drought中等

Already, since 2010, drought and insects have killed over 100 million trees in California, most of them in 2016 alone, and wildfires have burned hundreds of thousands of acres.

自2010年以来，干旱和虫害已经导致加州超过1亿棵树木死亡，其中大部分仅在2016年就已死亡，而野火已烧毁了数十万英亩土地。

That's only a small share of the total acreage that could benefit, about half a million acres in all, so it will be vital to prioritize areas at greatest risk of fire or drought.

这仅占可受益总面积（总计约50万英亩）的一小部分，因此优先处理火灾或干旱风险最大的地区将至关重要。
