And we've got to get them all right, because if we solve 11, we fail to solve the 12th -- we're in trouble. For example, if we solve our problems of water and soil and population, but don't solve our problems of toxics, then we are in trouble.
我们必须将它们全部解决，要不然，就算我们成功解决了11个， 还剩下第12个，我们同样得完蛋。举例来说， 如果我们解决了水资源问题、土壤问题以及人口问题， 但没能解决有毒物质的问题，我们还是得陷入麻烦。
