While seeing the Earth as a whole diminishes the importance of things like national boundaries that divide us, he said, it also “underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.” Al Gore used the “pale blue dot” image at the end of his film, An Inconvenient Truth, suggesting that if we wreck this planet, we have nowhere else to go.
萨根也持有相似的观点。当看到我们的地球只是一个微小的一点时，有关谈论到国家界限此类重要问题的时候，他说，“不用太过于关注我们国与国之间的关系，我们应该珍惜我们这个 暗淡蓝点 ，这是我们唯一可以生存的家园。”戈尔在他的电影《难以忽视的真相》的结尾以“ 暗淡蓝点 ”来结束时说道，如果我们破坏了星球，我们就无立足之地。
