In response to the global trend of rising levels of atmospheric carbon dioxide, the government is encouraging large-scale reforestation. But rapid planting of single-species forests in previously cleared areas implies that in the future, each such area will contain only one producer species, thus limiting biodiversity and creating incomplete and fragmentary food chains.
因應全球二氧化碳增加的趨勢，政府推動大量造林，但短期內在人為開發過的環境造純林，代表的是未來土地上的生產者只有一種，無法孕育生物的複雜度，如此創造出的是殘缺不全的食物鍊。
