anani mosamala ntchito yomwe achita kumidzi ya ku Iowa m'zaka 50 zapitazi. Kodi ichi ndi chinthu chabwino kwambiri chomwe makampani amphamvu, ogwirizana ndi ndale angachite ku tawuni yaying'ono ku Iowa? Tikuganiza kuti sichoncho.
Mphamvu zongowonjezedwanso zingapangitse madera akumidzi a Iowa kukhala ndi mawonekedwe atsopano: kukonza ntchito, kukonza mpweya, kukonza magwero a madzi, komanso kukonza nyengo. Ndipo mfumu.
