目前，全球的生物多樣性正處于危機(jī)之中。風(fēng)景園林師們有著前所未有的機(jī)遇和不可推卸的責(zé)任，去運(yùn)用我們的技能和知識(shí)，減少對(duì)現(xiàn)有生物多樣性的損害，同時(shí)尋找機(jī)會(huì)去恢復(fù)或重建生物多樣性。綠色城市運(yùn)動(dòng)和綠色基礎(chǔ)設(shè)施概念的提出為我們創(chuàng)造了大量的機(jī)會(huì)和挑戰(zhàn)，假如把生物多樣性比作一座圖書館，我們需要保護(hù)我們已有的書籍，同時(shí)還要寫下更多的書，為后代將要面對(duì)的挑戰(zhàn)打下基礎(chǔ)。
