Uhulumeni omusha kaBiden uthe uzosebenzisana nezolimo zase-US ukulwa nokushintsha kwesimo sezulu. E-Iowa, lokhu kuyindida ethakazelisayo: inani elikhulu likaphethiloli okwamanje liyashiswa ukuze kukhiqizwe ukudla kwezilwane kanye ne-ethanol, okuwumkhiqizo oyinhloko wokulima umhlaba esifundazweni. Ngenhlanhla, uhlelo lukaBiden selumane luyisinyathelo manje. Lokhu kusinika isikhathi sokucabanga ngendlela yokushintsha indawo ngendlela ezuzisa imvelo kanye nezakhamuzi zakithi.
Intuthuko yezobuchwepheshe ingase ivumele imithombo yamandla avuselelekayo (umoya kanye nelanga) ukuthi idlule kumafutha angaphansi komhlaba ukuze kufezwe ukukhiqizwa kwamandla okuphumelelayo. Uma kuhlanganiswa nokuvela kwezimoto zikagesi, lokhu kuzonciphisa isidingo se-ethanol, esidinga ngaphezu kwengxenye yommbila wase-Iowa kanye nengxenye eyodwa kwezinhlanu zomhlaba. Abantu bayazi ukuthi i-ethanol ibilokhu ikhona namuhla. Ngisho namanje uMonte Shaw, umqondisi omkhulu we-Iowa Renewable Fuel Association, wakwenza kwacaca ekuqaleni kuka-2005 ukuthi i-ethanol yokusanhlamvu "iyibhuloho" noma uphethiloli wokuguquka futhi ngeke ibe khona unomphela. Njengoba ukwehluleka kwe-ethanol ye-cellulosic kuba ngokoqobo, sekuyisikhathi sokuthatha isinyathelo. Ngeshwa, ngendawo e-Iowa, imboni ayikaze isayine ifomu elithi "ungalulami".
Cabanga ukuthi izifunda ezingu-20 e-Iowa zinendawo engaphezu kwamakhilomitha-skwele angu-11,000 futhi zikhiqiza ugesi ovuselelekayo ngaphandle kokuguguleka kwenhlabathi, ukungcola kwamanzi, ukulahlekelwa yizibulala-zinambuzane, ukulahlekelwa yindawo yokuhlala, kanye nokukhiqizwa kwegesi yokushisa umhlaba ngenxa yokutshala ummbila. Lokhu kuthuthukiswa okukhulu kwemvelo kusezandleni zethu. Khumbula ukuthi umhlaba osetshenziselwa amandla omoya kanye nelanga ungafeza ezinye izinhloso ezibalulekile zemvelo ngasikhathi sinye, njengokubuyisela izindawo ezinde zotshani, okuzohlinzeka ngendawo yokuhlala yezinhlobo zezilwane zasendaweni, kufaka phakathi izimvemvane ze-monarch, ezitholakale muva nje e-United States Izinsizakalo zezinhlanzi nezilwane zasendle ezifanelekayo zezinhlobo ezisengozini yokuqothulwa. Izimpande ezijulile zezitshalo zotshani ezihlala isikhathi eside zibopha inhlabathi yethu, zibambe futhi zivalele amagesi okushisa umhlaba, futhi zibuyisele ukuhlukahluka kwemvelo endaweni ephethwe yizinhlobo ezimbili kuphela, ummbila kanye nobhontshisi. Ngesikhathi esifanayo, ukuhamba komhlaba e-Iowa kanye nokuhlafuna i-carbon kusezandleni zethu: ukukhiqiza amandla asebenzisekayo ngenkathi kunciphisa ukufudumala komhlaba.
Ukuze kufezwe lo mbono, kungani ungaqali ubheke amapulazi angaphezu kuka-50% ase-Iowa aphethwe ngabantu abangebona abezolimo? Mhlawumbe abatshalizimali abanandaba nokuthi umhlaba ungenisa kanjani imali—idola likagesi lisetshenziswa kalula eWest Des Moines, eBettendorf, eMinneapolis noma ePhoenix, futhi yilapho abaningi babanikazi bamapulazi ethu behlala khona, Futhi idola elilodwa livela ekutshaleni nasekuhluzeni ummbila.
Nakuba imininingwane yenqubomgomo ingase ishiywe kwabanye ukuthi bayisebenzise, ​​singacabanga ukuthi ukuncishiswa kwentela okusha noma intela kuzokhuthaza lolu shintsho. Kulo mkhakha, amasimu ommbila asetshenziswa ama-wind turbine noma izindawo ezivuselelwe kabusha ezizungeze amaphaneli elanga. Yebo, intela yempahla iyasiza ekulondolozeni amadolobhana ethu amancane nezikole zawo, kodwa umhlaba otshaliwe e-Iowa awusakhokhiswa intela enkulu futhi uzuzwa yinqubomgomo yentela yefa enhle. Ukuqashwa komhlaba nezinkampani zamandla kungenza noma kungenze bancintisane ngentela yokukhiqizwa kwezitshalo zasensimini, futhi kungathathwa izinyathelo zokulondoloza amadolobhana ethu asemakhaya. Futhi ungakhohlwa ukuthi ngokomlando, umhlaba wase-Iowa ngesimo sezibonelelo ezahlukene zamapulazi ube ukuncipha kwentela kahulumeni: kusukela ngo-1995, i-Iowa ibilokhu ibiza cishe u-$1,200 ngehektare, ingqikithi ingaphezu kwezigidigidi ezingama-35 zamaRandi. Idola. Ingabe le yinto engcono kakhulu izwe lethu elingayenza? Sicabanga ukuthi akunjalo.
Yebo, singacabanga ukuthi imboni yezolimo iphikisana kakhulu nalolu shintsho ekusetshenzisweni komhlaba. Phela, umhlaba osetshenziselwa ukukhiqizwa kukagesi awudingi imbewu eningi kakhulu, uphethiloli, imishini, amakhemikhali, umanyolo noma umshwalense. Bangase bakhale kithi. Noma echibini. Kuyisihawu kubantu base-Iowa, abakaze bakhathalele noma yimuphi wabo kuze kube manje. Bheka eduze umsebenzi abawenzile emaphandleni ase-Iowa eminyakeni engama-50 edlule. Ingabe le yinto engcono kakhulu imboni enamandla, exhumene nezepolitiki engayenza edolobheni elincane e-Iowa? Sicabanga ukuthi akunjalo.
Amandla avuselelekayo angenza izindawo zasemakhaya zase-Iowa zibukeke ngendlela entsha ngokuphelele: ukuthuthukisa umsebenzi, ukuthuthukisa umoya, ukuthuthukisa imithombo yamanzi, nokuthuthukisa isimo sezulu. Kanye ne-monarch.
