challenges and conflicts persist, and the trajectory of human development is influenced by a multitude of factors, including social, political, economic, and environmental dynamics. Whether humanity as a whole becomes "better" is contingent on our ability to address global issues such as inequality, climate change, conflict resolution, and the ethical use of emerging technologies
You know. In my opinion one of the biggest obstacles when comes to addressing global problems is that many people have grown skeptical on the scientific approaches to solved them, it was not like that before.
For example, remember the problem with the ozone layer? Scientist got together and warned the world about the danger which was ahead if people did not stop using flour-carbon in cooling systems and aerosols, slowly but steadily people started to change those harmful chemicals and we managed to save the ozone layer before something even more serious happened.
Nowadays, with the climate change there are so many people who do not even acknowledge there is a problem or even deny the existence of climate change, a lot of the common sense has gotten lost since the 90s.
