The world has always been changing in quantifiable ways. Today's social media has not been more impactful, socially, than printed press, the telegraph, the telephone, television, the computer, cell phones or the internet first were. Climate change has been an issue since a lot longer than you probably realize; and before that, environmental issues not under the umbrella term certainly were. I'm not even going to discuss geopolitical alignment. In historical terms, there's really not much to be seen here today.
