Scientific Morality

It is possible for individuals and even human cultures to care about things destructive for human civilization (1)

Probably well-known ideas, but what I find important is that the presenter talks about the necessity to identify common moral norms for the whole world - makes sense as the communication is so global now, that it is difficult to separate, close eyes and eventually - yes, we have to protect ourselves from self-desctuction, which is probably the base of these moral norms, otherwise they are not necessary :-)
