periodic famines周期性饥荒
Deforestation starts a vicious circle of drought and environmental decline. Burning wood releases the carbon stored inside. And deforestation accounts for at least a fifth of all carbon emission globally. As tree cover vanishes, the land dries out the soil erodes and become barren – a major reason for Ethiopia’s periodic famines.
语法点：雅思阅读文章中 - 逻辑词为主，所以这段话中1.and 并列名词短语；2and并列两个句子；3and并列动词。
理解：砍伐森林的后果是带来干旱和环境衰退的恶性循环。燃烧木头会释放出内存的碳物质。并且砍伐森林造成至少全球1/5的碳排放。随着林木植被的消失，土地干涸、土壤侵蚀变得贫瘠 – 这是埃塞俄比亚周期性饥荒的主要原因。
这篇文章是个对于写作很好的素材，关于环境话题，我们来整合下证明观点human activities negatively impact environment. 支持的时候就可以说，deforestation is proved as one main reason leading to environmental decline,which accounts for a fifth of all carbon emissions globally. If not controlled well, this problem will cause a vicious circle of environmental degradation.
