Pamalo a 3.8 miliyoni miliyoni (km 9.8 miliyoni km2), ndi dziko lachitatu - kapena chachinayi padziko lonse lapansi kukhala malo onse. Ambiri mwa dzikolo ali chapakati North America pakati pa Canada ndi Mexico.

Nkhondo yaku Spain-ku America ndi Nkhondo Yadziko I idatsimikizira dzikolo kuti ndilo gulu lankhondo lapadziko lonse. United States idatuluka Nkhondo Yadziko II ngati mphamvu yapadziko lonse. Linali dziko loyamba kupanga zida zanyukiliya ndipo ndi dziko lokhalo lomwe adazigwiritsa ntchito kunkhondo. Panthawi ya nkhondo yozizira, United States ndi Soviet Union idachita nawo mpikisano mu Space Race, zomwe zidachitika ndi cholinga cha 1969 Apollo 11, kuwala kwa m'mlengalenga komwe kumayambitsa anthu pa Mwezi. Kutha kwa Cold War ndi kugwa kwa Soviet Union mu 1991 kunasiya United States ngati mphamvu yokhayo padziko lonse lapansi. United States ndi boma la federal komanso demokalase.

United States ndiyo wobweretsa kunja kwambiri padziko lonse lapansi komanso wotumiza kunja kwambiri kwachiwiri, pamtengo. Ngakhale kuchuluka kwake ndi 4% ya dziko lonse lapansi, limakhala ndi 29.4% ya chuma chonse padziko lapansi, gawo lalikulu kwambiri lazachuma padziko lonse lapansi lomwe limakhazikitsidwa mdziko limodzi. Ngakhale pali kusiyana pakati pa zopeza ndi chuma, United States ikupitiliza kukhala patsogolo pamilandu yachuma, kuphatikiza malipiro apakati, ndalama zapakatikati, chuma chapakatikati, chitukuko cha anthu, gawo lililonse la GDP, ndi kuchuluka kwa ogwira ntchito. Ndi gulu lankhondo lalikulu kwambiri padziko lonse lapansi, lopanga zoposa gawo limodzi mwa magawo atatu a ndalama zankhondo padziko lonse lapansi, ndipo ndi gulu lotsogolera lazandale, zachikhalidwe, ndi asayansi padziko lonse lapansi.Malo azaulimi nthawi zambiri amagwiritsidwa ntchito paulimi, [1] kachitidwe kagwiridwe kake ka mitundu ina ya moyo, makamaka kulera ziweto ndi kupanga mbewu, kuti apangire anthu chakudya. [2] [3] Chifukwa chake nthawi zambiri limafanana ndi minda kapena minda. Bungwe la United Nations la Food and Agriculture Organisation ndi ena omwe akutsatira tanthauzo lake, komabe, amagwiritsanso ntchito malo olimapo kapena malo azaulimi ngati nthawi ya luso, komwe akutanthauza kusonkhanitsa: [4] [5] "malo olimapo" (aka landland): Pano akufotokozeranso za nthaka yobzala yomwe ikufunikira pachaka kapena pang'onopang'ono kapena msipu womwe ukugwiritsidwa ntchito pazaka zisanu zilizonse "malo okhazikika": nthaka yopanga mbewu zomwe sizifunikira malo odyetserako ziweto osatha: madera achilengedwe kapena owumbako malo otsetsereka amatha gwiritsani ntchito kuweta ziweto Kutanthauza "malo olimidwa" motero kumaphatikizapo malo ambiri osagwidwa kapena kugwiritsidwa ntchito paulimi. Nthaka yomwe ili pachaka chokhazikika pachaka chilichonse pachaka chimanenedwa kuti ndi "nthaka yobzalidwa" kapena "nthaka yobzalidwa". "Dongosolo lokhalamo anthu 'limaphatikizapo minda yomwe ili m'nkhalango yomwe imagwiritsidwa ntchito pokolola khofi, mphira, kapena zipatso koma osati minda yamitengo kapena nkhalango zoyenera zogwiritsidwa ntchito ngati mitengo kapena matabwa. Malo omwe angagwiritsidwe ntchito kulima amatchedwa "malo olimidwa". Farmland, pakadali pano, imagwiritsidwa ntchito mosiyanasiyana kutanthauza malo onse azaulimi, nthaka yonse yomwe ingalimidwe, kapena lingaliro chabe "malo olimapo". Kutengera ndi kagwiritsidwe kake ka ulimi wothirira, "nthaka yaulimi" ya FAO ikhoza kugawidwa kukhala malo othirira komanso osathirira.Source: https://en.wikipedia.org/
