Phuputso e ncha e entsoeng ke National Park Foundation e hlahloba lipaka tsa boikhathollo tsa Amerika ka boiteko ba ho lekanyetsa boleng ba bona ba moruo. Liphello tsa lipatlisiso tseo li hlahisitse linomoro tse bonang mahlo, li re fa mohopolo o molemo oa hore na libaka tsena tsa setšoantšo li bohlokoa hakae.

Phuputso e ne e khannoa ke Dr. John Loomis le Michelle Haefele, Motlatsi oa Lipatlisiso oa Colorado State University, ea neng a sebelisana le Dr. Linda Bilmes oa Harvard Kennedy School.
Ba bararo ba ile ba leka ho beha "tekanyo ea moruo" (TEV) lirapeng tsa boikhathollo tsa sechaba, tse sebelisang tlhahlobo ea litšenyehelo bakeng sa ho leka ho fumana boleng boo batho ba bo fumanang mohloling oa tlhaho. Tabeng ena, thepa ea tlhaho ke lirapaka tsa boikhathollo.
Kahoo, libaka tsa boikhathollo tsa naha li bohlokoa hakae ho ea ka thuto? Kakaretso ea tekanyo ea liphutheloana, le mananeo a National Park Service, ke $ 92 limilione tse likete tse hlollang. Nomoro eo ha e kenye liphutheho tse 59 feela tsa naha, empa lihlopha tse ngata tsa sechaba, libaka tsa ntoa, libaka tsa histori, le lihlopha tse ling tse oelang tlas'a sekhele sa NPS. E boetse e kenyeletsa mananeo a bohlokoa a kang Mokotla oa Polokelo ea Naha le Metsi le Lenaneo la Sechaba sa Litša tsa Tlhaho. Boitsebiso bo bongata bo ile ba bokelloa e le karolo ea lipatlisiso tse kholo tse batlang ho lekanyetsa boleng ba tsamaiso ea tikoloho ea lintho, tlhaho ea thepa ea boitsebiso, thuto le likarolo tse ling tse ka ba le phello "boleng."
"Phuputso ena e bontša bohlokoa ba sechaba bo etsoang mosebetsing oa National Park Service, esita le ka nģ'ane ho libaka tse ikhethileng le tse hlollang tse tlhokomelong ea rona," ho buuoa ka Jonathan B.

"Ka ho netefatsa boitlamo ba rona mananeong a re thusang ho boloka setso le histori ea Amerika ho ea sebakeng se seng, thuto ena e fana ka moelelo o moholo bakeng sa tataiso ea National Park Service e tla falla lekholong la bobeli la lilemo ho bolella pale e fapaneng le e fapaneng ea hore na re bo-mang le seo re se nkang e le sechaba sa bohlokoa. "
Bohlokoa bo bongata ba moruo ea liphutheloana e ne e se eona feela molao o thahasellisang o tsoang mosebetsing ona. Ha a bua le batho ba neng ba hlahlojoa ha ba ntse ba bokella boitsebiso, bafuputsi ba ile ba fumana hore sechaba sa Maamerika sa 95% se na le maikutlo a hore ho sireletsa libaka tsa boikhathollo tsa naha le libaka tse ling tsa bohlokoa bakeng sa meloko e tlang e ne e le boiteko ba bohlokoa. Boholo ba batho bao ba ne ba boetse ba ikemiselitse ho beha chelete ea bona melomong ea bona, ka 80 lekholong ba re ba tla ikemisetsa ho lefa lekhetho le phahameng haeba ho bolela hore liphutheloana li ne li tšehetsoa ka ho feletseng le ho sireletsa ho tsoela pele.
Tlhōrō ea liranta tse limilione tse likete tse 92 e itšetlehile ka tlaleho ea National Park Foundation ea Baeti ba Tlaleho ea Litlhahiso e ileng ea lokolloa morao ka 2013.

Ho feta moo, ho ile ha hakanngoa hore mesebetsi e ka bang 238 000 e ile ea bōptjoa ka lebaka la libaka tsa boikhathollo hammoho le ho eketsa tšusumetso ea moruo. Linomoro tseo li ka 'na tsa hōla lilemong tse' maloa tse fetileng, leha ho le joalo, kaha libaka tsa boikhathollo li bone linomoro tsa palo ea baeti ka 2014 le 2015.
Phuputso ena ea morao-rao e se e fetile ho hlahloba lithaka, e leng mokhoa o tloaelehileng lefats'eng la thuto. E tla boela e romeloe bakeng sa ho hatisoa likoranteng tsa thuto, moo ho seng pelaelo hore e tla hlahlojoa hape.
