Kurakl\u0131k, Kaliforniya’n\u0131n \u00e7evresi, ekonomisi ve toplumu \u00fczerinde \u00f6nemli bir etkiye sahip.

Kurakl\u0131k, eyaletin ekonomisi \u00fczerinde de olumsuz bir etkiye sahip.

Kurakl\u0131k, eyalete ayr\u0131ca milyarlarca dolarl\u0131k gelir kayb\u0131na mal oluyor.<\/p>\n\n
Kurakl\u0131k, Kaliforniya i\u00e7in ciddi bir sorundur ve eyaletin bunu ele almak i\u00e7in harekete ge\u00e7mesi \u00e7ok \u00f6nemlidir. Buna su tasarrufu \u00f6nlemlerine yat\u0131r\u0131m yapmak, yeni su kaynaklar\u0131 geli\u015ftirmek ve iklim de\u011fi\u015fikli\u011finin etkilerini hafifletmek i\u00e7in sera gaz\u0131 emisyonlar\u0131n\u0131 azaltmak da dahildir.<\/p>\n\n
