What is tragedy? tragedy is the conflict of good.

That's exhilarating if you're doing well, and very crushing if you're not. It leads, in the worst cases -- in the analysis of a sociologist like Emil Durkheim -- it leads to increased rates of suicide. There are more suicides in developed, individualistic countries than in any other part of the world. And some of the reason for that is that people take what happens to them extremely personally -- they own their success, but they also own their failure.

深海是地球上最后的伟大边疆，一个永恒黑暗和巨大压力的领域，却充满了生命。

Success is not final, failure is not fatal: it is the courage to continue that counts.

如果我们想保护海洋生物多样性，可持续的捕捞方式不是一种选择，而是一种必要。
