A watan Yuni na shekarar 1960 ne, kungiyar hasashen yanayi ta kasa da kasa, ta zartas da kudurin sanya ranar 23 ga watan Maris na ko wace shekara, ya zamo ranar hasashen yanayi ta kasa da kasa.
Babban taken ranar hasashen yanayi na shekarar bana shi ne, fuskantar kalubalen samun karuwar zafi, da karin fari, da kuma karin ambaliyar ruwa a gaba. (Maryam)
