I think, in general, these are correct and understandable thoughts. Man, in my opinion, is the most harmful creature on earth and all that he does is only for his own benefit. It seems that everyone understands the most important global problems, but no one does anything to prevent this. Our world has long turned the wrong way and, most likely, irrevocably. Mankind has absorbed the thirst for profit, and in all aspects, economic benefits are in the first place. Perhaps technologies such as blockchain will partly be able to positively influence the situation.
