Huxley, I completely understand how you feel. The world right now does feel somehow worse than, say a couple of years ago. The pandemic is frightening, as are the riots (though understandable, IMHO, given systemic racism). It does feel, at least to me, that the overall situation is different. Still, I ask myself whether these events actually fulfill what JWs say characterize the last days: food shortages, disease, earthquakes, war. If you do some research, the answer quickly becomes--no.
The main threats we face right now are due to environmental degradation and economic inequality (which is being exacerbated by climate change). COVID-19, while frightening, is relatively mild compared to pandemics of the past (such as the Spanish Influenza). Moreover, it has been a century since there has been a global pandemic to compare. Rather, the time period constituting the "last days" according to JWs has been characterized by a dramatic reduction in global mortality due to disease, along with a corresponding increase in global food supply. Hence, the sharp increase in population. Along with it, the last thirty years has seen widespread economic upturns, improving the everyday life of literally billions of people. In fact, in 2014, there were more obese people on the planet than malnourished, a little fact you won't find anywhere on the JW website.
Alas, economic expansion has brought along with it extreme depletion of natural resources and widespread pollution, including plastic waste. But this very phenomenon is a result of economic development, not of worsening famine and disease and other physical woes. Similarly, the level of global warfare has been at an all-time low since the end of WWII, about 70 years ago (hey, a generation!!), so much so that historians have described this time period as the Pax Americana or Great American Peace (take that as you like, but still, the point is that it has been a relatively/comparatively peaceful and prosperous time).
So--reasons to be anxious? Yes. But evidence of JW's accuracy in describing our time period? No.
I've learned a lot from a variety of sources including Our Word in Data. Highly recommended.
