The shortage of natural resources and the destruction of the natural environment are two colossal problems that are now threatening our existence. These seemingly two problems are just one problem ― the problem of entropy. On this page, I will show that the essence of the two problems is entropy and that the key to resolving them consists in how to decrease entropy. So, first, let me explain what entropy is.

You can imagine a culture as a correlate to self-sufficient economy where everyone could collect information and create works solely by himself without any communication with the others. Actually, however, we exchange commodities through money and views through language.

Why does money have value and circulate, though it does not have value in itself? I will answer this question in terms of the system theory.

A social system is not just a gathering of people. It does not consist in the interaction between people either. You can find a mere causal interaction between things.
