I think there's a sense that many of us have that the great age of exploration on Earth is over, that for the next generation they're going to have to go to outer space or the deepest oceans in order to find something significant to explore.
我想我们中的绝大多数有种观念， 那就是，地球上的大探索时代已经结束， 我们的下一代人 应该去外太空或者海洋最深处 从而去寻找值得探索的东西。
