用unless改写句子

我认为呢,the whole world 后面一定还有一个词，整句意思是想表示如果我们不对他人善意世界就会变得..少了会变成什么样，改写这么写可以吗the world will become( 某种样子)unless everyone give their's charity to others

the whole word will become if everyone of us not give charity to other
我也被这句搞糊涂了`！ 我觉得我的答案有问题`！ 但是还是让别人分析下！

The whole word won't become unless everyone of us gives charity to others.
