Poyamba, Tsiku la Dziko Lapansi linali lodzaza ndi zochitika za anthu: anthu adalankhula ndi kulimbikitsa ufulu wawo, amayi adamenyera nkhondo yofanana. Koma ndiye panalibe EPA, palibe Clean Air Act, palibe Water Water Act.
Pafupifupi theka la zaka zapita, ndipo lomwe linayamba ngati gulu lalikulu la anthu lasintha kukhala tsiku lapadziko lonse lachidwi ndi ntchito yodzipereka kuteteza chilengedwe.
Mamiliyoni a anthu amatenga nawo gawo pa Tsiku la Dziko Lapansi padziko lonse lapansi. Anthu amakondwerera pochita ziwonetsero, kubzala mitengo, kukumana ndi oimira am'deralo ndikuyeretsa malo.

Nkhani zingapo zovuta zachilengedwe zathandizira kuti pakhale kayendetsedwe kamakono ka chilengedwe.
Buku la Rachel Carson lakuti Silent Spring, lofalitsidwa mu 1962, linavumbula kugwiritsiridwa ntchito kowopsa kwa mankhwala ophera tizilombo otchedwa DDT amene anaipitsa mitsinje ndi kuwononga mazira a mbalame zodya nyama monga ziwombankhanga zadazi.
Pamene gulu lamakono la chilengedwe lidakali lachiyambi, kuipitsa kunali powonekera. Nthenga za mbalameyi zinali zakuda ndi mwaye. M’mlengalenga munali utsi. Tinkangoyamba kuganiza zokonzanso zinthu.
Kenako mu 1969, mafuta ambiri anatayikira m’mphepete mwa nyanja ya Santa Barbara, California. Kenako Senator Gaylord Nelson waku Wisconsin adapanga Earth Day kukhala tchuthi chadziko lonse, ndipo anthu opitilira 20 miliyoni adathandizira ntchitoyi.
Izi zidalimbikitsa gulu lomwe lidakakamiza Purezidenti wa US Richard Nixon kuti apange bungwe loteteza zachilengedwe. M'zaka kuyambira Tsiku loyamba la Dziko Lapansi, pakhala pali zopambana zazikulu za 48 zachilengedwe. Chilengedwe chonse chinali chotetezedwa: kuchokera kumadzi oyera kupita ku zamoyo zomwe zatsala pang'ono kutha.
Bungwe la US Environmental Protection Agency limagwiranso ntchito kuteteza thanzi la anthu. Mwachitsanzo, mtovu ndi asibesito, zomwe poyamba zinkapezeka ponseponse m’nyumba ndi m’maofesi, zachotsedwa kwambiri m’zinthu zambiri wamba.

Pulasitiki ndi imodzi mwazinthu zazikulu zachilengedwe pakali pano.
Pulasitiki ili paliponse - milu yayikulu ngati Great Pacific Garbage Patch, ndi micronutrients yodyedwa ndi nyama ndikutha pa mbale zathu zamadzulo.
Magulu ena oteteza zachilengedwe akukonzekera mayendedwe apansi kuti achepetse kugwiritsa ntchito mapulasitiki wamba monga udzu wapulasitiki; UK yaperekanso malamulo oletsa kugwiritsa ntchito kwawo. Iyi ndi njira imodzi yochepetsera kuchuluka kwa zinyalala za pulasitiki zosagwiritsidwanso ntchito, zomwe ndi 91%.
Koma kuwonongeka kwa pulasitiki si vuto lokhalo lomwe likuwopseza dziko lapansi. Mavuto amasiku ano oipitsitsa a zachilengedwe mwina ndi zotsatira za momwe anthu akhala akuchitira pa Dziko Lapansi kwa zaka mazana awiri zapitazi.
Jonathan Bailey, wasayansi wamkulu pa National Geographic Society anati: “Ziwiri mwa zinthu zofunika kwambiri zimene timakumana nazo masiku ano ndi kuwonongeka kwa malo okhala ndi kusintha kwa nyengo, ndipo nkhani zimenezi n’zogwirizana.
Kusintha kwanyengo kumasokoneza zamoyo zosiyanasiyana komanso chitetezo cha dziko. Zadzetsa zochitika monga kuwonongedwa kwa Great Barrier Reef ndi nyengo yachilendo.
Mosiyana ndi Tsiku loyamba la Dziko Lapansi, tsopano pali ndondomeko yowonjezereka yoyendetsera dziko lonse lapansi kuti alamulire ndondomeko ya chilengedwe ndi zotsatira zathu. Funso ndilakuti zipitilira mtsogolo.
Bailey adanenanso kuti kuthana ndi zovuta zachilengedwezi kumafuna kusintha kwakukulu. Iye anati: “Choyamba, tiyenera kuyamikira kwambiri chilengedwe. Ndiye tiyenera kudzipereka tokha kuteteza madera ovuta kwambiri. Pomaliza, akunena kuti tiyenera kupanga zatsopano mwachangu. Mwachitsanzo, kupanga bwino kwambiri masamba zomanga thupi ndi kulima zongowonjezwdwa magwero mphamvu zingathandize kuchepetsa zotsatira za zimene iye amaona chiwopsezo chachikulu pa Dziko Lapansi.
"Chimodzi mwazovuta zathu zazikulu ndi malingaliro athu: timafunikira anthu kuti azilumikizana ndi chilengedwe, kumvetsetsa momwe zimagwirira ntchito komanso kudalira kwathu," akutero Bailey. M’chenicheni, ngati timasamala za chilengedwe, tidzazilemekeza ndi kuziteteza ndi kupanga zisankho zomwe zidzatsimikizira tsogolo labwino la zamoyo ndi zachilengedwe.”
