On August 8, 2009, a deluge shocked the entire Taiwan off an otherwise joyful holiday. Not only was the erratic anddestructive power of Nature felt, but a valuable yet hurtful lesson was learned: man must not misuse natural resourcesanymore. Only when the sustainability of national land is maintained will the peaceful coexistence between humans and Natureensue. This issue of NPQ begins with a deep introspection on the effect brought by Typhoon Morakot as former Director-generalof CPAMI Lung-sheng Chang and NTU professor Shin Wang give a wake-up call on national land conservation, followed by athorough analysis by NTU professors Jiun-chuan Lin and Jong-dao Jou on soil and the damages heavy rain may cause, whileNTU emeritus professor Pao-chang Kuo shares his idea of the connection between typhoons and forests. Afterwards, enjoy a trip to Taroko with touching stories of the selfless contributions made by aborigine rangers for over 20years. And listen to a different perspective of photography ethics shared by nature photographer Jen-hsiu Hsu. Finally, watchan in-depth report on the development of Taijiang National Park to savor humanities of Taiwan and primitive beauty of thelagoon of Taijiang and to celebrate this milestone in national park's history. Shouldering heavy responsibilities of conservation, national parks act as giant trees standing straight for generations andholding the land in place against every storm. With qualities of humbleness and perseverance, the parks will surely protect theland of Taiwan and pass on the sustainable energy forever and ever.
