You are not wrong about that, things have the value that we ourselves give them. In an apocalypse the only thing that has value is water and food and ironically the resources are wasted and the earth is destroyed in the end for nothing. I have a very unpopular opinion and it has even created debates between my husband and I, it is about gold, I understand the value of this in society, but I also think, is it worth destroying ecosystems, destroying the planet to get gold? If in the end gold does not quench thirst or hunger, what is the use of so much gold if we do not have a planet to inhabit? Perhaps with this I am going off topic, but it is one of the things I think about in silence.
