研究人員說(shuō)，人類活動(dòng)使亞馬遜雨林變得更易燃。這是由一項(xiàng)關(guān)于巴西亞馬遜地區(qū)的研究所得出的結(jié)論之一，該結(jié)論表明即使是被保護(hù)的叢林也會(huì)受到影響。這項(xiàng)調(diào)查的成果已在《自然》期刊上發(fā)布。請(qǐng)聽(tīng) Victoria Gill 的報(bào)道。

(sound) The sound of burning rainforest. This is from footage captured by researchers in the Eastern Amazon. Their two-year study found that even selective logging in protected forests opened up the canopy enough to dry out theundergrowth and make it catch fire more easily.

To measure the impact of human activity on the rainforest, the team counted 2,000 species of trees, insects and birds, comparing biodiversity with the amount of forest cover, and you can hear the difference.

While a pristine undisturbed rainforest sounds like this (sound), far fewer species contribute to the chorus when the forest is degraded (sound).

This large-scale study showed that areas with 80% forest cover lost up to half their biodiversity.
