如果不是更多 meaning in Chinese

if not more

No one can deny the unprecedented material benefit of science and technology , but our basic human problems remain ; we are still faced with the same , if not more , suffering , fear , and tension
没有人可以否定科技所带来的物质好处，但我们基本的人类问题依然存在，我们仍然要面对同样的，如果不是更多的，苦难、恐惧和紧张。
But i share your view that if we are successfully to manage the risks of globalisation we should be spending as much time and effort - if not more ? dealing with the insecurities which are the constant undercurrent to global tension
我同意中国的看法，即如果我们想要处理好全球化风险，我们应该尽可能花费同样的时间和精力，如果不是更多，来对待国际紧张局势之下暗藏的不安全因素。
