Amahlathi emvula amele ngaphezu kuka-50% wayo yonke indawo eluhlaza emhlabeni. Zingaphezu kwama-80% izinhlobo zezilwane nezinyoni ezihlala kula mahlathi. Namuhla, ukugawulwa kwamahlathi emvula kwenzeka ngokushesha okukhulu. Izibalo ezinjalo ziyesabisa: ngaphezu kwezihlahla ezingama-40% sezivele zigawulwe eNingizimu Melika, kanye nama-90% eMadagascar naseNtshonalanga Afrika. Konke lokhu kuyinhlekelele yemvelo yemvelo yomhlaba.
Ukubaluleka kwehlathi lemvula
Kungani ihlathi libaluleke kangaka? Ukubaluleka kwehlathi lemvula leplanethi kungabalwa ngokungapheli, kepha ake sihlale emaphuzu abalulekile:
- ihlathi lithatha ingxenye enkulu emjikelezweni wamanzi;
- izihlahla zivikela inhlabathi ekukhukhulekeni futhi ipheshulwe umoya;
- ukhuni luhlanza umoya futhi lukhiqize umoya-mpilo;
- ivikela izindawo ekushintsheni okungazelelwe kokushisa.
Amahlathi emvula angumthombo ozivuselela kancane kancane, kepha izinga lokugawulwa kwamahlathi libhubhisa inani elikhulu lezinto eziphilayo emhlabeni. Ukugawulwa kwamahlathi kuholela ekushintsheni kokushisa okungazelelwe, izinguquko ngejubane lomoya nemvula. Lapho izihlahla zingakhuli kangako eplanethi, yilapho i-carbon dioxide ingena kakhulu emkhathini futhi nomphumela wokubamba ukushisa uyanda. Amaxhaphozi noma izingwadule nezingwadule kuyakheka esikhundleni sokugawulwa kwamahlathi ashisayo, izinhlobo eziningi zezimila nezilwane ziyanyamalala. Ngaphezu kwalokho, amaqembu ababaleki bezemvelo ayavela - abantu ihlathi ebeliwumthombo wokuziphilisa ngalo, futhi manje sebephoqeleka ukuthi bafune ikhaya elisha nemithombo yemali.
Ungasindisa kanjani ihlathi lemvula
Ochwepheshe namuhla basikisela izindlela eziningana zokulondoloza amahlathi emvula. Wonke umuntu kufanele ajoyine lokhu: sekuyisikhathi sokushintsha kusuka kubathwali bemininingwane yamaphepha uye kwabakwa-elekthronikhi, ukudlulisa iphepha lodoti. Ezingeni likahulumeni, kuhlongozwa ukuba kwenziwe uhlobo lwamafamu asehlathini, lapho kuzotshalwa khona izihlahla ezifunwayo. Kuyadingeka ukuvimbela ukugawulwa kwamahlathi ezindaweni ezivikelwe kanye nokuqinisa isijeziso sokwephula lo mthetho. Futhi ungakhuphula isibopho sikahulumeni ngokhuni lapho usithumela kwelinye izwe, ukuze wenze ukuthengiswa kwezinkuni kungasebenzi. Lezi zenzo zizosiza ekulondolozeni amahlathi emvula eplanethi.
