translation.en: We did estimates in our study that for countries like Brazil, India and Indonesia, even though ecosystem services -- these benefits that flow from nature to humanity for free -- they're not very big in percentage terms of GDP -- two, four, eight, 10, 15 percent -- but in these countries, if we measure how much they're worth to the poor, the answers are more like 45 percent, 75 percent, 90 percent.
translation.zh: 我们在研究中做了如下估计： 对于像巴西、印度、印尼这样的国家， 即使生态系统提供了充足资源-- 这些是人类可免费从大自然获取的-- 从国内生产总值来看，也没占多大比例-- 大约2%，4%，8%，10%，15%左右-- 但在这些国家中，如果我们来看自然资源对于穷人来说占生产总值的比例， 那么，这个答案更加可能是 45%，75%，90%。
